good evening. thanks for joining us. we begin tonightmicl rcu of soa notre dame's sacred treasures.

and stunning new images of the epic battle to save the beloved cathedral. james longman takes us into the blazing inferno. >> reporter: notre dame now sits as an open wound. tonight new images take us inside the 12-hour battle to save the cathedral. rushing into the danger. firefighters shooting powerful jets of water into the 850 year old cathedral. a legion descending on the scene, a major command post outside. as this piece of french history burned, the fire department sending up drones for a bird's-eye view. what they saw, the entire roof engulfed. this is what it looked like before. it's nicknamed the forest, built in the 13th century out of 13,000 trees, now

gasps as the famous spire fell. firefighters using water from the river. their hoses trained on the church as day became night. scaling the scaffolding, the famous gargoyles overhead. then a robot sent into the cathedral as embers rained on the altar. firefighters staring at the smoldering wreckage. this morning by daylight, a wider view of the destruction inside. can you see firemen are still working to assess the damage. working out fif the building is still safe. but all around us, black ash, a memory of what happened last night. >> part of the roof has disappeared. and some water leakages downstairs. and just a nightmare. >> reporter: the timeline of the disaster coming into focus. a fire alarm sounding at 6:20 p.m. inspectors search the building but find nothing.

23 minutes later another alarm. that time they see the flames, but it's too late. that 23-minute gap now part of an investigation authorities say will be long and complex. the cathedral home to a vast collection of christian treasures. from the immaculate rose windows and the iconic pipe organ to the famed crown of thorns seen in national geographic's "the story of god" with morgan freeman. >> more than 13 million people come here every year, but only a fraction know that these vaulted ceilings house one of the most precious and closely-guarded relics in all krichristendom. >> reporter: the crown christians believe jesus christ

himself wore on the cross. >> i know you said that if there is a crown of thorns, this is it. >> yes. >> but what if there's not? >> well, if it really touched christ, of course, it is obvious. but even if it's not the true one, it's worth remembering, okay, he really was on earth. he was a truman. it could bear that. it could have that on his very head. and this is no story. this is no tale or symbol or obstruction, this is history, this is concrete. >> reporter: that piece of history along with many others rescued from the flames and taken to the louvre for safekeeping. how much of the artifacts have been saved? >> something like 80%. >> reporter: 80% of the artifacts have been snaaved. >> yes. >> reporter: that's astounding.

they are investigating whether the flames are linked to construction work ongoing. today macron vowed to rebuild in five years. donations are flowing in much of it from wealthy citizens. >> it gives me hope that we're going to be able to rebuild in full shape. i think that the reconstruction will be a sign of these believers in jesus christ. >> reporter: some believe it could take much longer. a precise digital replica of the cathedral captured in 2015 has bolstered hopes for the reconstruction. >> there's nothing written about it. there's nothing written that they said i built my cathedral because. so i've been using more sophisticated technology these

days to get more answers from the buildings. >> reporter: the architectural historian mapped it using kugts edge technology. his work will likely prove crucial to any rebuilding efforts. >> his major mission was to make sure as many people as possible understood the beauty of these gothic structures. >> reporter: lindsey cook of vassar college inherited the project after his death. >> it took place over many years. this is something much more crucial especially after the fire at notre dame. it's happened to so many gothic churches. it's not at all t projecter: windsor castle was saw the official residence reopened five years later. fire gutted this cathedral in 2009. but it was restored for more than $30 million in 2014. and just last year, a fire

consumed the national museum of brazil, decimating 90% of its collection. for the people of france, the return of their beloved cathedral cannot come soon enough. >> it was like getting a call from the hospital and you weren't sure threy were going t make it and you had to get down there and say bye. >> reporter: she was one of the hundreds who flocked to the site watching as the flames spread across the roof. >> it was like watching a really surreal, horrible movie, and everyone went ah! >> reporter: you saw the glass explode. >> saw the glass explode. it was, there were so many people, but it was so quiet. so, so quiet. >> reporter: and people here were moved. they were crying? >> yeah, there were people sobbing. there was a woman behind me sobbing into her phone. it was just shock. >> reporter: people have been coming down here all day, and yes, there are a lot of

foreigners, but mostly, it's parisians looking down to see what happened to their favorite building. for "nightline," james longman in paris. >> our thanks to james and our team in paris. up next, the new warning before you climb in the back seat of a ride share. the manhunt for the suspect posing as a driver, turning on his passenger in an elevator. the startling surveillance. people with type 2 diabetes ncer) are excited about the potential of once-weekly ozempic®. in a study with ozempic®, a majority of adults loweand a1cr blood sugar of less than seven and maintained it. oh! under seven? and you may lose weight. in the same one-year study, adults lost on average up to 12 pounds. oh! up to 12 pounds? a two-year study showed that ozempic® does not increase the risk of major cardiovascular events like heart attack, stroke, or death. oh! no increased risk? ♪ oh, oh, oh, ozempic®! ♪ ozempic® should not be the first medicine for treating diabetes,

elevator where he tries to take her purse, before entering her apartment, stealing property and fleeing. this happening one day before the death of samantha josephson who was kidnapped and murdered by a man she thought was her uber driver. >> i don't think it was even in our sight that this was an issue, until unfortunately this happened. it could happen to anyone. >> reporter: samantha was a force. a 21 year old with the world at her finger tips. a senior at the university south carolina. her parents, seymour and marcy say she dreamt of becoming a lawyer. >> fabulous. kind, funny, very, very funny. a best friend to everyone. good sister to sydney. >> always smiling. >> always smiling. >> reporter: you smile when you say that. >> i do. >> she wanted to make a difference. she was actually interested in international law. >> reporter: just two weeks after their daughter's murder, the josephsons say they feel compelled to speak out, calling for federal regulation on the

ride sharing industry and urging companies like you knuber and l enhance safety protocols. >> we don't want anything like this to happen to any other parent again. so we felt, do this now. >> reporter: it was a typical night and samantha was out with friends at a bar near usc's campus. >> she was so excited because she hadn't been out with her friends for a couple weekends. >> reporter: she ordered a uber. >> she was being responsible going home because she had to work in the morning. >> reporter: she can be seen walking alone outside in this surveillance footage. black chevy impala pulled up and she got in. >> she mistakenly got in thinking it was a uber ride. >> reporter: it was not. the next day, her friends, concerned they hadn't heard from her called her parents. >> samantha's boyfriend called me and said i just want to let you know that samantha didn't come home last night, and they called the police, and i just

kind of froze, and called seymour. >> we were still talking to the police as we were in the car to drive, to drive down. when we got there, about 12:00, 12:15, they brought us into a conference room. at that point it confirmed. told us. so that was a hard moment. >> reporter: police told them the unthinkable. their daughter was dead. her body had been found by hunters in a wooded area in the rural part of the county. devastated, marcy and seymour had to deliver the news to their youngest daughter sydney. >> making that phone call back to her was probably one of the hardest days of my life. >> reporter: may i ask what you said to her? >> that she's no longer here. she's dead. it's still, obviously hurts.

we're still very emotional. >> reporter: police tracked down the vehicle from that surveillance video and arrested 25-year-old nathaniel roland at a traffic stop around 3:00 a.m. inside they found liquid bleach, cleaning wipes and window cleaner. >> the chevy impala had a large amount of liquid that we believed to be blood, and once they did a presumptive test, it, in fact, was confirmed to be blood. >> reporter: police say the suspect trapped samantha in his car. >> the child safety locks were activated on the door that would not allow someone to, the means of escape from the back of the suspect vehicle. >> reporter: roland has been charged with kidnapping and murder. his parents spoke to a fox affiliate, denying their son's involvement. about. sorry it happened, but ie >> reporte ia court hearing,der

not attend, josephson's mother delivered this emotional plea. >> he should never be allowed to walk free again for what he did to my daughter or given the opportunity to hurt anyone else. samantha josephson. my daughter's name is samantha josephson. don't ever forget the name samantha josephson. shame on him. >> reporter: you said her name and made the statement more about her and less about him. >> it's the way it should be. >> it's really about my daughter and making it that nobody else is going to go through what we're going through. >> reporter: while the family does not blame uber for samantha's death, they think uber and other ride share companies could do more to keep passengers safe. >> i think all the ride sharing companies out there need to do more. they need to look at the safety and how they can enhance the industry. >> reporter: just yesterday the ride share company lyft announced that they're adding two new safety features in the

wake of samantha's death. continuous criminal background checks and an enhanced identity verification process. but they think they should consider developing bar code technology to match drivers with passengers. >> you have to have a smartphone. can you put a qr code, a bar code, put it on the door. if that's your ride, it turns green. >> reporter: in a statement to abc news, a spokesperson for uber said, our hearts remain with the josephson family. we're always looking to build on our core safety feature, such as the license plate, car make and model and driver photo shown notice a in the app prior to the trip. they want all ride share cars to have a front and back license plate. >> there are 19 states that do not have a front license plate. and south carolina happened to be one of them. so we're saying to make that mandated. we have our children. they grow up.

and we teach them, don't talk to strangers, don't get into a car with a stranger. and what do we do now with a ride share? they get in a car with a stranger. >> reporter: recently south carolina's house of representatives passed a bill named a named after samantha. >> the bill mandates that any driver, when there's a driver working on duty, there would have to be an illuminated light. >> individuals need to be accountable. and they have to look at the license plate. they have to look at the driver. >> reporter: the family has turned their pain into action. launching a foundation called what's my name. asking passengers to ask before they step into the car. >> sammy would have wanted us to do this. >> because it was her goal to help change the world. yes. >> reporter: samantha was planning to head to law school in the fall on a full scholarship. she was set to finish up school and graduate next month. >> may 11 is her graduation. >> reporter: what will you all

do that day? >> we're going to go to it. i think it's going to be a really diff really difficult day, but we need to go to it for ourselves. >> they're go being to do a moment of silence for her, and i really wanted to be there for her. >> our thanks to byron for that report. and next, three months, t strangers, one emotional meeting. the teenager getting the life-saving gift that keeps on giving. unpredictable crohn's symptoms following you? for adults with moderately to severely active crohn's disease, stelara® works differently. studies showed relief and remission, with dosing every 8 weeks. stelara® may lower your ability to fight infections and may increase your risk of infections and cancer. some serious infections require hospitalization.ions before treatment, get tested for tb. tell your doctor if you have an infection or flu-like symptoms or sores, have had cancer, or develop new skin growths, or if anyone in your house needs or recently had a vaccine. alert your doctor of new or worsening problems,
