On his flight to Vancouver earlier this month, Cory Monteith recorded a video message for a young fan, telling her to "stay out of trouble and stay in school." This is believed to be the last video of the 31-year-old Glee star, who died on July 13 from a lethal overdose of alcohol and heroin.

A flight attendant named Sheila apparently asked Monteith to record a quick video for her boyfriend's daughter Mallory, and the star happily obliged. Just a few days later Monteith was found dead in his room at the Fairmont Pacific Rim Hotel in Vancouver, and on Tuesday the British Columbia Coroner's Service stated, "At this point there is no evidence to suggest Mr. Monteith's death was anything other than a most-tragic accident."

The news broke last Saturday evening, which was around the same time Monteith's Glee co-star and girlfriend Lea Michele found out. Monteith's body was found just after noon, and though a pal had been trying to call Michele all day, it wasn't until around 10pm that they were finally able to reach her.

"Lea completely lost her mind," a source tells Us Weekly. "She went crazy, screaming and crying until 3 a.m. ... Lea has been inconsolable and feels like she's been hit by a truck. She didn't know he'd started using again."

Monteith was cremated in Vancouver on Tuesday, and Michele reportedly attended a private viewing with his family. "She's not doing great," another insider said. "She's totally devastated."
