Jesse tuned the radio to a local news broadcast, which reported, "Breaking news: a horrific scene with multiple victims. It started when neighbors reported hearing hundreds of gunshots fired. When Albuquerque police arrived, they discovered the bodies of nine male victims, many shot multiple times." The report then went on to detail the officers' reaction to the gruesome scene, describe Walt's trunk gun, and reveal that there was a "person of interest" who "fled the scene" -- but it's the number of bodies that really matters here, confirming that Walt met his end in the Breaking Bad series finale.
Apart from Jesse, there were just eight occupants of the white supremacist compound before Walt came along in the series finale: Todd (Jesse Plemons), Uncle Jack (Michael Bowen), Kenny (Kevin Rankin), Matt (Matthew T. Metzler), Frankie (Patrick Sane), Lester (Tait Fletcher), and two other unnamed members of their crew. We saw all of them die from Walt's attack and the aftermath, but that still leaves one more casualty to bring the body count up to nine: Walt. While this radio report doesn't specifically identify Walt as one of the victims of this "massacre," he was the only other person there. And it wouldn't be a Breaking Bad story if the teaser didn't trust audiences to do some basic calculations to confirm Walt's fate as the ninth victim.
So, sorry to anyone who might have hoped Heisenberg would survive both a bullet and his terminal illness. There are still plenty of burning questions for the film to answer, though, and we may still get some flashback action featuring Walter White, since the film is will reportedly bring back more than 10 familiar faces from the original AMC series.
El Camino: A Breaking Bad Movie premieres on Netflix on Friday, Oct. 11. The film will also be screened for three days at 68 movie theaters across the country, including locations in New York, Los Angeles, Chicago, and Albuquerque.
