Glee star Cory Monteith's death not caused by substance abuse, reveals autopsy Police in Vancouver have said it is unlikely that Cory Monteith's death was the result of substance abuse. Officials said the Glee star's death remains unclear following yesterday's post mortem examination, and added it could take several days before toxicology test results are complete. Sgt Randy Fincham of Vancouver police said there was nothing to indicate the actor's death was due to illicit drug use. Monteith, 31, known for his role as quarterback-turned-singer Finn in Glee, was found dead in his hotel room in Vancouver shortly after midday on Saturday, when he missed his check out time. He had checked into the hotel on 6 July, and was due to check out on Saturday, Vancouver Police Department acting chief Doug LePard told reporters. Others were in the hotel room with Monteith on Friday night, but evidence including his fob key entries indicated he returned to his room by himself early on Saturday and was alone when he died, police said. Coroner Lisa Lapointe said: "We do not have a great deal of information as to cause of death." Monteith, who had played front man and heart throb Finn Hudson since the hit show began in 2009, had been treated for drug addiction and reportedly had a history of substance abuse. In March he voluntarily entered a rehabilitation facility for an unspecified substance addiction. He had also received similar treatment when he was 19, and spoke openly about his addiction struggles, saying he had a serious problem and took "anything and everything." His girlfriend and Glee co-star Lea Michele yesterday said she was "devastated" by the news and asked people to respect her privacy following Monteith's death.
