>> were you just fearing the worst? >> absolutely. i thought i was going to die. >> reporter: georgie was on the flight. >> everybody was silent. it was just trashed all over. a lot of food thrown around. it was really wild. >> reporter: 172 passengers and 12 crew members were on board. lufthansa tells cbs news the flight experienced what's known as clear air turbulence, which can occur without visible weather phenomena or advanced warning. >> the fact that there was meal service going on, on this plane would indicate to me, at least, that there must not have been much of an advance warning. >> reporter: unexpected turbulence like that is precisely why it's so important to keep your seat bet on at all times, even when the sign is off. that passenger we talked to said the captain, upon landing, went to check on every passenger seat by seat, and that by the way, norah, included actor matthew mcconaughey and his wife, who were on that flight. >> wow, what a nightmare for those on board. thank you. tonight residents in east palestine, ohio, will finally

get their chance to confront representatives from the norfolk southern rail company at a town hall. meanwhile, the epa is ordering the rail company to expand its testing to include chemicals that stay in the environment longer. residents are still worried about their health one month after the accident. cbs's roxana saberi has new details. >> reporter: when the train derailed in east palestine, eric whiting filmed with his drone from home just a quarter of a mile away. now, nearly a month later, he still fears the contamination will harm his kids' health. but he doesn't have the means to move away. >> this is a chemical disaster in a town that you can't be near the water without getting sick. you're worried about having your kids play in your yard or your dog outside without getting sick. that's a shame that i have to worry about that in my own home. >> reporter: authorities say so far, tests show the town's air and municipal water are safe. but environmental activist erin

brockovich, who investigated contaminated water in california in the '90s, says residents have reason to be concerned. >> the narrative needs to be this community and what happened to them. they are not stupid. they are not making things up. >> reporter: so far, more than 2 million gallons of liquid wastewater and about 1,400 tons of solid waste have been hauled away to seven disposal sites in four states. just south of the disaster zone, in east liverpool, many say they don't want the toxic waste either. >> who knows what's going to come of this years down the road? i don't think we'll ever find out what the major effects are. >> what the health effects could be? >> absolutely, yeah. >> reporter: at the public meeting now happening in the school behind me, some residents hope to voice their concerns directly to norfolk southern representatives for the first time. norah, we've also learned the company's ceo plans to testify at a senate hearing a week from

today. >> we'll be watching. roxana saberi, thank you so much. well, we learned today that black face masks, a knife, and a gun were among the items seized by bliss when they searched the family home of university of idaho murder suspect bryan kohberger. kohberger was arrested at his parents home in december nearly seven weeks after four students were found stabbed to death. well, the newly unsealed search warrant documents show investigators also seized and dismantled kohberger's white hyundai elantra, the same type of car seen in surveillance footage near the murder scene. we want to turn now to the nation's growing opioid epidemic. there's been a surge of accidental overdose deaths in teens largely due to fentanyl. well, now 30 states are allowing the drug naloxone, which can reverse opioid overdoses, to be administered in schools. in tonight's "eye on america," cbs's christia ruffini takes us inside one district's effort to

save studstudents' lives. >> reporter: the most important lesson being taught at school today isn't for the students. it's for their teachers. >> how do you know when a person is overdosing? >> reporter: last month, a 14-year-old die afterward a suspected opioid overdose in an arlington, virginia, high school. the school district immediately took action with the rare step of requiring all secondary school teachers to learn how to use narcan or other generic forms of the drug naloxone. >> will that cause any problems if they're not overdosing on opioids? >> no, it will definitely not cause any problems. >> reporter: craig pepper says he and his fellow teachers want the lifesaving treatment on hand. >> so i'll have one in my desk, in my room, so i could administer it immediately if i had to. >> reporter: but teachers aren't the only ones getting an education. parents and community members are training sessions to learn how to use naloxone and bring it home. emily is the opioid's program manager for arlington county.

>> in a given month, we normally give out 150 to 200 boxes of narcan. we are probably getting close to 1,000 boxes requested in a two-week period. >> reporter: nationwide, fatal overdoses in young people jumped 123% from 2019 to 2021. the vast majority of those deaths involved fentanyl. >> who should be carrying narcan with them? >> everyone. it's a basic first aid tool that all of us should have in our medicine cabinets. >> reporter: according to the cdc, if an overdose is suspected, first call 911. then administer naloxone. >> it literally just goes in the nose and you just squirt it. >> reporter: keep the person awake and breathing until help arrives. >> let's say that you've given them a dose and you don't see any response. you can, after two minutes, you can give them another dose. >> reporter: ann has twin 14-year-old boys, the same age as the student who overdosed. >> it's scary to be a parent right now. if we can help anyone by being

trained, it's powerful. >> reporter: because when it comes to saving lives, knowledge is power. for "eye on america," christina ruffini, arlington, virginia. a towering inferno erupts in hong kong. the dramatic video from the scene. that's next. wondering what actually goes into your multivitamin? at new chapter, its' innovation, organic ingredients, and fermentation. fermentation? yes. formulated to help you body really truly absorb the natural goodness. new chapter. wellness, well done.

>> reporter: norah, good evening. the jury deliberated for only three hours. as alex murdaugh was handcuffed in the courtroom, he looked back at his surviving son, buster, who was there. he would not make eye contact with his father. >> verdict guilty. >> reporter: silently standing, alex murdaugh stared straight ahead as the jury read its verdict, finding him guilty of murdering his wife and son as well as two charges of possession of a weapon during the commission of a violent crime. >> the jury has been polled, and the verdict is a unanimous verdict. >> reporter: after nearly six weeks of testimony that captivated the world, it took the jury just three hours to convict murdaugh despite no eyewitnesses and investigators never finding a murder weapon or bloody clothes. earlier in the day, defense attorney jim griffin argued the police investigation was sloppy. >> how could he have butchered maggie and paul without leaving a trace of evidence within a matter of minutes? >> reporter: griffin also insisted murdaugh loved his family, and losing them was enough. >> on behalf of maggie and on

behalf of my friend paul, i respectfully request that you do not compound a family tragedy with another. >> reporter: but ultimately the jury disagreed, siding with the prosecution, who portrayed murdaugh as a serial liar, hiding his opioid addiction, his alleged financial crimes, and where he was minutes before the murders. >> today's verdict proves that no one, no one, no matter who you are in society, is above the law. >> reporter: judge clifton newman will sentence alex murdaugh right here tomorrow morning. he faces 30 years to life in prison without parole. norah. >> nikki battiste, who's been covering the trial for us. thank you. well, tonight tens of millions across the south from texas to mississippi are bracing for a likely outbreak of tornadoes, heavy rains, and flash flooding. meteorologist mike bettes from our partners at the weather channel is following the path of the storm for us. good evening, mike. >> norah, good evening.

we're in the midst of what is going to be a significant severe weather outbreak and three dangerous in particular we're following. tornadoes, a torcon of 5. places like dallas and little rock, you'll be affected. then there's that risk for high winds. 75-mile-per-hour winds or greater. those are hurricane-force winds. then two-inch diameter hail, could be the size of tennis balls or larger in isolated spots. hour by hour, let's walk you through that forecast. dallas gets hit this evening, working its way through the deep south, the mid-south as well. significant rain dumps out of this as well. so a large flood risk. tomorrow from montgomery and atlanta all the way to the ohio valley, we'll watch for significant storms here not to mention there is some cold air in place here. notice this, norah. from chicago to detroit to boston, watching for half a foot of snow or more. >> all right. on alert. thank you, mike. while the deadly snowstorm in california's sierra nevada has moved east, emergency crews are still trying to reach those trapped inside their homes. governor gavin newsom declared a state of emergency in more than

a dozen counties to help the relief effort. cbs's jonathan vigliotti is there. >> reporter: a desperate scene in the mountains of california. >> people are trapped in their homes and have been for now more than five days because the streets are not plowed. >> reporter: powerful images of the massive snowfall up to the rooftops. miles and miles of streets buried, impassable. this is the only route out for resident michelle calkins. this is her house. >> we need help. people are trapped in their homes. they cannot get medicine, heart medicine, insulin. >> reporter: plow operators are doing what they can. the state vowing to send emergency food and supplies. but here's what happened to one nearby market that had been open. >> our store was a total loss. the entire roof collapsed. there's nothing salvageable inside. >> reporter: to the south in malibu, the aftermath of the latest violent storm is still being felt. and in northern california, avalanche warnings remain in the sierra nevada.

one hit this apartment building near lake tahoe. all residents got out safely. to give you a sense of scale, this avalanche was a wall of ice and snow 25 feet tall, 200 yards wide, capable of moving at speeds up to 150 miles per hour. it uprooted entire trees, sending them like projectiles into this three-story apartment complex. it is the first avalanche to hit town since the mid-'90s, norah. >> stunning to see. jonathan vigliotti, thank you. back here in washington, it's rare for republicans and democrats to agree on anything, but today the house ethics committee voted unanimously to investigate embattled congressman george santos. we get more now from cbs's k caitlin huey-burns. >> reporter: the house ethics panel is looking at a wide range of potential violations, including whether congressman santos engaged in unlawful activity during his 2022 congressional campaign and failed to disclose required information on statements filed

with the house of representatives. new york democrat dan goldman filed one of those complaints. >> all of his lies about his background, his education, his employment history, his religion -- that doesn't violate any laws as it stands right now. so our ethics complaint really focused on the specific laws that we thought he may have violated. >> reporter: the panel is also looking at whether santos ated feral conflict of interest laws and engage poteia towards a volunteer staffer in his congressional office. the move by the ethics committee comes as cbs news exclusively learned that santos was questioned by the u.s. secret service in 2017 about an atm skimming operation and forced to hand over his cell phone. a santos associate, seen here, pleaded guilty to stealing atm numbers in seattle and sending them to brazil. santos was never charged, but in a court hearing, he's heard allegedly lying about his work history.

>> so what do you do for work? >> i'm an aspiring politician, and i work for goldman sachs. >> reporter: and, norah, for his part, santos said he will fully comply with this ethics committee investigation and will have no further comment at this time. but there's also federal and local investigations into his campaign finances at the same time. >> a lot of investigations. caitlin huey-burns, thank you so much. we're learning new details about what happened at that pennsylvania airport yesterday when a man allegedly tried to bring explosives onto an allegiant airlines flight. an fbi agent says marc muffley admits to stashing -- prosecutors say muffley called his girlfriend to pick him up when he heard his name over the loudspeaker. muffley also allegedly changed his phone number to avoid being tracked. well, he's now being held without bail. there's a lot more news ahead on the "cbs overnight news."

>> announcer: this is the "cbs overnight news." i'm jan crawford in washington. thanks for staying with us. this morning we have part two of our joint investigation with kaiser health news into a controversial dental device. it's called the anterior growth guidance appliance, or aga, supposedly capable of curing tmj and sleep apnea by remodeling the jaw. but some of the patients we spoke to insist it made their problems worse and even cost them their teeth. what's more, we found the device has not been reviewed by the food and drug administration. anna werner has the latest. >> reporter: nick hamilton, a

cybersecurity product manager, who says he's struged for decades with jaw problems and pain. >> my jaw itself would pop a lot. a lot of pain there, and my teeth didn't really line up. so like chewing food was very difficult. >> reporter: seeking solutions, in 2019, he found this facebook group run by an organization called the las vegas institute, or lvi, which calls itself a dental learning institution. in the group, people with similar problems discuss their treatment with a unique dental device called an anterior growth guidance appliance, or agga. it was invented by tennessee dentist dr. steve ga legal la, seen here in 2017. he's claimed the agga can cure problems like tmj and sleep apnea by expanding the jaw. >> can you cure tmj? yes. can you cure mild to moderate sleep apnea? yes. >> reporter: so hamilton selected a dentist from the list on lvi's website, one of many from around the country who have received agga training here at the las vegas institute.

>> he said this is absolutely a case i can fix. this will work for you. >> reporter: but after the installation of the agga device, which looks like a retainer with springs between forward and back teeth, hamilton says he felt intense pain and, over time, his front teeth flared out. >> they were very sensitive. biting into things was generally something i tried not to do because it felt unstable. >> reporter: so he says he raised his concerns in lvi's facebook group but -- >> i was removed from that group. >> so you got kicked out of the lvi group because you started asking questions about how this worked? >> yes. >> reporter: lvi's ceo said in court records he'd removed very fw people from the group, but some other patients we spoke to who were in the group also said airing problems wasn't tolerated. >> you would either get banned or you'd get a message from an administrator of the group telling you to, like, pipe down or don't ask questions, blah, blah, blah.

>> i mean i got banned from the lvi group. if you're not smart enough to understand it. >> it was like, oh, no, we're right, you know. we're right. there is no other -- there is no other way. >> reporter: hamilton finally decided he had to seek an outside opinion and got this warning. >> my orthodontist told me she was horrified. she said, i'm scared to death that you are going to lose up to eight teeth. >> up to eight teeth? >> mm-hmm. >> wow. >> reporter: cbs news and khn spoke to five patients who told us what they read in the lvi facebook group convinced them to get the agga. now they say they have health problems. both lvi and inventory d dr. galela are now facing lts suing dr. galela. in court, lvi said when used properly, the agga procedure can be an effective course of treatment in adult patients. but as to what studies back up the use of the device, lvi's

attorney told us, we're not aware of any peer-reviewed articles regarding agga working and agga not working. there's no literature to speak to it one way or another. attorney scott char ness represents clients suing over their agga treatment, including nick hamilton. >> and the science will show that it simply doesn't work. and i challenge them to show that it does. >> reporter: but we found the fda, which regulates dental devices, doesn't know whether it works either. in fact, we found they may not even have been aware it existed until we told them. >> i don't see how fda would know about this and let this out there. >> reporter: cara tennenbaum is a former policy adviser in the fda's device center. based on what you've seen about the agga, do you believe that the fda should be investigating this advice? >> i do, and my guess is the fda doesn't know about the device because no one is reporting the device to them. >> reporter: and she's right. cbs news and khn found no record of the agga being registered in

the database, which the fda later confirmed. something patients we spoke to didn't know until after they got it. >> i assumed that in order for a dentist to be selling it, it had to have backing that it was safe for use. >> like there was nothing for this. it was just basically, let's just toss this in people's mouths and see what it does. >> there needs to be regulation 100%. i would like to see this appliance to never be on anyone's mouth ever again. >> reporter: manufacturers are supposed to register devices with the fda, but in court, the agga's manufacturer said it has no record of communicating with the fda about the agga before making or selling it and said it falls into the least risky class of devices, similar to a dental retainer and is exempt from a pre-market review under an exemption for dental labs. inventory dr. galela said in a court deposition he believed the agga was outside the fda's

jurisdiction. lvi told us it's not subject to fda resignations. but tennenbaum disagrees. so you don't find this registered or listed with the fda, and should it be? >> absolutely. >> who's protecting the consumer if somebody puts a device out there and nobody looks at it and people are potentially harmed by it? >> that's the fda's job, and i think that there is a problem here because the fda is not aware of this device. >> when we spoke to lvi, its attorney says it no longer teaches classes on the device and disputed that it had ever directly taught dentists to use it. however, court documents show that agga classes were taught for years by lvi's own co-orthodontic directors. >> that was anna werner reporting. the fda wouldn't tell us i make. the overnight news is back in two minutes.

>> announcer: this is thbs overnight news." back here in washington, it's rare for republicans and democrats to agree on anything. but today the house ethics committee voted unanimously to investigate embattled congressman george santos. we get more now from cbs's caitlin huey-burns. >> reporter: the house ethics panel is looking at a wide range of potential violations, including whether congressman santos engaged in unlawful activity during his 2022 congressional campaign and failed to disclose required information on statements filed with the house of representatives. new york democrat dan goldman filed one of those complaints.

>> all of his lies about his background, his education, his employment history, his religion -- that doesn't violate any laws as it stands right now. so our ethics complaint really focused on the specific laws that we thought he may have violated. >> reporter: the panel is also looking at whether santos violated federal conflict of interest laws and engaged in potential sexual misconduct towards a volunteer staffer in his congressional office. the move by the ethics committee comes as cbs news exclusively learned that santos was questioned by the u.s. secret service in 2017 about an atm skimming operation and forced to hand over his cell phone. a santos associate, seen here, pleaded guilty to stealing atm numbers in seattle and sending them to brazil. santos was never charged, but in a court hearing, he's heard allegedly lying about his work history. >> so what do you do for work? >> i'm an aspiring politician,

and i work for goldman sachs. >> reporter: for his part, santos said he will fully comply with this ethics committee investigation and will have no further comment at this time. but there's also federal and local investigations into his campaign finances at the same time. >> a lot of investigations. caitlin huey-burns, thank you so much. well, tonight we're hearing from passengers who say they thought they were going to die after a flight from austin, texas, experienced severe turbulence, sending glass and food flying into the aisle. here's cbs's lilia luciano. >> reporter: it happened suddenly and without warning. lufthansa flight 469 flying from austin, texas, to frankfurt, germany, wednesday evening hit severe turbulence about 90 minutes after takeoff. >> lufthansa airbus a 330 experiencing severe turbulence. >> reporter: while cruising over tennessee, the plane shook violently and dropped 200 feet. as a precaution, pilots landed outside washington, d.c. at dulles international.

>> were you just fearing the worst? >> absolutely. i thought i was going to die. >> reporter: georgie was on the flight. >> everybody was silent. it was just trashed all over. a lot of food thrown around. it was really wild. >> reporter: 172 passengers and 12 crew members were on board. lufthansa tells cbs news the flight experienced what's known as clear air turbulence, which can occur without visible weather phenomena or advance warning. >> the fact that there was meal service going on, on this plane would indicate to me, at least, that there must not have been much of an advance warning. >> reporter: unexpected turbulence like that is precisely why it's so important to keep your seat belt on at all times, even when the sign is off. that passenger we talked to said the captain, upon landing, went to check on every passenger seat by seat, and that by the way, norah, included actor matthew mcconaughey and his wife, who were on that flight. >> wow, what a nightmare for those on board. thank you. tonight residents in east palestine, ohio, will finally

get their chance to confront representatives from the norfolk southern rail company at a town hall. meanwhile, the epa is ordering the rail company to expand its testing to include chemicals that stay in the environment longer. residents are still worried about their health one month after the accident. cbs's roxana saberi has new details. >> reporter: when the train derailed in east palestine, eric whiting filmed with his drone from home just a quarter of a mile away. now, nrl still fears the contamination will harm his kids' health. but he doesn't have the means to move away. >> this is a chemical disaster in a town that you can't be near the water without getting sick. you're worried about having your kids play in your yard or your dog go outside without getting sick. that's a shame that i have to worry about that in my own home. >> reporter: authorities say so far, tests show the town's air and municipal water are safe. >> how are you?

>> reporter: but environmental activist erin brockovich, who investigated contaminated water in california in the '90s, says residents have reason to be concerned. >> the narrative needs to be this community and what happened to them. they are not stupid. they are not making things up. >> reporter: so far, more than 2 million gallons of liquid wastewater and about 1,400 tons of solid waste have been hauled away to seven disposal sites in four just south of the disaster zone, in east liverpool, many say they don't want the toxic waste either. >> who knows what's going to come of this years down the road? i don't think we'll ever find out what the major effects are. >> what the health effects could be? >> absolutely, yeah. >> reporter: at the public meeting now happening in the school behind me, some residents hope to voice their concerns directly to norfolk southern representatives for the first time. norah, we've also learned the company's ceo plans to testify at a senate hearing a week from today. >> we'll be watching.

roxana saberi, thank you so much. well, we learned today that black face masks, a knife, and a gun were among the items seized by police when they searched the family of home university of idaho murder suspect bryan kohberger. kohberger was arrested at his parents' home in december nearly seven weeks after four students were found stabbed to death. well, the newly unsealed search warrant documents show investigators also seized and dismantled kohberger's white hyundai elantra, the same type of car seen in surveillance footage, near the murder scene. we want to turn now to the nation's growing opioid epidemic. there's been a surge of accidental overdose deaths in teens largely due to fentanyl. well, now 30 states are allowing the drug naloxone, which can reverse opioid overdoses, to be administered in schools. in tonight's "eye on america," cbs's christina ruffini takes us inside one district's effort to save students' lives.

>> reporter: the most important lesson being taught at school on this day isn't for the students. it's for their teachers. >> how do you know when a person is overdosing? >> reporter: last month, a 14-year-old died after a suspected opioid overdose in an arlington, virginia, high school. the school district immediately took action with the rare step of requiring all secondary schoolteachers to learn how to use narcan or other generic forms of the drug naloxone. which can reverse the effects of an overdose in just minutes. >> will that cause any problems if they're not overdosing on opioids? >> no, it will definitely not cause any problems. >> reporter: craig pepper says he and his fellow teachers want the lifesaving treatment on hand. >> so i'll have one in my desk, in my room, so i could administer it immediately if i had to. >> reporter: but teachers aren't the only ones getting an education. parents and community members are rushing to these free training sessions to learn how to use naloxone and bring it home. emily siqveland is the opioid program manager for arlington county.

>> in a given month, we normally give out 150 to 200 boxes of narcan. we are probably getting close to 1,000 boxes requested in a two-week period. >> reporter: nationwide, fatal overdoses in young people jumped 123% from 2019 to 2021. the vast majority of those deaths involved fentanyl. >> who should be carrying narcan with them? >> everyone. it's a basic first aid tool that all of us should have in our medicine cabinets. >> reporter: according to the cdc, if an overdose is suspected, first call 911. then administer naloxone. >> it literally just goes in the nose and you just squirt it. >> reporter: keep the person awake and breathing until help arrives. >> let's say that you've given them a dose and you don't see any response. you can -- after two minutes, you can give them another dose. >> reporter: ann seitz has twin 14-year-old boys, the same age as the student who overdosed. >> it's scary to be a parent right now. if we can help anyone by being trained, it's powerful.

>> reporter: because when it comes to saving lives, knowledge is power. for "eye on america," christina ruffini, arlington, virginia. a towering inferno erupts in hong kong. the dramatic video from the scene. that's next. who says you have to spend more on skincare to get results? i power up my skin with olay. it works. guaranteed. try niacinamide for strength, retinol 24 for smoothness and vitamin c for brightness. i like to use them all! olay. face anything.
