their hands up in st. louis. police now say the 19-year-old, who graduated last year, had more than 600 rounds of ammunition. and tonight, the handwritten note he left behind. we are not going to report on its entirety, but the sheriff tonight on the line that was not only disturbing, but a wakeup call yet again. abc's alex perez leading us off in st. louis. >> it's the police! >> reporter: the chilling images playing out inside a st. louis classroom. terrified students running for their lives. and tonight, authorities have revealed the gunman was another young person. and they say this was the ar-15-style weapon he used to kill a teacher and a tenth grader. >> he came into the building with more than 600 rounds of ammunition on his person. >> reporter: the police chief today reading excerpts from a disturbing handwritten note 19-year-old orlando harris -- who graduated from the school last year -- left behind in his vehicle. >> "i've been an isolated loner my entire life. this was the perfect storm for a mass shooter." >> reporter: the 19-year-old fatally wounded in a shootout with police.

he had already killed sophomore and varsity dance team member alexandria bell. her family, heartbroken. >> what made her amazing was no matter how mad, how frustrated you were, she'd always make that that frown turn into a smile. she could always brighten up your day. >> reporter: the gunman also killing 61-year-old health teacher jean kuczka. the cross country coach was a mother of five, and grandmother to seven. >> she put herself between them and harm, between them and danger. she was love. she was the embodiment of love. >> reporter: seven other students injured. four grazed by bullets. one with a broken ankle after jumping from the building to safety. and david, authorities say they won't reveal how exactly the shooter entered the building for security reasons, but they do say it was not through an official entry point.

authorities are now also working to determine if the person who sold the gunman that rifle could face criminal charges. david? >> all right, alex perez leading us off tonight. alex, thank you. we continue to monitor those reports late today of the largest earthquake to hit the san francisco bay area in nearly a decade. a 5.1 earthquake centered just outside san jose. residents are being warned tonight to stay alert. scientists always say be prepared for what could come after. and at this hour, there are already reports of aftershocks. abc's elwyn lopez in california tonight. >> reporter: tonight, a powerful 5.1 magnitude earthquake hitting california's bay area. >> all units and stations on cal fire -- a 5.1 seismic event has just occurred near the community of san jose. report any serious injuries or major damage immediately. >> reporter: the quake, striking about 12 miles east of san jose. this man feeling the tremor, running into his home for a child, waiting it out under the doorway. >> get under the doorway! >> reporter: the earthquake

swinging this chandelier. and you can hear the glasses rattling in this apartment. trains suspended, but officials tonight saying it caused minimal damage. still, a stark reminder of the ever-present threat. today's earthquake is just the fourth in the past 30 years to top a magnitude five in the bay area. >> you should expect more aftershocks. about half of our big earthquakes are preceded by some sort of foreshock, and it's a 5% chance of something larger going forward. >> reporter: and david, here in california, the last major earthquake was a 7.1 in 2019, and david, a panel of experts estimates that the bay area could see a 6.7 magnitude earthquake or above in the next 30 years. and here we have a statewide app that can warn residents about those earthquakes in just seconds. david? >> yeah, at least the technology has gotten better on that front. elwyn lopez tonight. elwyn, thank you. now to the growing concern over what doctors are seeing in hospitals across this country. the triple threat tonight of covid, flu, and that virus rsv,

all hitting at once. take a look at the map tonight. 14 states and washington, d.c. all in red there, really across the country, north, south, right through the middle of the country. these are all states with hospitals with pediatric beds at more than 80% capacity already. tonight here, dr. jha on what parents should know. steve osunsami from atlanta now. >> reporter: what they're seeing at children's hospitals across atlanta tonight, they're seeing in places across the country -- about three times more sick children than usual. in one location, they had to put up a tent back in august to help process all the extra children. this time it's not just covid, it's the flu and a seasonal virus that mostly affects children called rsv. this evening, 5-month-old bentley phillips is hospitalized with rsv in green bay, wisconsin. >> it started with the wheezing. he progressed so fast. his oxygen was so low, we don't know what would have happened if we were at home any longer than we were. >> reporter: it's early in the

winter cold season, and children sick with respiratory illnesses are filling up pediatric beds across the country. in 14 states and in washington, d.c., they're already more than 80% full. in severe cases, the children can't breathe. >> really small babies have a harder time in clearing their own congestion. they can't sneeze. they can't cough as hard. they don't have the chest muscles to really expel all that. this is why young kids are at increased risk when it comes to rsv, influenza, of getting hospitalized. >> reporter: our mary bruce, at the white today, was pressing officials. >> how concerned are you that this limited capacity will be stretched even more? and what can you say to parents who are concerned that they may have trouble finding care if their child has rsv or the flu or covid? >> first thing that i would recommend to parents, which is what i've done as a parent, is gotten my kids vaccinated. because if you can get them vaccinated against flu and covid, that takes two of the three issues off the table. it also creates more capacity in the health care system and it just makes it better for everybody. >> reporter: authorities are warning about a possible triple-demic, of covid, the flu, and rsv. >> we're really tracking health

care capacity very, very closely across pediatric hospitals. and obviously, if hospitals need help, we will step in and help them to make sure that all kids across america get the care they need. >> reporter: at children's health care of atlanta, they're telling parents it's still not too late to get their kids vaccinated. and they want parents to know that 95% of children hospitalized here tonight were not vaccinated for the flu and/or had incomplete vaccines for covid. what you're seeing is that most of the kids who are coming in are unvaccinated for covid and flu. >> those that are requiring hospitalization or have severe infections, yes. >> reporter: there is no available vaccine for rsv, but there is for covid and the flu. doctors at this hospital behind me say that 75% of the children hospitalized here this evening with respiratory illnesses are sick with the flu and almost all of them weren't vaccinated. david? >> all right, steve osunsami tonight. steve, thank you. we turn to russia tonight

and wnba star brittney griner in court today, her appeal rejected. her plea from behind bars. tonight, the u.s. responding. and here's our chief global affairs correspondent martha raddatz. >> reporter: wnba star brittney griner's appeal denied. appearing in court via a video link, apologizing to the russians and appealing to the court for a lighter sentence. >> i've been here almost eight months, and people with more severe crimes have gotten less than what i was given. >> reporter: griner now waiting to serve out what remains of her nine-year sentence, charged with carrying vape cartridges with cannabis oil in her luggage. >> it's been very, very stressful, and very traumatic to my mental psyche, being away from my family. >> reporter: the state department calling the case a sham, and urging russia to negotiate for griner's release,

and american paul whelan as well. >> we are in constant contact with russian authorities to get brittney and others out. and so far, we've not been meeting with much positive response. but we're not stopping. >> reporter: the u.s. has offered to exchange a russian arms dealer named viktor bout for griner and whelan's release. griner held since february. whelan since 2018. >> and so martha, of course, the question, where does the legal fight go from here? does the legal fight continue? will she have to serve this time? and for so many americans back home here wondering, are the russians taking advantage of her fame, her wnba status here, given, of course, the tensions between the u.s. and moscow right now? >> reporter: david, the russians are certainly taking advantage of griner's fame, and she could appeal further, but tonight, the state department is saying they are hopeful that the conclusion of today's court session will now unlock the next step in negotiations. david? >> let's hope. martha raddatz tonight. martha, thank you. meantime, to the war in

ukraine. president biden with a warning to russia tonight about its claims that ukraine is planning to detonate a so-called dirty bomb, a conventional explosive laced with radioactive material. the president was asked today, does he believe it's a false flag operation, meaning that it could actually be russia preparing to deploy a dirty bomb? here's what the president said. >> let me just say, russia would be making an incredibly serious mistake for it to use a tactical nuclear weapon. i'm not guaranteeing you that it's a false flag operation yet, don't know. but it would be a serious, serious mistake. >> so, let's bring in our senior white house correspondent mary bruce, live at the white house tonight. mary, you pressed the white house about the potential consequences for russia here. the administration obviously walking a fine line. they don't want to enflame the situation, but they are signaling through the white house and through the state department, the pentagon, that they've sent a message to the russians about possible consequences here?

>> reporter: david, the press secretary telling me that in private conversations with moscow, they have made it very clear, there will be consequences if russia uses a nuclear weapon or a dirty bomb. though they won't say what those consequences would be. the white house continues to stress that russia is falsely accusing ukraine of preparing to use a dirty bomb. the concern, of course, is that russia often accuses others of what it intends to do. but right now, the administration says they have seen no indication that russia has made a decision or intends to use a nuclear weapon or dirty bomb. but they are, of course, watching this very, very closely. david? >> along with the rest of the world here on this one. mary bruce tonight, thank you. now, to election night, two weeks from tonight. of course, abc news live coverage on election night right here. but before we get there, the high stakes debate tonight. all eyes on pennsylvania's senate race, the race that could decide who controls the senate, the democrats, of course, or the republicans. tonight on stage, democrat lieutenant governor john fetterman going head-to-head with republican dr. mehmet oz. fetterman still recovering from a stroke nearly six months ago.

abc's rachel scott in harrisburg for the debate tonight. >> reporter: democrat john fetterman tonight trying to prepare pennsylvania voters for a senate debate like no other. it's been six months since the candidate suffered a stroke. tonight's questions will be closed captioned on big screens, so he can read them to help with lingering auditory processing issues that doctors say are normal in recovery. >> some people might be -- they were maybe critical about it, or like, what's going on here? i would remind people that half of americans use captioning when they watch television or whatever. >> reporter: the campaign trying to lower expectations, saying to expect "awkward pauses, missing some words, and mushing other words together," noting a tv studio is the "comfort zone" of fetterman's republican rival, dr. mehmet oz. oz has made an issue of fetterman's health. >> when i'm asked, "is he improving or not," i don't know, because nobody knows. >> reporter: but tonight, the

republican expected to laser in on one issue -- crime. >> the fabric of our community is being shredded. it's under assault. >> reporter: fetterman's task tonight -- to convince voters he's tough on crime, and that his stroke has given him new insight into what americans are going through. >> now, after having that stroke, i really understand, you know, much more, kind of, the challenges that americans have day in and day out, because health care saved my life. >> and rachel scott with us live here tonight. rachel, you'll be right here with me on election night. also right here, our partners at fivethirtyeight. and as you know, rachel, they've done the math here. some telling numbers. right now, they give democrats about a 52% chance of holding onto the senate. if john fetterman beats dr. oz, fetterman with a slight lead right now, then democrats chances of keeping the senate go up to 73%, that's a dramatic uptick there, the campaign obviously aware of the stakes for the lieutenant governor tonight. >> reporter: yes, david. and this is a campaign that is also well aware of just how unusual the circumstances are here. not only is control of the senate on the line, but also their candidate is still recovering after suffering a stroke. but dr. oz facing his own set of

challenges. he is one of the most famous television doctors, but his campaign has been under scrutiny for how they've criticized and attacked john fetterman's health. and tonight, dr. oz will be under immense pressure to strike a more thoughtful tone. david? >> rachel scott, we'll be watching right here with you. thank you, rachel. now, to the growing backlash to kanye west's offensive and anti-semitic remarks. tonight, the biggest corporate sponsor, adidas, has now ended the partnership. tonight, the german-based company and what they're now saying. here's matt gutman. >> reporter: tonight, kanye west's billion dollar empire collapsing, with adidas, gap, and universal music all cutting ties with the rapper known as ye. gap removing yeezy products from its stores and shutting down the website. adidas, based in germany, ending weeks of silence, dropping it's single-most valuable collaborator, following anti-semitic rants in multiple

interviews. ye even taunting adidas on the "drink champs" podcast last week. >> i can say anti-semitic things and adidas can't drop me. now what? now what? >> reporter: adidas today with an answer, saying in a statement it "does not tolerate anti-semitism and any other sort of hate speech," adding ye's recent comments and actions have been "unacceptable, hateful and dangerous." >> and we know, from all the research, that hateful messages lead to hateful actions. and hateful incidences lead to hateful crimes. >> reporter: the move expected to cost adidas nearly $250 million in profit this year. the world jewish congress applauding adidas' action, but not its delay, saying in a statement the company's history "is not disconnected from the dangers of anti-semitism. during world war ii, its factories produced supplies and weapons for the nazi regime." david, jewish community leaders telling me the cascade of companies severing ties with ye can't stop him from talking. what it can do is show that
