Latest on Cory Monteith Death

Cory Monteith entertained millions as the singing football player "Finn Hudson" in "Glee." Sadly, his voice was silenced on Saturday when the 31-year-old actor was found dead in a Vancouver hotel room, CNN's Nischelle Turner reports.

As Canadian authorities investigate what killed him, his on and off-again girlfriend and "Glee" costar, Lea Michelle, is grieving privately. In a statement her rep asked "that everyone kindly respect Lea's privacy during this devastating time."

Unlike his clean-cut character "Finn Hudson," Monteith had a troubled youth. He described himself as an "out of control" drug and alcohol-abusing teen.

Despite all the success from "Glee," Montieth continued to battle substance abuse, even checking into rehab earlier this year. His friend, "Glee" director Adam Shankman, spoke to Monteith hours before he was found dead.

"I had several interactions with him yesterday where he said he was feeling amazing and even said I'm feeling fantastic again," says Shankman.

Monteith's autopsy is being conducted today. Check out CNN.com for developments.
