in indonesia. we begin in michigan and the continuing fallout from tuesday's deadly school shooting. police say another person could face charges for helping the parents of the alleged shooter. james and jennifer crumbley have pleaded guilty to involuntary manslaughter charges and are each being healthld on a $500,0 bond. i should say, they pleaded not guilty. the video of the couple being taken into custody from a warehouse in detroit after setting off a fugitive manhunt. police say someone aided the pair while they were there. >> we believe they were assisted in that location, to get there, to get in. and we're gathering that information. and we're going to have the totality of that done fairly soon. and present that to our prosecutor for potential charges for either aiding and abetting or obstruction of justice. >> now during the wcrumbleys' arraignment, their attorneys claimed they had fully intended to turn themselves in. they deny their son had unrestricted access to the gun he's accused of using in the shooting, of course. >> reporter: james and jennifer crumbley found hiding in a detroit warehouse early saturday morning. they were arraigned later in the morning. each faces four counts of involuntary manslaughter, the death of the four teens that their son, ethan crumbley, is charged with murdering. each of these counts of involuntary manslaughter carries up to 15 years in prison and a $7,500 fine and mandatory dna collection. it is very, very rare to see the parents charged in a high school shooting case, but oakland county prosecutor karen mcdonald explained why she was making that move, take a listen. >> both defendants were aware that he was searching "ammunition" on his phone at school, instead of reacting to that as a concerned parent and worried about safety, mrs. crumbley texted, "lol, i'm not mad, just next time don't get caught." then obviously on this very tragic day, on the 30th, they were called to the school about their son's drawing, which literally depicted threats and acts of violence. and instead of disclosing to the school that he had full access to this weapon, they chose not to. they chose not to take their son home. they chose not to tell anybody that he might be dangerous, when it was clear and they had every likelihood that he was. and instead, they left. >> reporter: and instead they left. the prosecutor saying these parents, had they acted, could have prevented this tragedy from happening, therefore, they are criminally negligent. we did hear from the lawyers representing jennifer and james crumbley. they insist that even though the crumbleys did not show up for their arraignment on friday, they were not, in fact, fleeing. take a listen to what one of the lawyers had to say. >> last night and throughout the day, we were in contact with our clients. they were scared, they were terrified. they were not at home. they were figuring out what to do, getting finances in order. this case is absolutely the saddest, most tragic, worst case imaginable. there is absolutely no doubt. but our clients were absolutely going to turn themselves in. it was just a matter of logistics. and all the prosecution had to do was communicate with me about it. >> reporter: they say this was all about miscommunication. but the oakland county prosecutor and sheriff say, look, the crumbleys went to a nearby atm, withdrew $4,000, they did this at a place that wasn't far from the place they were expected to turn themselves in. that doesn't seem like someone who was trying to turn themselves in. one more thing i should note, there was a person, a third person who police say helped them get into the warehouse where they were found hiding. that person could face charges as well, aiding and abetting or obstruction of justice. those exact charges will be up to the oakland county prosecutor. >> joining me from new york, cnn legal analyst joey jackson. another crazy turn of events in the last 24 hours. i want to get to those most recent developments. what do you make of those parents, their lawyers, and the lawyers' accusations that the prosecutor didn't handle the situation properly? it was quite a back and forth. >> yeah, it really was. i know you're speaking about the arraignment. backing up one minute, the whole purpose of arraignment is to, number one, apprise the parents what was they're charged with. number two, for the parents to enter a plea, which they did, not guilty. number three, for bail to be set, which we know it was set. ultimately, to have the case come back. and at that particular arraignment, there were some accusations. the defense pretty much indicating that their clients were never absconding from jus justice, that there was a miscommunication with the prosecutor, and that they, that is, the defendants who they represent, the crumbleys, at all times had intended to turn themselves in. the only issue with that is that it pretty much belies the facts as we know them. in the event that you get assistance to get into a warehouse, in the event that you're hiding in the warehouse, in the event that you take out $4,000 the day before, which may be indicative of you pretty much planning to go somewhere. it sort of is contrary to an allegation that they were not really absconding. so ultimately, everything turns on its facts. we'll see what's factually accurate, what's not. bail was set. we'll see when they appear in court with regard to their criminality and the prosecutor's case, whether there can be a conviction moving forward. >> this must come as relief to the parents at that high school and the kids now that these parents are in custody. to be clear, michigan prosecutors will now try and prove that those parents were grossly negligent. what about the school, joey? you know we've had cnn journalists on the ground for days. they reported to us that the parents and students are fuming at school officials, believing that more could have been done. what were the school's legal obligations here? >> yeah, i have to tell you, paula, that's a valid concern. and we know obviously as it relates to the parents, you noted it's about their carelessness, it's about them creating this situation and condition which led to the deaths and the injuries. so we know they're being prosecuted. when you pivot to the school, it's about what they knew, when they knew it what specifically they did about it. apparently the school did have knowledge as to this child and misbehavior. there's indication that he was looking on his phone for ammunition, doing an ammunition search. that concerned school officials enough where they spoke with him are subsequent to that, the following day, we know about a drawing which was pretty morbid with regard to blood and a dead body. iffing and the parents at that time were brought in. and there is where the communication really goes south. at that particular time, the question to be asked is if school officials were in possession of that knowledge, should they have mandated this child was removed from school? should they not, withstanding the parents' objections, say, you're taking him home, he's not staying here. i think any investigation into the school will be predicated upon whether they actually fulfilled their responsibility to act reasonably, responsibly, and appropriately under the circumstances, knowing them to be at that particular time. >> prosecutors aren't ruling anything out at this point, but listen to school officials and what they say about the situation, take a listen. >> i want you to know that, you know, there's just -- there's been a lot of talk about the student that was apprehended. that he was, you know, called up to the office and all that kind of stuff. no discipline was warranted. >> no discipline was warranted. they're saying that, look, this kid did not have some kind of history legally, joey. what would prosecutors be looking at here? >> yes, two tracks. number one, i think there are a lot of people who disagree with the superintendent. when you're talking about a 15-year-old, what record should he have? should he have a record stemming back since birth? a record when he was 10? the fact is they were possessed of information as the school at that particular time. there's indication, if you're searching for ammunition, that's problematic. if you have a picture with dead people on it, that's problematic. with blood, et cetera, and bullets. that's a concern. you don't have to look back to determine that there's some extensive reason to do something. from a legal perspective, two tracks. the one track is the criminal track. i don't see criminal culpability for the school but i see more of a negligence. civil, what's the difference? criminal affects liberty, it's about prosecuting people. civil court is about monetary damages. any one of these parents would say, take your money, give me my child. but that's what the criminal justice process and the law process has, a civil avenue. i would expect that that school will be sued and they will be deemed to have determined that, did you act reasonably under those circumstances? a lot of people will say they did not. >> and we will continue to follow it all. joey jackson for us once again. really appreciate it. >> always, thanks, paula. a republican congressman is facing fierce criticism for his pro-gun tweet just days after the michigan tragedy. thomas massey posted this photo on saturday showing what appears to be his family gathered around the christmas tree, all holding firearms, as you can see there. the caption reads, "merry christmas, p.s., santa, please bring ammo." gun violence activists responded with a picture of his teenaged daughter, who was killed in the parkland shooting in 2018. he tweeted, since we are now sharing family photos, here are mine. one is the last photo that i ever took of jamie. the other is where she is buried because of the parkland school shooting. now the michigan school shooter and his family used to take photos like yours as well, he wrote. here at cnn, suspended anchor chris cuomo is no longer employed at cnn. his termination was announced saturday. going into effect immediately. the move comes after documents from the new york attorney general showing cuomo effectively worked as an unpaid aide to his brother, then new york governor andrew cuomo, as he faced sexual harassment allegations. cnn's brian stelter has more from new york. >> reporter: hey, there, yes. this is sending shock waves across the television news world. chris cuomo was one of the most prominent anchors here on cnn, but he has been terminated, and it all really stems from the sexual harassment scandal involving his brother, the former new york governor, andrew cuomo. here's the statement from cnn saturday night, announced in the news, saying, cuomo was suspended earlier this week pending further evaluation of new information that came to light about his involvement with his brother's defense. we retained a respected law firm to conduct the review and have terminated him effective immediately. while in the process of that review, additional information has come to light. despite the termination, we will investigate as appropriate. reading between the lines, cnn management retained a law firm to conduct its own investigation. and whatever that law firm found was apparently enough for cnn boss jeff zuk tore take action on saturday. i reached out to chris cuomo, here's what he said in a statement. he said, this is not how i want my time at cnn to end, but i've already told you why and how i helped my brother, so let me now say, as disappointing as this is, i could not be more proud of the team at "cuomo prime time" and the work we did as cnn's number one show in the most competitive time slot. chris cue wsaying, i will miss all and that group of special people. cnn is not commenting. number two, how will viewers react? there were many chris cuomo fans frustrated by the suspension and wanted to see him back. however, at the same time, there were many cnn staffers who were very angry at chris cuomo for the way that he enmeshed his personal and professional lives. the way that he was working with new york governors aides in order to try and help his brother survive the sexual harassment scandal. that kind of detail is what came out in the text messages and the sworn testimony that was released on monday. monday led to tuesday's suspension. now to saturday's termination. right now we do know cuomo's staff will not be affected. chris cuomo's team will remain at cnn. there will be a new 9:00 p.m. show at some point in the future. ultimately the most important detail here is about journalistic ethics and standards. about having standards and practices and making sure that the cnn brand is not affected by any single person's conflict of interest. international travel plans have been thrown into turmoil this holiday season as countries around the world rush to stop the spread of the omicron variant are many of the new travel restrictions are aimed at arrivals from southern africa where the new variant was first detected. the u.s. will impose new rules on monday that single out arrivals from eight countries in southern africa. you see them there. similar restrictions in the uk also begin monday. and many of those african nations are now lashing out, saying the new restrictions unfairly target african travelers. the mayor of rio de janeiro announced on saturday that he was reluctant -- he reluctantly is canceling new year's eve celebrations because of the health risks. in rome, police are enforcing a new outdoor mask mandate as shoppers fill the city's shops and streets. in bethlehem, a towering christmas tree was lit in manger square amid uncertainty over whether international visitors will be able to attend. for the second straight day, south africa reported more than 16,000 new covid cases. that's four times what it was a few days ago. live in johannesburg, especially troubling here obviously is the speed at which it seems to be spreading. and yet perhaps some optimistic news from south african authorities today? >> reporter: that's correct, paula. a mixed bag here. first, the fact that now 16,000 cases appears to be the average every day that south africa is reporting of covid-19. and you add to the beginning of this week, south africa was averaging about 4,000 a week. in three, four days, the cases have quadrupled. and the concern here is that many of these people were unvaccinated. the president announced that the rate of hospitalization is not increasing at an alarming rate. he says that even though it still needs research and data to ascertain that, early indications from data from here, health authorities in south africa, indicate even though the omicron variant is more transmissible, it may not lead to as many hospitalizations, promising because it may not lead to as many deaths. but early days. they're still not ready to say that definitively, because severe disease takes time to manifest. that's what the experts at south africa's national institute of communicable diseases say. so they just can't say definitively yet because south africa has just entered its fourth wave. despite the president's optimistic spin, an adviser in his own ministerial covid task force says south africa needs to prepare for a surge in hospitalizations and possibly look at -- look up the supply chain. there's a whole lot that is still not known about the omicron variant. again, the president also going back to what you were mentioning, travel bans against south africa and neighboring countries, zimbabwe, namibia, botswana. he said it's a slap in the face of south africa and southern african nations and africa as a whole. he repeated something u.n. secretary-general anthony guterres said, punishment for warning the world of this new variant of the coronavirus. >> it was interesting to note, in fact that they did praise south africa, yet i want to ask you what the plan is now for south africa in terms of the low vaccination rate. are there signs they might have some success in getting more people vaccinated? >> reporter: so there are people who are hesitant, for whatever reason, either because they have consumed misinformation. one pharmacist i was speaking to yesterday told me in the last 18 to 24 months, misinformation and conspiracy theories have won, science has lost. people were hesitant because they have consumed some things from the internet. there's conservative american talk shows and commentators who are quite influential here in south africa. and that makes its way into the general population. the government is encouraging south africans to get vaccinated. in fact, it has started a vaccine mandate to make it mandatory for some people to get vaccinated if that will provide some protection. so it's still going to be a difficult uphill task for them to convince these people who are hesitant or anti-vaxers. >> many challenges, not just to get people vaccinated, but obviously on the continent of africa to actually get those vaccines in the country. less than 7% of the continent is fully vaccinated. larry, appreciate the update. u.s. intel has a new warning about a potential russian invasion of ukraine. coming up, what u.s. president joe biden is saying about the troop buildup ahead of a russia summit. the pope is in greece to draw attention to migrants in the mediterranean, but he also has a warning for european leaders. i just have to ask. does my aveeno® daily moisturizer really make my dry skin healthier in one day? it's true jen. really?! this nourishing prebiotic oat formula moisturizes to help prevent dry skin. one day? for real! wow! aveeno® healthy. it's our nature.™ i gotta say i'm still impressed. very impressed. new daily moisture for face. everything you love for your body now for your face. and tonight's winning numbers are 18, 18 55, 39, 71, and 43 we won! yes! noooo... noooo... noooo... quick, the quicker picker upper! bounty picks up messes quicker and each sheet is 2x more absorbent, so you can use less. i'll hold onto that. bounty, the quicker picker upper. a russian military buildup near ukraine is bringing new warning from u.s. intelligence. the kremlin could be ready to invade within months. moscow insists that's not going to happen, but a potential russian attack is said to be on the agenda for tuesday's summit between the u.s. and russia. cnn's joe johns has this look from washington. >> reporter: white house press secretary jen saki putting out a statement indicating, as her counterpart at the kremlin already had, that president biden and vladimir putin will have their big telephone call on tuesday on video and one of the major topics to be discussed will be the tens of thousands of russian troops massing on the ukraine border. that statement says in part, president biden will underscore u.s. concerns with russian military activities on the border with ukraine and reaffirm the u.s. support for the sovereignty and intelligent of ukraine. so one of the big questions is whether putin is planning on invading ukraine. the answer to that cannot be known. the president on departure to camp david this weekend was asked what he would do if russia invaded ukraine. he did not answer the question, but he did say this. >> we've been aware of russia's actions for a long time. and my expectation is that we're going to have a long discussion with putin. >> do you see that putin's red line on ukraine? >> i don't accept nine's red line. >> reporter: one of the reasons it's so difficult to figure out what's going on with the russian troops is according to a u.s. intelligence report, they're being moved around in a way so as to obscure their motivations. pope francis is heading to the greek island of lesbos where he's set to meet with refugees in about a half hour. it's part of a five-day trip to cyprus and greece to highlight the plight of migrant in the mediterranean. saturday the pope met with greek leaders in athens. in the birthplace of democracy he warned about the rise of authoritarianism and populism around the world. travel restrictions, lockdowns, and canceled plans. coming up on "cnn newsroom," we take a look at how countries around the world are trying to slow the spread of the omicron variant. ndry sanitizer kikills 99.9% of bacteria detergent alone, can't. dog barks you're right bunker, the medicare enrollment deadline is almost here. if you're on medicare and you want to explore your options, the deadline to enroll is december 7th. so, you should act now. were do i find the right medicare plan?

>> reporter: paula, this country is trying to ramp up its booster campaign to basically what it was like at the beginning of the vaccines, when everyone was getting their very first shot. already gps, doctors here, are being told to put aside any nonemergency care, delay appointments, put all their staff and focus and resources into getting these boosters done. it is absolutely a priority for this government. and it's their tool that they believe they'll be able to use against the omicron variant. across the globe, people preparing for what scientists might be able to tell us in a few days. take a look. the omicron variant has put the world on edge, triggering new travel bans and lockdown measures. more than 35 countries have reported cases of the coronavirus variant. doctors and scientists are racing to gather data to determine if it's more transmissible, causes more severe illness, and whether it could impact the efficacy of vaccines. >> from the early reports that we have, starting with the province where it was first observed, then across the provinces of south africa, we do think it is quite infectious, quite transmissible. it is something to worry about, certainly. we didn't want to see another variant emerge and spread around the world at this stage of the pandemic. certainly not what we wanted. but we're not entirely surprised. and i think we're much better prepared to handle it. >> reporter: but many countries are taking no chances. in germany, chancellor angela merkel announced a nationwide lockdown for all unvaccinated people. italy imposed mask mandates in rome and sicily ahead of the holidays. ireland closing nightclubs, imposing a 50% capacity cap for indoor events. rio de janeiro canceled new year's eve celebrations after brazil detected its first omicron cases. south african scientists first detected omicron. covid-19 cases in the country nearly quadrupled between tuesday and friday, passing the 3 million mark for the first time since the start of the pandemic. 70 to 75% of the cases sequenced in south ka in november were confirmed omicron variant. health officials continue to underscore how important it is to get vaccinated and boost it against covid-19. in the uk, prime minister boris johnson received his booster and urged residents to do the same as soon as possible. >> the target that we've set ourselves is to offer a booster to everyone eligible by the end of january. and as with the first jabs, we'll be working through people by age group, going down in five-year bands. >> reporter: while it may be a few more weeks until scientists know more about omicron, the world continues to act fast to fight the latest obstacle in the coronavirus pandemic. while we wait for scientists to tell us more about whether or not omicron is more transmissible, if it has more severe disease, if it's able to evade some of our vaccines or make them less capable to fight it in any way, we're still waiting for that information. but everyone's still relying on vaccines and booster jabs as being that main layer of protection. but at the same time, what we're watching here is countries watch out for their own, do their individual choices and individual actions, but reality is, it's just as the world health organization has said over and over again. we are not safe until everyone is safe. you have to think about the developing world in these situations and wonder, do they have access to booster jabs? >> yeah, it is a good question. a lot of challenges in the weeks and months ahead. salma, appreciate the update. as you heard, germany is also cracking down on the unvaccinated. last hour i spoke with the chief europe correspondent for "politico." i asked him what will happen if tougher measures don't work? >> merkel hinted at this last week in other remarks that she made. and i think she was looking towards the south, towards austria, which people might remember recently introduced a vaccine mandate. and she said that even though she's leaving office, she's leaving the german parliament as well, that she would support a vaccine mandate because it just doesn't look like the measures that they've used so far and that they've recently announced are going to work to convince this 30% of the german population that's not vaccinated to get the shot in the coming weeks. >> that is a significant proportion, especially when you consider waning immunity among others who are vaccinated and who need to get out there and get their boosters. in the near term, though, even if some of these measures work, what are the immediate challenges facing the health care system there right now? >> well, unfortunately, we're seeing the hospitals fill up. we're seeing the intensive care units in particular get quite full. i think a lot of people are worried that as we head into the holiday season in the coming weeks, that germany's going to be facing a full-blown crisis in the hospitals. and the question is whether these lockdown-lite measures for people who aren't vaccinated are really going to have the necessary effect. a lot of politicians are already admitting now that tougher lockdown measures are probably going to be necessary. and even the public seems to have come to terms with that. >> in talking about the omicron variant, it once again highlights the need for more genomic sequencing. this is the scientific process that identifies covid-19 variants that may be emerging. it's like an early warning system. it's a key weapon in containing the spread of the virus. but as cnn's scott mcclain reports, many countries lack the resources to properly conduct this type of research. >> reporter: in the past few months, the philippines has seen record covid case numbers. and as officials try to contain the virus on the streets, inside this lab in davao city, they're fighting on a different front. >> the first thing is you have to know your enemy. for us to know our enemy in this pandemic, we have to sequence it. >> reporter: in the battle against covid, the lab has the artillery it needs to sequence the virus. this tiny machine. the problem is that it can barely afford the ammunition. the chemicals to actually make it work. they cost about $900 for just a couple hundred test samples. in a given month, they say thousands are needed to fully track the virus. >> recently we started a crowdfunding campaign. and so far we raised around 400 euros. in the philippines as well, $1,000 is like two people's monthly salary. so it's not insignificant. >> reporter: the relatively small funding gap is a big reason why developing countries are lagging so far behind in identifying covid-19 variants that might be more deadly or more transmissible. in the west, labs like the uk's sanger institute are sequencing the virus on a huge scale, using multimillion-dollar machines like these. according to the covid variant database, the biggest contributions are coming from the richest countries. some countries haven't sequenced any any genomes at all. >> we don't get to do sequencing in many parts of the world, then definitely we're missing out on possible variants that are emerging. >> reporter: we know how rapidly new variants can take hold. the delta variant first emerged in india in april and was the dominant variant worldwide by mid-july. omicron, the new variant first spotted in south africa, was declared a variant of concern in record time and is predicted by some experts to become the dominant strain in the days ahead. its emergence highlighting again the importance of realtime virus surveillance. getting the necessary technology out to all corners of the globe is part of the challenge. and this company an hour north of london thinks they have an answer. >> the technology to sequence the virus in remote labs around the world is being manufactured here on an industrial scale. it's small and relatively inexpensive. the challenge has been getting governments to actually use it. >> these systems all plug and play. if you're a 16-year-old high school student, you can run this platform. it's that easy to use. >> i wonder, why aren't more countries using it? >> it's a confluence of regulations, governments, lack of awareness. we've been slow to fully understand that we need to look at the variants. but if we got a vaccine escape variant, things would change dramatically overnight. >> reporter: in the philippines this lab won't be doing large scale surveillance any time soon without a massive influx of cash. but they have proven with a tiny piece of technology that even small-scale operations can contribute to covid sequencing, helping us all stay one step ahead of the virus. coming up, a volcano erupts with deadly consequences. its ash cloud so enormous and high, planes are getting warnings. the latest after the break. emerge tremfyant®. tremfya® is approved to help reduce joint symptoms in adults with active psoriatic arthritis. some patients even felt less fatigued. serious allergic reactions may occur. tremfya® may increase your risk of infections and lower your ability to fight them. tell your doctor if you have an infection or symptoms or if you had a vaccine or plan to. emerge tremfyant® with tremfya®... ask you doctor about tremfya® today. i don't just play someone brainy on tv - i'm an actual neuroscientist. and i love the science behind neuriva plus. unlike ordinary memory supplements, neuriva plus fuels six key indicators of brain performance. more brain performance?
