>> reporter: witnesses telling officers they missed the suspect by five seconds, describing him as a thin black man about 6 feet tall. >> this has to stop. we will hunt this person down until we find him. >> reporter: police sate killing spree began on october 9th at 9:00 p.m. with the death of 22-year-old benjamin mitchell, shot while waiting alone at a bus stop. four days later -- >> she didn't have a chance to get married. >> reporter: the body of 32-year-old monica hoffa is found in this empty lot, down the street and around the corner from where mitchell was killed. moni monica's uncle, devastated. >> she loved everything. her interest was the community, the deaf community, she loved everybody. >> reporter: they're feeling it throughout the community. >> we don't want monica to be forgotten but we don't want everybody to forget there are two other families just as bad. >> reporter: following that death a third period, that of anthony maboa. >> it was really close. just five minutes later, the paramedics came.

>> reporter: he was a recent high school graduate who had autism. police say he was killed on his way home from work. >> i can't imagine what they're feeling right now. >> reporter: his family heartbroken. >> whoever did this, it's turned our life upside down. >> it is a shame that i won't be able to see him no more, talk to him no more. >> reporter: then this morning that fourth victim, ronald felton who was on his way to feed the homeless. >> i love him. he's still going to be with me. he'll be in my heart. >> reporter: police point to the fact that each victim was gunned down within a half mile of each other. they say in each shooting the victim was alone but wasn't robbed. >> keep, i keep urging and i keep stating the past days, please, whoever knows anything, stand up. do not be afraid. because this has to stop. it really does. >> we are in the hunting mode. >> reporter: police have been desperately searching for this person of interest. here he is walking in the direction of one of the crime scenes, then running away from

it. police have also released this longer enhanced video that they believe shows the same person strolling casually toward the crime scene earlier this night, flipping a cell phone in his hand. police hoping someone recognizes what they believe could be a significant clue. >> they take the phone, flip it. is that a habit? does someone know a fren, i see them do that all the time? so anything that may trip somebody's memory and help them recognize that person. that's what we're trying to bring their attention. >> reporter: neighbors have been concerned for weeks. can you talk about how strange this is for something like this to happen, how unnerving, how scary it is? >> this is the first time that anything this horrific has happened. >> reporter: ron davis says he won't be caught off guard. >> i just brought it out of the safe. i mean, now's the time. we got to protect my family. >> reporter: some parents saying are saying they now prefer to drive their children to school rather than having them walk alone. >> i have never seen this many police officers.

actually, it's unsettling, but it's settling. >> reporter: late last month i joined officer bob barrett as he conducted nightly patrols. >> hey, guys. are you heading home? >> reporter: checking on neighbors, especially those alone. and searching for the killer. we're passing right by the spot where benjamin mitchell was killed. >> that's why we're out here. we drive past that every day. it makes us remember why we're out here. we want this guy. we really do. so does the family. so does neighborhood. >> reporter: the sentiment too familiar to the residents of washington, d.c. area. >> we're interrupting your nightly news program. a frightening chain of events in montgomery county -- >> reporter: back in october of 2002, what was believed to be a lone sniper terrorized the d.c. beltway with a random shooting spree. in the end there would be ten murders over three weeks. >> people can't understand how someone can do this. >> there was just a seemingly random gunshot that came from seemingly anywhere -- >> reporter: in each shooting the victims were killed by a high-caliber rifle shot from a distance.

>> when i talk to people who were pumping their gas or going to the gym or eating at a diner, they walked crooked lines. they weave when they walk. they won't wear red or yellow outside anymore. >> everyone's keeping their children inside, no one's going to play grountds. all after-school activities canceled. you just want your children to be safe. >> reporter: the eighth victim was a 13-year-old child walking to school. >> someone is so mean-spirited -- that they shot a child. now all of our victims have been innocent, have been defenseless. >> reporter: the number of victims and fear on the rise caused then-president bush to step in. >> i've ordered the full resources of the federal government to help local law enforcement officials in their efforts to capture this person. >> reporter: more than then hundred federal officers were assigned to the case. abc contributor brad garrett, an fbi agent at the time, was one of them. >> literally this case had thousands and thousands of leads. people were scared. >> reporter: some of those leads began to pay off.

>> we got a vehicle description. then a tag number. that tag was spotted at a rest area in maryland not too far from d.c. by a guy going to work. he called it in. the police surrounded the car at some point. pulled them both out. placed them in the custody. interior 41-year-old john allen muhammad and 17-year-old lee boyd malvo were arrested and charged with the shootings. garrett interrogated malvo and got him to confess. >> i mentioned the movie the matrix. his eyes just dropped and immediately connected with mine. it got him to a point where he was willing at least to start talking to us. we got him to walk through a number of the shootings. is on to what occurred. was he driving? et cetera. we got a pretty decent confession out of him during those five six hours. >> reporter: 15 years later, brad garrett is hoping tampa police get a similar break in their case. >> the terror in the community obvious is going to be similar. and the utter importance it is

for the public to continue to feed the police with information to figure out who this guy is. that's ultimately what caught the d.c. snipers. >> reporter: back in florida tonight, police promising to keep their community safe. >> we need catch this killer before we have to notify one more family that one of their loved ones is dead. not in our town. not in this neighborhood. not now. and we're going to stay on this until we catch this guy. >> thy kingdom come, thy will be done -- >> reporter: for "nightline," i'm victor okendo in tampa, florida. next, we're with them in the aftermath of hurricanes irma and harvey. now we're revisiting families who lost everything. like for them now.for them now. i suad a lot on my mind. my 30-year marriage... ...my 3-month old business... plus...what if this happened again? i was given warfarin in the hospital, but wondered, was this the best treatment for me?

so i made a point to talk to my doctor. he told me about eliquis. eliquis treats dvt and pe blood clots and reduces the risk of them happening again. not only does eliquis treat dvt and pe blood clots. eliquis also had significantly less major bleeding than the standard treatment. eliquis had both... ...and that turned around my thinking. don't stop eliquis unless your doctor tells you to. eliquis can cause serious and in rare cases fatal bleeding. don't take eliquis if you have an artificial heart valve or abnormal bleeding. if you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. while taking eliquis, you may bruise more easily... and it may take longer than usual for 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. tell your doctor about all planned medical or dental procedures. eliquis treats dvt and pe blood clots. plus had less major bleeding. both made eliquis right for me. ask your doctor if switching to eliquis is right for you.

tonight we take an emotional journey back to the places hardest hit by this year's unrelenting storms. the magnitude of the aftermath so great that despite months of relief efforts, there's so much work to do. our team took to the seas and the skies. to reach families that lost everything. what they found was unparalleled spirit and resilience. here's abc's rob marciano. >> the house was pretty open. we were able to salvage the >> the house was pretty open. blinds, which was great. >> reporter: this is what it looks like to rebuild your life from scratch. >> i miss my house a lot. >> reporter: two months after hurricane harvey destroyed her neighborhood, the single mother of three is ready to bring her

family home. >> i think the most emotionally taxing thing for me is just how long this process is taking. >> reporter: we first met shazia when houston was a city in crisis. >> there they are! we're coming to get you! >> reporter: whole neighborhoods swallowed by the waters as more than 20 trillion gallons of rain poured down on texas and louisiana. in those first days, we embedded with a team of former military soldiers as they performed life-saving rescue operations. as the floodwaters receded, a harsh reality set in. more than 185,000 homes damaged or destroyed. shazia just one of many displaced. we made the journey back with her to survey the damage. nearly impossible to reach her neighborhood by foot. so a group of volunteers stepped in to help. >> this is the street where my kids play. they come off the bus at the entrance.

kids' bikes, our camping gear. >> reporter: inside, the weight of the damage began to sink in. >> my favorite furniture piece. i've had this almost 20 years. it's tough to see some of these things destroyed. >> reporter: now, months later, a second chance. >> every time i come here, i get a little emotional. because this is, you know, where my kids slept. so i'm looking forward to this room getting done. >> reporter: and the reality people here must face -- it's not if the next storm will hit, just when. >> there are concerns, too. what if this happens again? can we sustain something like this again? financially, emotionally. >> reporter: this texas suburb tells one part of a larger story. one of recovery and resilience. americans from the gulf coast down to puerto rico struggling to reset and rebuild in the wake of a season of massive storms. in the florida keys, piles of debris tell the story of hurricane irma.

130-mile-per-hour winds destroying nearly everything in its path. >> we don't have a roof on our house, we don't have anywhere to live, we're staying with friends. >> she's a special ed teacher at sugar loaf school. >> when we walked in there was water everywhere. >> what was going through your mind? could you even believe your eyes? >> no. this is our home. and it is hard to see somewhere where we raised our daughter -- >> reporter: while not destroyed, her home is badly damaged, filled with mold and unlivable. despite it all, teresa's fema claims were denied because of too little damage. >> my daughter wants to go home. she asks me every other day. mommy, when are we going home? >> reporter: this year's storm season costing upwards of $300 billion. all on top of the already spent $1.22 trillion caused by wither and climate disasters since the 1980s, a portion of which will now be on the taxpayers'

shoulders. in another corner of the united states, the idea of recovery is still distant on the horizon. the lingering devastation, an able reminder of how hurricane maria engulfed the tiny island of puerto rico. >> we are approaching where my grandmother was born and lived. >> reporter: my colleague sunny hostin traveled there. the enchanted island, as it's known. a place close to her heart. >> i was here last year. it's completely devastated. it doesn't look anything like it looked just last year around christmas time. >> reporter: for many there, like alta gracia gomez, there's just not enough help coming in from the outside. so all they can do is pick up the pieces that the hurricane left behind. >> she's saying, after the hurricane, there is no way she can live here. if you look, the roof is on the floor. at night, this is where she sleeps. they have a mosquito net over

their bed because everything is wet. fema sent her a letter which says they've reviewed everything and she's eligible for $500. she doesn't know what she would do with $500. >> reporter: 56 days later, still more than half the island is in the dark. residents are in desperate need of electricity. >> the truth is without power, the economy will not start rolling. without the economy not starting to roll, people cannot go back to work. students cannot go back to school. in more ways than one, it is all about power. >> reporter: and the farther you travel away from the capital san juan, the more precarious the situation gets. >> we're headed toward a town that had a bridge that connected two sides of the town. that bridge was decimated by the hurricane. literally half the bridge is gone. i've never seen anything like this before.

i mean, it's just -- we're talking about a concrete bridge. once you make your way across this riverbed and up the two-story ladder, you can see why the people in this town are calling themselves camp of the forgotten. >> i feel like i'm in jail. i haven't been able to get out. i'm afraid of the stairs. on the bridge. and i will not cross the river either. >> and it's been seven weeks. without electricity. you have some water now. >> yes. he gave us water. we had no water either. >> reporter: the weight of maria's fury not solely on puerto rico. >> both sides of the walls completely blown out. >> reporter: my colleague robin roberts traveled to the virgin islands, still reeling after a one-two punch of irma and then maria. >> wow. like "jurassic park."

>> after irma it looked like we got hit by a bomb. >> reporter: more than 70% here still living without power. >> so this is your home. >> this is it. >> but like so many here, he lost his home. reminded us of the beauty that still remains and the hope that was never forgotten. >> a lot of people here lost their home, lost their car, lost their job. but, you know, we got life. once you have life, you could build back, you could do whatever you need to do. >> reporter: you can't build black alone. >> how are you? oh, i've heard so much about you. >> reporter: mrs. phillips, a mother of 12, choosing to give back to others. she and her family began cooking meals for those in need. >> it's not too much extra. to share with the community. >> so it was out of necessity that you came up with this idea? >> yes. and because we were the only one in this neighborhood with a roof. >> reporter: the family cooks 250 meals per day, most of the food donated from others across the island.

>> no one would blame you if you said woe is me, life is terrible and just buried your head in the sand. but you didn't. >> because we raise our children to serve god and to always love your neighbor as yourself. >> reporter: for disparate parts of america bound through tragedy -- >> we're going to have a bigger puerto rico. a bigger and a better puerto rico. >> it's all about restoring hope and making sure people don't lose that hope. >> reporter: but now proving that the human spirit is stronger than any storm. >> i'm looking forward to starting fresh. i think all of us are looking forward to it. >> reporter: for "nightline," i'm rob marciano in the florida keys. next, meet the first ever hijab-earing barbie. inspired by u.s. olympic champions.
