>> reporter: well here at zuckerberg san francisco general hospital, there are 40 special isolation rooms. and today we looked inside one of them. known as an airborne infection isolation room, this is where any future patients diagnosed with novel coronavirus will be treated at zuckerberg san francisco general hospital. what's unique about the room is that it has negative air pressure, designed to keep the novel coronavirus and any other infectious diseases from spreading to other parts of the hospital. >> prevent the spread of virus. because when the pressure is negative, it keeps the air in the room exhausting out, rather than going out into the wall hallway. >> it has two doors and a special entry room where hospital workers can put on face shields and gowns and other protective equipment. they also put up these signs at the entrance, warning those who recently traveled outside the u.s. and have fever or cough to alert health care staff immediately. it's not just hospitals preparing. schools are also beefing up protections for students and teachers. >> we recently got direction from our public health officers that any student or staff who have been in china since february 2nd and returned february 2nd or later should be staying home for a 14-day quarantine period. >> reporter: and oakland unified school district is following the same protocol. in san jose, the school district says it's keeping a close eye on students with a high fever and plans to isolate them immediately and send them home to recover. here at sf general, a team meets every single day to coordinate a potential response to the coronavirus. you have to remember this is an emerging health threat, and the cdc is constantly change its directives. reporting live in san francisco, marianne favro, nbc bay area news. >> marianne, thank you. now you can keep track of the latest coronavirus cases right there on our website. you see this global map here. it includes the map that has all the confirmed cases. we posted it at nbcbayarea.com. an historic moment in washington. today the u.s. senate acquitted president trump with a near solid party line vote. one by one senate members stood to record their votes. it was never close to the 2/3 needed to convict. chief justice roberts read the acquittal. the most dramatic moment came from republican senator mitt romney, who in an emotional speech raised the issue of his faith and his oath, declaring he would break the gop wall of support. >> corrupting an election to keep one's self in office is perhaps the most abusive and destructive violation of one's oath of office that i can imagine. >> it took enormous courage for senator romney to do what he did. >> and my suspicion was it wasn't so much about president trump but rather about taking the senate. >> though the trial is over, the house may continue to investigate the president's action and pursue a subpoena for former national security adviser john boalt on the. >> hey, hey, ho, ho -- >> this is one of three so-called reject the cover-up rallies held in san francisco. a coalition of activist groups organized them across the nation. protesters claim the impeachment trial wasn't fair because no witnesses or documents were subpoenaed like john boalt on the. they're calling for election and an end to voter suppression. disheartening and violent. vandals target a preschool on the peninsula calling it a ritualistic slaying of animals. robert handa is at millbrae nursery school with details. >> reporter: the millbrae nursery school has been here for 82 years, and the staff says there has never been any kind of violence like this before. the people inside are in a daze, saying to them it has all the appearances of a very brutal, senseless killing. the director of the millbrae nursery school still looking over the chicken coop and bunny hutch where the students learn thou take care of the animals. some time from late friday night to sunday night a person or persons kicked through a side gate and broke windows and five chickens were cut open and killed in a ritualistic fashion. >> it wasn't as if they left them in place. they took them all out. they lined them up, and you could see where they were cut open. >> reporter: the scene was so gruesome that the school elected not to tell the 48 students what happened. the children, ranging in age from 2 to 5 years old were told the coop was broken and the chickens were taken away while the repairs were made. parents we talked to were almost beside themselves with rage. >> lined up in a way and gutted out. it's scary. who would do that? who can be sick enough to do something like this? >> reporter: sheriff investigators have confirmed the breaking and entering, but are still trying to determine if the killings were done by human or wild animals, and they say the chickens bodies were scattered around the lawn. the school director still believes this is a crime by a person, and that makes it difficult for anyone here to feel safe. >> the fear is not only are we devastated the violation of our program, but this person is out there. and who knows what will happen next. >> reporter: the school board and parents met monday night and planned more meetings through the week to discuss how to increase security. the sheriff's department will help them with that and also plan extra patrols in the neighborhood. robert handa, nbc bay area news. >> thank you, robert. opening statements today in the murder of nia wilson. her alleged killer had to be led out of court at one point. john lee cowell allegedly stabbed wilson at the macarthur bart station in 2018. today he seemed to question prosecutors' comments, so deputies removed him from the courtroom. the prosecutor, meanwhile, played graphic surveillance video of the horrific attack which was met with sobs in the courtroom. the prosecutor described cowell as coherent and responsible. >> how could you do something to beautiful young women, you know what i'm saying? they didn't do nothing. they don't know him. pure evil. >> the defense attorney for cowell argued he is mentally ill and suffers from delusion, and that there was no motive, dispute or plan roved in the attack. the trial continues tomorrow. a high profile cold case is heating up. this is all about kristen smart, the college student who went missing nearly 25 years ago. search warrants were served at four different locations today. smart disappeared in 1996 while attending cal poly san luis obispo. today warrants were served at two different areas in san luis obispo county as well as l.a. and washington state. the sheriff's department would only say it was for specific items of evidence. smart was from stockton. she was only 15 years old and went missing while returning home from a student. she was seen with another student at the time, but he was never arrested or charged in the case. up next, could your vote get thrown out? we investigate why tens of thousands of vaughs were thrown out two years ago, and we're going to tell you how you can avoid it this year. and take a look. guess who's in town. recognize him? that's keanu reeves shooting his new matrix movie in san francisco. why the location means so much for chinatown. i'm chief meteorologist jeff ranieri. a cool 55 in san jose right now, but i'll show you where 70s, yes, 70s are possible tomorrow. that's coming up in about nine minutes. we tried to get the politicians to deal with the problem. but they wouldn't. so we took it to the voters and forced big tobacco to pay its share of healthcare costs. we fought oil companies for new clean air laws and closed a billion dollar corporate tax loophole to fund public schools. by going directly to the people we got results. that's not something you see a lot of from washington these days. i'm tom steyer and i approve this message. let's make change happen. well, we've heard every vote counts, but our investigative unit found more than 150,000 ballots that were thrown out by local officials here in california. this happened here in the 2018 elections. >> that includes 2500 in san mateo. close to 7,000 in contra costa, and more than 9,000 in san francisco, 11,000 in santa clara county. workers flagged these ballots for various reasons like voting late or double voting. but one of the most common reasons they tossed the votes out is because the signature on the ballot didn't match the voter's registration signature. joining us is stephen stock. >> you actually talked to some of these people. >> that's right. >> you sign your signature. it doesn't match up, your vote gets thrown out? >> that's exactly right. in every county is a little different. when we talk to these voter we got their names, we called them. some of them were shocked and said how did that happen? this was a legitimate vote. this is all meant to try to make the election more secure. an these are only provisional ballot, mail-in ballots. >> how big a discrepancy are we talking about in the sig her? >> well, we talked to one gentleman. he said sometimes you sign real quickly and sometimes i make it really nice. >> i think we all do that. >> and that's what's happening. san francisco, to their credit, has been sort of adjusting for the last six years. every signature, if you go to san francisco and sign, they track it. and if it matches any one of those, then they allow the vote. but other counties are not nearly as vigilant. so if your signature doesn't match, they toss it out. >> so do they call you and tell you there is a problem or how do you find out about it? >> some counties do and some don't. now the law is changing. this year in 2020, they are supposed to call and tell you. some counties will text or email you. you can go online and check anywhere in the state if your vote got thrown out. if it did you can go to the division of elections and say whoa, that was my vote and they have three or four days depending on how soon you contact them to count your vote. >> but if it hasn't and they don't reach you in a certain amount of time -- >> then you're out of luck. >> that's not retroactive. >> we talked to tens of thousands of people who say yes, they contacted me two days after the election was over, after the deadline. >> how many people? >> 162,000 in just 13 counties. >> so big picture, what's the percentage of votes? >> less than 3%. we calculated between 2% and 3% of all the votes that were cast. but i just mention one thing. this could be close for a small election or a referendum. >> sure. >> but don't forget, donald trump won the presidency with 77,000 votes over three states. this is 162,000. just saying. that's a lot of votes and every vote should count. >> plus it's just the whole point of it is the reason you send the vote in is you want your voice. >> you want your voice heard. that's exactly right. >> cleanup your handwriting. >> check your vote this year. this year go online, check your vote. >> good information. >> now if you have a story for investigative unit for stephen specifically, you can reach him by calling 888-996-tips or visit our website, nbcbayarea.com/investigation. this was supposed to be us. today was a perfect day for the super bowl parade. slight problem, though there was a parade, but it was in kansas city. temperatures in the 20s, but the chiefs kingdom was red hot. congratulations to them. the chiefs' first victory parade in 50 years. you see the mvp, patrick mahomes right there. our parade route was supposed to be down market street, ending at civic plaza. >> it was beautiful. >> no parade force. this is what we got. the 49er, jimmy g. and the gang clearing out their lockers. it's a tough reality. they signed each other's gear, exchanged hugs and said goodbye, at least for the off-season. most of the players, including jimeny gram lmy garoppolo are t get over that ten-point lead. >> you got to own it. got to be a man. i don't know. just tack it right down the middle in the face and look back at the season. there is a lot of good memories from this year. this team, the players, coaches. it was a great group to be around. i enjoyed every minute of it. a terrible ending, but just got to take the good with the bad. >> you can hear it in his voice. >> well said. so many fans piling on jimmy g. he got beat up by patrick mahomes who is the best quarterback in the league. anthony flores will have much more on the 49ers later in this newscast. we told you about this earlier, that it was possibility. and there he is. san francisco's chinatown the backdrop of a big hollywood film shoot today. you recognize that guy, keanu reeves. the matrix 4 crew in town. and there is keanu too. chinatown leaders say it's good news for the neighborhood. lili tan is live. >> reporter: chinatown leaders say this film shoot could not come at a better time because rumors and misinformation about the coronavirus have really dampened the mood here in chinatown. they figure what better way to dispel the rumors than to see a movie star like keanu reeves walking around. and that he did. he came out of the house of nanking several times, walked down to grasslands, and his fans followed. >> i can't believe. i can't believe. >> reporter: matrix fans knew it might be their only chance. >> oh, wow. this is a great day. >> reporter: take jackson street, the story ends. take kearney street, and see if star keanu reeves emerges from the rabbit hole. or in case, the house of nanking, where the matrix 4 was filming. >> i think it's great to get the exposure for san francisco, for chinatown, little italy. looking forward to seeing it in the movies. >> reporter: for chinatown leaders welcomed film crews. >> i'm so glad they're here because that means chinatown is safe. the people for a last couple of weeks are so concerned about safety right here, the coronavirus. >> ding li says rumors about coronavirus have caused chinatown businesses to suffer. but the chance of seeing a movie star every day for the next month might just help change the script. >> that would be amazing. >> reporter: also on the film schedule, helicopters, crashes, and gunfire simulation. drivers can expect a lot of road closures throughout the area until the end of the month. you can find that complete list on our website, nbcbayarea.com. live in san francisco's chinatown, lili tan, nbc bay area news. >> okay, thank you, lili. remember a couple of months ago we saw i'm eating an ice cream. and it was like a teaser that he might be here. and here he is. >> see a pretty good-looking guy. he is aging well. he is like a mirage because he's not on the red carpets a whole lot. but you see him in person, it's like wait. >> maybe he needs extras. >> need three extras in the movies, keanu?
