captioning sponsored by cbs >> glor: deadly storms strike the heart of the country. homes swallowed up by floodwaters were knocked down by a tornado. >> oh, my goodness. >> glor: also tonight, a former deputy defends his actions during the florida school shooting. the president escalates his criticism. >> i really believe i'd run in even if i didn't have a weapon. >> glor: what monica lewinsky is now saying about her relationship with president clinton. an employee of the c.d.c. disappears without a trace. every public schoolteacher in an entire state on strike and no end in sight. and toneman douglas scores an upset win when it's needed most. >> this wasn't for us. this was for the 17 victims. we played for them.

this is the "cbs evening news" with jeff glor. >> glor: good evening. we're going to begin tonight with first defense from a man who was blamed in part for not stopping the parkland, florida, shooting. former deputy scot peterson has taken a public beating over his failure to confront the florida high school shooter. now one-time school resource officer of the year is speaking out, explaining what he did and did not do. here's manuel bojorquez. >> he wasn't a brave guy. under pressure he choked. >> reporter: the president again today criticized former school resource deputy scot peterson for not entering the bidding where the shooting happened an confronting the gunman. peterson is now fighting back inch a statement his attorney said the first call peterson received was of firecrackers and not gunfire. when he actually heard shots, he believed they were coming from outside and consistent with his train, mr. peterson took up a tactical position between two

buildings. a raid yes transmission about a possible victim by the football field "served to confirm mr. "p.t.i.'s" belief that -- peterson's belief that the shooter or shooters were outside." but with over 100 rounds fired over six minutes, jeff bell questions peterson's claims. >> with that information, you know where those rounds are being fired from, you better get your butt inside that building. there are plenty of circumstances and past scenarios where shooters have simply just given up because they saw a uniformed police officer making entry. >> reporter: the sheriff's office said it was also investigating unconfirmed reports that three other deputies stayed outside and whether two of 16 calls about suspect nikolas cruz's behavior before the shooting were properly handled. governor rick scott has now called for a state investigation, and more than 70

republican state lawmakers signed a letter urging the governor to suspend sheriff scott israel. the sheriff refuses to step down. >> i can only take responsibility for what i knew about. >> reporter: student activists and their supporters are keeping the focus on pushing for stricter gun laws. survivors returned to campus yesterday ahead of the start of classes. >> i want to walk into school with my head held high because i know that's what they wound have wanted. >> reporter: classes are set to resume wednesday with half school day and grief councilors on hand. teachers have already been allowed to return to the campus to prepare. jeff? >> glor: manny, thank you very much. the national debate over how the protect school kids took place at the white house as the president met with state governors. here is white house correspondent and "face the nation" correspondent margaret brennan. >> i really believe i'd run in, even if i didn't have a weapon. >> reporter: president trump insisted he would have barged into the parkland school to save

students under fire. >> i say the only way you stop it is retribution. i don't think you'll stop it by being kind. >> reporter: the president urged a roomful of governor to take up the n.r.a.-supported idea of arming educators and used a golf analogy to describe those who perform well under pressure. >> how come some people make the four footer and some people can't take their club back. >> educators should educate. they should not be foisted upon this responsibility of packing heat in first-grade classes. >> reporter: washington democratic governor jay inslee said teachers are not interested in firearms. >> i suggest we need a little less tweeting, a little more listen, and let's take that off the table and move forward. >> reporter: the president held up programs in states like texas and arkansas as a model, yet on the federal level, republican congressional lead, remain reluctant to craft laws requiring arming school staff. other initiatives like raising the age limit for weapons purchases and banning assault rifles also faced long odds in congress.

leaving state governors to act faster and president trump urged them not to fear the gun lobby. >> reporter: don't worry about the n.r.a. they're on our side. half of you are so afraid of the n.r.a. there's nothing to be afraid of. if they're not with you, we have to fight them every once many a while. that's okay. >> glor: margaret, the president did mention raising the age to purchase firearms. any development there? >> reporter: well, he has mentioned that in the past, but today he did not reiterate the call to bump up the age of purchase to 21. but the white house says he does still support the concept and denies that a meeting on sunday with the head of the n.r.a. softened his stance. a bipartisan group of lawmakers will be here on wednesday. jeff? >> glor: margaret brennan just made her debut on "face the nation" yesterday. margaret, thanks very much. there was an anxious watch along the ohio river tonight. much of it is above flood stage with more rain on the way later this week. this follows weekend storms including tornadoes that ripped through the south killing at

least five people. a disaster has been declared in 18 counties in indiana, including jefferson, across from louisville, kentucky, and that's where david david begnaud is tonight. david? >> reporter: jeff, where we are tonight, the ohio river is actually the barrier, the border between indiana and kentucky. the river has swollen so much that it is starting to flood nearby creeks and rivers, and it's causing rural flooding. in fact, we're boating right now on what is a street in clarksville indiana, not far from here in louisville, kentucky, they had ten inches of rain in five days. that makes it the wettest february on record. in fact, in louisville, they've got 16 pumps, which have already pumped out 2 221 billion gallons of flood water. that's enough floodwater to fill 210 million bathtubs in america. south of here there were tornadoes over the weekend, and that were deadly. it was an ef-2 tornado that took out that window.

here in clarksville, tennessee, saturday night at 9:00. the winds were nearly 125mph when that tornado took off most of the roof and this side wall. no one was hurt, not far from here in logan county kentucky, 79-year-old dallas jane colmes was killed when her house fell on top of her. she was going to celebrate her 50th wedding anniversary with her husband in a few months. he survived. throughout this neighborhood, the tornado hopscotched, damaging more than 80 homes and vehicles, as well, including this one, brand-new, had just come off the lot and was sitting in the owner's driveway for just four hours. more heavy rain is expected in arkansas and tennessee. in fact, in that area they could see more tornadoes. jeff, the good news, where we are, the ohio river is krefted. here in clacksville, indiana, we're told residents should be able to get back into their homes. it may not be for another 7 to 14 days. >> mason: david begnaud, thank you very much. now we move to a mystery.

abemployee of the c.d.c. in atlanta has disappeared without a trace. he hasn't been seen in two weeks. omar villafranca is following the investigation. >> reporter: police were back in timothy cunningham's northwest atlanta neighborhood today looking for anything that helps answer why the 35-year-old has disappeared. cunningham, a harvard-educated epidemiologist at the centers for disease control left work sick on february 12th but never returned. after not hearing from their son for two days, cunningham's parents drove from maryland to atlanta. they found his wallet, his car, and pet dog still at his home. darrell cunningham is timothy's father. >> we're hopeful with the money and the press associated with that, it could perhaps bring to memory something that someone may have forgotten. >> reporter: in statement, a c.d.c. spokesperson wrote, "dr. cunningham's cleanings and friends at the c.d.c. hope that

he is safe. we want him to return to his loved ones and his work." worried friends of cunningham have joined in to help. they've actually started canvassing the area and putting up flyers like that one there. they also started a gove page to increase the reward for information. their goal is $10,000. jeff, they've already raised more than $20,000. >> glor: a story we will keep following. omar villafranca, thank you very much. some disturbing numbers came out today concerning teens and depression. one in five will experience it at some point during adolescence. now the american academy of pediatrics is calling for every child 12 and older to be screened. dr. tara narula is here with more on this. tar,a, what do you make for thi? >> there could not be a better time in our society for putting children's mental health at the forefront. 20% of adolescents report a history of depression.

50% are undiagnosed. of those that are diagnosed, only half receive the proper treatment. pediatricians are thrust into the forefront because of mental health shortages and because of the barriers of access to adolescents to mental health services. that's why this discussion is happening here. they need to be trained and empowered to take on this role. if children do not get the appropriate care, they are set up for social problems, school problems, family problems, substance and back to you -- abuse and suicide. >> glor: this means a new role for doctors. >> it does. this has been recommending before. this is about giving pediatricians more guidance. it says children should be screened starting at the age of 12 yearly for suicide, depression, mental health issues. they should also have time alone with the adolescent. they should also spend time with the parents to identify and discuss depression risk factors and what symptoms might look like, create an action plan, a treatment plan, and a self-harm

plan, a safety plan should the child exhibit signs of self-harm. >> glor: a lot of talk about social media and the time kids spend on their phones is. that factor in depression? >> it is. the research has shown us that social media internet screen time does play a role in increasing the risk of suicide and depression. we leaving that face-to-face interaction that's so important. >> glor: tar, yeah thank you very much. in syria the assad regime has ignored a u.n. ceasefire declared saturday. there is evidence of a new gas attack outside the capital. charlie d'agata tonight has the latest on this. >> reporter: on this second day of the ceasefire, air strikes and missiles continued to pout ghouta. the bombing has been strongly condemned around the world, but the syrian regime and their russian allies seem deaf to the criticism. the famed while helmet civilian rescue teams worked frantically to save who they could. and medics today said they

treated children who showed symptoms consistent with a chlorine gas attack. we've been keeping in touch with the family of ten-year-old noor and her eight-year-old southeaster nala. she suffered a gash on her forehead when a piece of shrapnel from a nearby explosion tore there their living room. today we spoke with their mother, shamza khatib. have you seen any change since the ceasefire was announced? >> the planes target us. >> reporter: so there were more air strikes in. >> yeah, and bombs, more than 20 bombs. >> reporter: activists say more than 500 people have been killed since the bombing started. the russians say the ceasefire doesn't apply to the targeting of those they consider terrorists. that's no solace to the residents still trapped there. charlie d'agata, cbs news, london.

>> glor: for the first time tonight we're seeing images of one of four u.s. soldiers killed by islamic militants last october in the african nation of niger. david martin reports the video was captured by national geographic cameraman for a report airing tonight. >> reporter: coming just one month before his death, the small talk in makeshift shop between sergeant ladavid johnson and one of his commanders is especially poignant. >> finding stuff to do like making sure my truck is good, making sure my generator is good, like regular maintenance on the daily. >> reporter: johnson was the mechanic for a special forces team that trained nigerian soldiers, and according to joint chiefs chairman joseph dunford accompanied them on low-risk missions. >> they were authorized to accompany nigerian forces when the prospects ofenmy contact was unlikely. >> reporter: the enemy, an offshoot of al qaeda, was described to american commanders by the chief of niger's special places forces. >> these guys are very mobile.

they move on motorcycles, land cruisers. any time we have an encounter with them, we try. >> reporter: special forces set out on a routine patrol but were give an second mission to check out a camp used by a suspected terrorist who had fled across the border into mali. that change of plans significantly increased the chance of enemy contact, even if the terrorist was no longer there. retired brigadier general donald bolduc is a former commander of a special operations in africa. >> i would still consider it a very high-risk mission in that there's still intelligence that isn't definitive on exactly what the enemy situation is there. >> reporter: as they returned from that mission, stay topped at this village for water. shortly afterward they were ambushed and four soldiers killed. ladavid johnson's body was found two days later riddled with bullets. which commanders approved that more dangerous mission and why is part of an investigation which was supposed to be completed in january but has

only now reached the secretary of defense. jeff? >> glor: david martin at the pentagon. david, thank you. up next, why every public school in an entire state has been closed for three days and counting. so i feel lighter. try metamucil, and begin to feel what lighter feels like. and back pain made it hard to sleep and get up on time. then i found aleve pm. the only one to combine a safe sleep aid... ...plus the 12 hour pain relieving strength of aleve. i'm back. aleve pm for a better am.

health shierns increases. >> i qualify for food stamps. >> yes, and that's while working two jobs. >> reporter: west virginia teachers work an average of $45,000, well below the national average of $58,000. the striking teachers were offered a 2% pay increase, the first one in three years, followed by a 1% increase over the next two years. >> we're being pulled into the gutter, and our lives are about pulling people out of the gutter. >> listen, listen, listen. listen, listen, please. >> reporter: governor jim justice was jeered when he said the state can't afford anything more. >> then i can't help you. >> reporter: lindsay dolan, a mother of two, is concerned that low pay means that the best teachers go elsewhere. >> we need to have qualified teachers. they need to be well compensated, and they need to have the qualifications to teach our children. >> reporter: the teachers were warned the strike is illegal, jeff. they face anything from being

fined, being fired, to going to jail. >> glor: thank you very much. up next, monica lewinsky's changing view of her relationship with president clinton. not caused by a heart valve problem. but no matter where i ride, i go for my best. so if there's something better than warfarin, i'll go for that too. eliquis. eliquis reduced the risk of stroke better than warfarin, plus had less major bleeding than warfarin. eliquis had both. don't stop taking eliquis unless your doctor tells you to, as stopping increases your risk of having a stroke. eliquis can cause serious and in rare cases fatal bleeding. don't take eliquis if you have an artificial heart valve or abnormal bleeding. while taking eliquis, you may bruise more easily... and it may take longer than usual for any bleeding to stop. seek immediate medical care for sudden signs of bleeding, like unusual bruising. eliquis may increase your bleeding risk if you take certain medicines.
