hashtag "we stand with wdbj." es have a series of reports tonight. first justice correspondent jeff pegues. in moneta virginia with the latest in the investigation. >> reporter: police searched vester flanagan's car, apartment, and a nearby dumpster looking for clues to explain why he opened fire on his former coworkers on live television, and then posted his own video online. his image was caught on adam adam ward's falling camera, and after the shooting, court papers say flanagan sent a text message to a friend making a reference to having done something stupid. inside flanagan's getaway vehicle police found a glock pistol and ammunition along with a briefcase with three license plates, a wig, and a black hat. also inside, a to-do list, the contents of which was not released. officials say that flanagan gun shop lesht two glock pistols from this gun shop less than 10 minutes away from wdbj.

>> at a trailer park on -- >> reporter: flanagan, who used the name bryce williams on air, was fired from the station in 2013. he sued for discrimination and wrongful termination. in court papers, the station said that flanagan was dismissed for unsatisfactory job performance, and that after being let go, he said, "you better call police because i'm going to make a big stink." flanagan's case was dismissed. station general manager jeff marks said flanagan was initially ordered to get counseling. >> we made it mandatory that he seek help from our employee assistance program. we complied with what we asked him to do. >> the loss of a job can be a precipitator. >> reporter: mary ellen o'toole, a former criminal profiler with the f.b.i., says the evidence suggests flanagan's killing spree may not have been over. >> so when the police have recovered to-do lists or notes or journals in his car, writings, i think that becomes

significant because hopefully he put in there where he intended to go. >> reporter: flanagan, a california native, stayed in this area even after he was fired. the other reporters in town would see him. maurice, station management says it did not know that he was such a threat until alison parker and adam ward were gunned down right here on this deck overlooking a lake. >> dubois: jeff pegues, thank you tonight. now, to the tributes being paid to the victims. kris van cleave has that part of the story. >> it was yesterday around this time that we went live to alison parker and photojournalist adam ward. they were out in the field. the story was like so many others that they did all the time. >> reporter: a moment of silence marking the void left by two young lives taken. anchor kimberly mcbroom was on the air when parker and ward were murdered. how powerful was that moment of silence? >> it was powerful to me. we've relied on each other, all of us have. we've held hands. we've hugged. i mean, we're family.

we are a family. >> reporter: the tragedy has moved many to pay their respects at a growing memorial in front of the station. adam ward's fiancé, melissa ott, posted a touching tribute on facebook. >> your life changes. but in their memory, you want it to change in a way that something positive comes out of it, and that's all you can hope for. >> reporter: parker's parents, barbara and andy, say they will now advocate for stronger gun laws. >> i'm going to do whatever it takes and i'm going to be relentless about it. i'm not going to stop until we get change. >> reporter: vicki gardiner survived the shooting and today was upgraded to good condition. tim, her husband of 40 years, thought he had lost her until she called from the ambulance. >> she told me she had been shot in the back and she didn't know why she was still alive. epe guy fired several times. >> reporter: staff here at the

station are wearing these ribbons to honor adam and alison. maurice, several vigils are happening around town tonight. >> dubois: kris, thank you. some public health officials say gun violence, just like car accidents and smoking-related illnesses can be prevented or at least reduced. we'll have both sides of that issue later on in the broadcast. vice president joe biden said he will decide by the end of the summer whether he will run for the democratic presidential nomination. but he has one major concern. here's julianna goldman. >> reporter: in a conference call with party leaders, biden said the death of his eldest son, beau, has left him torn. in audio obtained by cnn, he said he doesn't know if he or his family has the emotional fuel to endure a campaign. >> i cannot even imagine the grief and the heartbreak.

>> reporter: democratic front- runner hillary clinton was sympathetic, but she also indicated she would not cede any ground to the vice president. >> he has to do what he has to do, but i'm just going to continue with my campaign. >> reporter: democratic national committee member alma gonzalez was on the call with biden. >> i think that until you make a commitment, until everyone has had a chance to put their hat in the ring and be vetted, we have to be open minded. >> reporter: a new national poll shows biden has a bigger lead against the republican front- runner, donald trump, than clinton, and the vice president is viewed far more favorably than clinton among voters in both parties. it's another sign that the fallout from clinton's private e-mail server continues to dog her campaign, and facing criticisms from democrats, she's striking a more contrite tone. >> it clearly wasn't the best choice. i should have used two e-mails, one personal, one for work. and i take responsibility for that decision.

>> reporter: d.n.c. members at their summer meeting here in minneapolis will hear from hillary clinton tomorrow and other democratic presidential candidates tomorrow. joe biden won't be here, but, maurice, earlier today he met with the head of the a.f.l.- c.i.o. union-- a key democratic ally. >> dubois: thank you, julianna. hillary clinton is going after her republican opponents on the issue of funding for women's health. in cleveland today, she appeared to compare them to terrorists. >> i would like these republican candidates to look the mom in the eye who caught her breast cancer early because she was able to get a screening for cancer. ( applause ) or anyone who's ever been protected by an h.i.v. test. now, extreme views about women, we expect that from some of the terrorist groups. t waxpect that from people who don't want to live in the modern world.

but it's a little hard to take coming from republicans who want to be the president of the united states. >> dubois: republican candidates were quick to respond, including jeb bush, who tweeted this saying this: contending for quote of the day is this today from donald trump. "it's my hair, i swear." at a campaign appearance in south carolina, trump insisted his hair was real and challenged a young lady to see for herself. her verdict, "i believe it is." to the economy now. it is also growing for real at 3.7% in the second quarter, six times faster than the first quarter. that news today gave wall street a boost. the dow soared 369 points, it's second straight triple-digits

gain. tropical storm erika is bearing down on puerto rico and the virgin islands tonight after pounding the caribbean island of dominica. 15 inches of rain unleashed floods and mudslides there that killed at least four people. another 20 are missing. so is erika headed for the u.s. mainland? eric fisher is chief meteorologist at our cbs station in boston, wbz. eric? >> maurice, good evening. erika is a disorganized tropical storm but it doesn't take a lot when you have the tropical rain to cause a lot of issues. as you saw in the leeward islands earlier today, tropical storm warnings continued there. puerto rico, the northern shores of the dominican republic, and tropical storm watches now out for the turks and caicos. this is the track as we head through the next few days. high certainty here, it should cross puerto rico tonight, remain a tropical storm as it moves off to the north and west. it's when it arrives in the bahamas this weekend that we start to see some uncertainty in the track. that's why you see the track cone expanding at this point. we head towards the beginning of the week it's expected to be a category 1 hurricane at least

off the shore of florida and then drift its way northward as we head into the week. once it gets to the bahamas it encounters very warm waters. that is fuel for tropical systems and wind shear will die down. that's a chance for this storm to intensify. the steering currents parallel the coast, so maurice, this is a storm that should be along the southeast coast for several days next week, a story that's going to stick around for many days. >> dubois: and we'll be watching. eric fisher in boston tonight, thank you. president obama walked the streets of new orleans today and praised the city's rebuilding efforts 10 years after hurricane katrina killed more than 1,000 people and left much of it underwater. omar villafranca is there tonight. omar. >> reporter: the president just wrapped up his speech in front of an enthusiastic crowd here at this community center. this is the ninth time the president has visited new orleans since he took office. ( cheers ) earlier, the president, along

with new orleans mayor mitch landrieu -- i'm sorry, the new toured the streets of treme, one of the oldest black neighborhoods in the country devastated by the storm. relaxed and smiling he was welcomed like a long-lost relative. he went door to door shaking hands, hugging babies and chatting with residents, many now living in rebuilt homes. at his speech in the lower ninth ward, president obama paid tribute to the people of new orleans. >> i'm here to hold up a mirror and say because of you, the people of new orleans, working together, this city is moving in the right direction, and i have never been more confident that together we will get to where we need to go. >> reporter: the president said katrina is an example of what happened when the government fails. maurice, he also added that the recovery is an example of what happens when local, state, and federal agencies work together. >> dubois: omar, thank you very much. new orleans lost more than half its population after katrina. for many, there was no place to live. 134,000 homes were damaged or destroyed, but since then, 81% have been rebuilt, thanks to an army of builders.

michelle miller has more on that. >> reporter: dozens of volunteers are putting the finishing touches on the home of francita clemons. she and her mother abandoned it just before the deluge. >> i left the day before the storm to a finished house. now i have a finished house again. >> reporter: this moment is bittersweet. her mother died long before she got help to rebuild. is it hard to ask for help? >> yes. >> reporter: why? >> your pride. >> hello, young people. >> reporter: but last year, she found out about the st. bernard project, a nonprofit started by zack rosenburg and his wife, liz mccartney. the couple came from washington, d.c. to volunteer two months after the storm. they planned to stay for two weeks. they never left. >> what we first saw was wholly inconsistent with the america we knew. it was either a step forward or a step backwards and our first step was forward. >> reporter: so far, the group has rebuilt 614 homes, more than

any other nonprofit in the new orleans area. >> we just started a three-year, $10 million campaign to rebuild 240 houses. >> reporter: but there's a lot of work to do. more than 5,000 families are still waiting for their homes to be rebuilt. requests to the st. bernard project are up 25% this year. >> we have tons of volunteers that want to come and help. the only thing that we're missing is more funding. >> boy, so many things i went through in life. >> reporter: 94-year-old lee edward is a world war ii vet who built this home with his own hands. >> home means 100% of my life. >> reporter: katrina's winds blew part of his roof off and cracked his foundation. he patched up what he could with fema money but ran out before the job was done. he's one of more than 100 people still on the project's waiting list. you never thought of moving out of this house? >> no. i'm going to die here. >> reporter: and, maurice, on this street in the ninth ward of new orleans, you can still see the challenges facing this city.

one home rebuilt next door to an abandoned and blighted property. >> dubois: michelle miller, thank you. the world's fastest man is taken down on the track. and a ballet star has a message for these students when the cbs evening news continues.

es dubois: the united states has about 4% of the world's population, but nearly half the civilian-owned guns. with gun violence on the rise, some public health officials say it's time to change our approach to the problem. here's jeff glor. >> reporter: it is not the first time we've seen a horrific shooting. it is not the first time it's been recorded. but for many, this is a first-- thinking about gun violence, the same way we think about car accidents or smoking, as a public health issue. >> the real tragedy here is that a lot of it is preventable. >> reporter: georges benjamin is the executive director of the american public health association. >> seat belts, airbags, and all

those things we didn't have before have dramatically reduced the number of automobile crashes and the human toll from that. we can do the same thing with firearms. >> reporter: the web site shootingtracker.com estimates once a day in this country four or more people have been shot in a mass shooting so far this year. according to the c.d.c., more than 90 people are killed by a firearm every day. 90 people every day, is that getting worse? >> it's getting worse. look at what's happening in our big cities. a lot of it is gang related, but it's not always gang related. >> reporter: benjamin says a public health campaign that focuses on securing guns in the home increased firearm safety training, and more screening of the mentally ill focuses less on gun control politics and more on prevention. >> you can do it in a non- threatening manner and the non- threatening aspect is what we really need to move this issue forward. >> reporter: the notion that gun violence should be treated as a public health issue, do you buy

that? >> no, not really. >> reporter: john lott is president of the crime prevention research center and author of the book "more guns, less crime." how does more guns mean less crimes? wo every country in the world or place in the world that's banned guns has seen an increase in murder rates. it's not just washington, d.c. and chicago. >> reporter: to those who say this is just another attempt to restrict gun ownership and seize firearms how do you respond? >> the second amendment is real, we respect it, but let's figure out how to save lives together. >> reporter: gun use in suicides is even worse. the c.d.c. says for every homicide in this country, two people take their own lives with a gun. maurice. >> dubois: jeff glor, thank you. in just a moment, darrell dawkins, fans loved him. backboards, not so much. not so much. m new ensure activeh protein. i help you recharge with nutritious energy and strength to keep you active. come on pear, it's only a half gallon.

the teacher who discovered him as a dancer moments after he flunked an acting audition. >> and i left out, and i saw those girls stretching before their ballet audition, and i thought, "oh, my sister does splits at home. i think i can do one. i'll try that." >> i saw a darling little boy who really wanted to work. >> reporter: what did that mean to you? >> everything, everything. i think when someone-- when you can-- when you feel someone invest in you like that it's beautiful. try to round your elbow a bit more. yeah. >> reporter: he returned that investment with a message for the students. to ignore anyone who says black dancers can't succeed in ballet. >> there's no reason you couldn't be there either. it's not like, you know, i'm not a super hero. i'm just like you. >> reporter: the dancers told him what they face is high school peer pressure not to try so hard. >> and when you're different, you're the boy who dances, it's a lot of fear that comes along with that.

>> reporter: but the way to handle the doubters, he told them-- >> "eric, why you can't dance?" >> reporter: is to turn everything they say into resolve. >> i just thought of it as, like, okay, i need to work harder. >> reporter: to students like sophomore kiya snow his advice was a shot of courage. >> if you want to be a dancer, be a dancer. don't listen to the negative comments. >> you're still thinking about everything. >> reporter: and by the end of this visit from the boy who dances, the class had learned more than his approach to technique. >> cheese! >> reporter: what they'd learned was his approach to life. >> nice to meet you. >> reporter: wyatt andrews, cbs news, suitland, maryland. >> dubois: and that is the cbs evening news for tonight. for scott pelley, i'm maurice dubois. thank you for joining us. see you again tomorrow. have a good night. captioning sponsored by cbs captioned by media access group at wgbh access.wgbh.org
