a safe place. >> and the police had to. >> reporter: the lawsuit also alleges there were at least three other victims in that 9-year-old student's classroom. police say this is a very far-reaching investigation. they're asking anyone with information about this case or any potential victims out there to contact the tip number that's back to you. >> thanks, meagan. people are dying needlessly and it's a highly toxic culture. those are two of the issues that the medical director for d.c.'s fire department cited as reasons she's resigning. her resignation comes less than a year after she was hired to take the post. dr. jullette saussy says she came into the department to reform the city's troubled ambulance service, but she says the department has been too slow to make any progress. d.c.'s mayor muriel bowser says the city is committed to providing proper training and equipment. coming up at 6:15 in this broadcast, pat collins will report on one of the most recent cases cited by the director in her letter of resignation. police say six young children were left home alone. one of them died, and now investigators are looking for some answers. the he was rushed to the hospital

doreen. i can tell you i just got off the phone with d.c. police and they have now located the mother of the six children and they are now questioningu4d÷ her. they will not tell us where she was during this incident. as for the five children who were found in this home, they are in the care of d.c. child and family services where they are reportedly safe and healthy. it was about 7:00 this morning. police and fire arrived at this home and found the dying infant and his five siblings. there were no adults in the home at the time. it was just as neighbors were heading out to school and work. >> very surprising. very surprising that something like that would happen. coming out for work and it was about six cop cars parked outside. no people around. just cops. >> reporter: inside this home, the oldest a 10-year-old. one of those children inside called 911 for help for their baby brother. >> it was before school started, so who knows what the plans were for the day. >> reporter: police are now investigating the death. >> it's just a tragedy. anytime you have an infant that's, you know, involved in a death investigation, it's tragic for everyone. >> reporter: now, police have been going in and out of this house all day today. i spoke with an official with child and family services who tells me that the five children will remain in their care until they complete their investigation and determine that it is safe to hand them back over to their parent or guardian. i asked if they had ever been to this location before, and all they would tell me is that at the time of today's incident, there was not an open investigation. jim, back to you. >> mark. breaking news on the presidential campaign race. new jersey's governor chris christie has suspended his campaign. he

got back from richmond and he joins us with concerns already being raised. >> reporter: as you mentioned, we started our day down in richmond and lawmakers down there selling this as a bipartisan bill, one that has support from both sides of the aisle. back here in arlington county, the board chair put out a statement expressing some concern over immediately widening these lanes behind me, the eastbound lanes of 66 inside the beltway. i have been chatting with some of you over social media, and it seems some of you share those concerns. >> northern virginia is one of the most congested regions in the entire nation, and we are now fixing the most congested road in the most congested region in the nation. >> reporter: as soon as we tweeted the governor's announcement to add a third lane on 66 eastbound from the dulles connector to ballston, you began tweeting back. aaron writing, one lane is not going to end congestion on i-66. 66 is laughable to katie. but the plan goes beyond adding another lane. it's a transformation of the whole corridor. beginning late next year tolling will start inside the beltway. this will affect only lone drivers. there will be no toll for car pools. >> if you are hov today, your ride for free, you ride for free after. let me be clear, all we're offering here is an option to solo drivers who today are prohibited from going on 66 during rush hour. >> reporter: by 2020 that car pool requirement will jump from two to three. >> it may be a done deal, but i intend to fight it. >> reporter: holding an anti-tolling sign, prince william delegate bob marshall says he'll vote against. >> you're going to bankrupt people. people making minimum wage can't even use this road. >> reporter: but those representing arlington residents at the state level, arguably the most impacted, say it's time for the county to change. >> you're going to have to move a little bit with the t, craft a deal that emphasizes transit but allows for this additional lane. >> reporter: and while we were down in richmond, virginia's transportation secretary said an environmental impact study will start immediately when it comes to the widening project. there's a lot of moving parts to this plan. can be a little confusing. i went ahead and tweeted out a little video to explain it a little clearer. you can find it @david culver. >> the results so far suggest the majority of folks who responded say yeah, it seems to be a good idea. turning to our weather now, get ready for a dramatic temperature drop. doug is tracking the conditions and lets us know when

county executive, county executive, mr. baker. >> thank you. good evening. a terrible situation has hit us all very hard in prince george's county. this is a painful situation for the county. to think a person that we entrusted would deliver everlasting harm to our young people, our babies, it breaks our hearts in prince george's county. as a parent of three, i'm particularly taking this hard, as i'm sure most parnts aents at there. we can only imagine who could have to our precious children that we have sent to school and our places in the county because every child in this county are our baby, and it is our job, it is my job, to protect them from predators like the one that we arrested. i'm asking all prince georgians to keep these children and these families in your prayers. our children are precious and we are working diligently to provide them support. the one thing i want to make clear is that this is an ongoing investigation. we're going to be forthcoming with information tonight, but this investigation doesn't stop with this arrest. it doesn't stop with the prosecution of this individual. so we're going to make sure and we're going to make sure when we answer questions tonight that it doesn't jeopardize this ongoing investigation. what i want the people of prince george's county to know is that their government will use every resource to not only follow this case to where it leads, but also to provide the type of support for the families of this tragedy. everything that we have in our power will be at the disposal to use in this situation. i have asked our police working with our state's attorney and the rest of our government to do everything that we can. our school system is taking the necessary steps which you will hear tonight. but i want you to know that we're going to do everything in our power to make sure that this type of situation doesn't happen again. we're going to look at everything, everything. that is why i'm pleased to have our school board chair, dr. eubanks, come up here and talk to you about the things that we have been doing. doctor? >> thank you, county executive baker. on behalf of the prince george's county board of education, i want to deliver brief remarks to deliver a message to the citizens and parents of prince george's county. we know as the elected and citizens of this great county, we too are parents. most board members like myself have children in the public school system. we are brothers and parents and uncles and grandchildren of children in the public school system. we know that when we send our children to school every day, we do it to make sure they get a world-class education and that the opportunities available in this great nation and great world become available to them. we send them to school, and we expect them to be safe. in fact, for far too many of our students, school is a safe haven away from so many of the other violence that is perpetrated throughout our society. so when our safe haven is violated and it is done so in such a vial and painful way, we are deeply disturbed. we are evermore committed and vigilant to working to make sure young people who enter our doors each day leaves safely and unharmed. we will commit to many things, but i will point to three. first, as mentioned, we will fully and 100% cooperate with law enforcement. any and everything that is available for us in prince george's county public schools will be available to law enforcement officials in this important investigation. second, we will remain committed to the families and students who have been victimized by this vial incident until they are fully recovered no matter how long it takes. and, third, we will fully investigate internally whether the many policies, programs, and safeguards that we put in place were properly implemented and whether we need to redouble our efforts with new policies, safeguards, and procedures to make sure that we minimize the happening again in the future. i'm going to turn the floor over to our ceo, dr. maxwell, who will give more details about the steps we're taking. thank you. )ñ dr. eubanks. thank you all for being here. i have a few brief remarks as well, and after this is all over we'll be available for questions. first, let me say as a father, a grandfather, and an educator that has dedicated my entire life to the education and safety of students all across the state of maryland, my heart goes out to the families and victims at judge sylvania woods elementary school in prince george's county and the entire glenarden community. i, like many of you, were shocked, appalled, disgusted, and disheartened by the allegations that a former prince george's county public school employee harmed students and especially vulnerable children. i want to be very clear that this district is dedicating every resource we have avla to help our students, families, and staff. tonight i will outline for you the steps we are taking to support judge sylvania woods elementary school and outline how we will foster a safe and secure environment for all children in prince george's county. prince george's county public schools has and will continue to fully cooperate with our law enforcement partners. throughout the duration of this investigation. i want to publicly thank the chief and county executive baker for their support as the investigation continues. as soon as the allegations were confirmed a eed and the arrest made, we immediately took steps to assist the students and families. first, there was a meeting with parents at judge sylvania woods elementary school, and we have provided counseling and psychological support for request. we will continue to keep this support in place as long as it is needed at the school. second, we reviewed our administrative procedures and policies on abuse and suspicious activity with the entire staff at judge sylvania woods elementary school. third, we have scheduled a parent meeting for thursday at 6:30 p.m. at judge sylvania woods elementary school to outline additional measures we will take as a school system to address the safety and security of students. in this meeting many of the representatives from some of the agencies here tonight will also be present to report on resources available and the status of the investigation. this situation has shown us that what we were doing at judge sylvania woods elementary school to support students is necessary for the entire public school community. we have established a parent and student safety hotline. the hotline will be available for anyone to report suspicious for questionable behavior. each and every call investigated. the number for the parent and student safety hotline is 301-618-8342. once again, 301-618-8342. the line will be open for calls begin tomorrow morning. our professional school counselors will conduct classroom guidance lessons for all students which will include differences between appropriate and inappropriate physical contact, personal body safety rules, and when to use them and how to identify trusted adults to whom they can report when they feel unsafe. this evening at the conclusion of this, i'll be sending a directive reinforcing to all principals that they must meet with all school-based personnel to review the august 2015 training and the contents october 2015 memorandum we sent to all employees. the training and memorandum contains the process and procedures required for reporting suspicious behavior. during our already scheduled systemic principals meeting next week, our office of general counsel will review the laws, policies and procedures related to our employees' obligation to report suspicious behavior. finally, i am immediately convening a task force of internal and external partners to review our current policies and procedures and identify areas of immediate improvement that are possible. we will also consult with national experts in this field to ensure that the task force recommendations are in line with best practices from across the country. as stated earlier, this district will use all of its resources possible to foster a safe and supportive environment for all students and families. it goes without saying that these type of acts are intolerable and wholly unacceptable. i'll stuwinski to update you on the criminal investigation. >> thank you, dr. maxwell. i'd like to begin by giving you a brief overview. monday we convened a conference call with the impacted jurisdictions and concerns. tonight with us is chief o'donnell from the glenarden police department, chief stanley johnson of the maryland park police, and with us also in spirit certainly are members of the baltimore field office of the fbi who were tragically called away to assist our colleagues in harford county this evening. as it stands now, there aren't new dramatic developments. i can say there are seven victims, there are 11 in the aggregate, but seven of them were abused by this individual directly. we have interviewed over 18 children and more than two dozen families. that's being done as i discussed on monday by a task force comprised of members of the agencies i have just spoken about, prince george's county police detectives, and members of the federal bureau of investigation. in addition to special agents of the fbi, i would like to point out that the fbi has drawn resources from around the nation in order to aid the victims. at this point we have begun to charge additional counts against this individual, but the focus of the prince george's county police department and our colleagues in this investigation is on the additional victims, so we're looking to identify those children who have been victimized so we can reach out to them through the county social services, through the school system, and provide them with the support that they need to deal with this terrible, terrible crime. beyond that i would just like to say that the men and women of the prince george's county have worked tireless. i thank them for work. the final key partner is our state's attorney. she and her staff have been involved since the very beginning. it's my privilege to introduce her for some remarks. >> a live news conference from prince george's county as school and county officials and law enforcement officials talk about the child pornography investigation under way at judge sylvania woods elementary school. there is one man charged, and police -- we just heard the police chief say they have identified at least seven victims and interviewed 18 children now, and the fbi is now involved. so there is more to come on this. >> noted that their focus is on any additional victims who may be out there which they suspect may be the suspect. 22 years old, deonte carraway, and there is much more on this story to beea bring it to you. >> indeed, we will. doug is back with more about our weather that's about to turn seriously cold. >> it is. and it's happening during the weekend. that's actually some very good news, saturday and sunday, because most of us for the weekend, we don't have to go anywhere. so if you don't have to be out in it, maybe just stay home by the fire, stay home where you know you have some heat. take a look at the feels-like temps. tomorrow it will feel like single digits to the teens. that's tomorrow. friday we get back into the mid-20s. yeah, mid-20s. saturday we are in the single digits all avenue. we fall below zero saturday night into sunday and then sunday is just one cold day too. we've got the cold for sure. 32 degrees right now. temperatures dropping through the 20s, but again the wind is a factor. wind chills already in the teens in many locations. current numbers, 25 in gaithersburg. 27 dulles. 31 down towards camp springs. and we have tracked a few snow showers. warrenton, southern fauquier george county and charles county all reporting some flurry activity or some snow showers. that may continue, could make things just a little slick down there. but everybody gets in on the cold. breezy and cold tomorrow. the windchill between 10 and 15-all afternoon. actual temperatures 26 to 30 degrees. that's a cold day. but it gets a whole lot colder for the weekend. 34 on saturday. rather for friday. 34 on friday, that's the warmest day we have. here comes saturday starting off at 28 degrees on saturday, but then temperatures actually drop during the day. again, very cold saturday. very cold on sunday. an overnight low of 9 on sunday morning. and then we get warmer. rain or snow on monday but then maybe changing to all rain on tuesday. that's a system we have to continue to watch very closely. >> thank you, doug. another sign tonight plans for the purple line are moving forward. the feds are pumping hundreds of millions of dollars into the project. the modern streetcar connects
