"Glee" actor Cory Monteith died on Saturday of an overdose of heroin and alcohol, the British Columbia coroner has announced.

The 31-year-old Victoria native, who had struggled with addiction in the past, was found dead in a Vancouver hotel. Police do not suspect foul play and Monteith is believed to have died alone.
"Post-mortem testing, which included an autopsy and toxicological analysis, found that Mr. Monteith, aged 31, died of a mixed drug toxicity, involving heroin and alcohol," said Barbara McLintock of the BC Coroners Service.
The release pointed out that "there is no evidence to suggest Mr. Monteith's death was anything other than a most-tragic accident."
An investigation is ongoing and a full report will be released at a later date.
Monteith was open about his struggles, and in April he entered a treatment facility for what his representative described as "substance addiction." In 2011, he told Parade magazine that he received help for taking "anything and everything" when he was 19.
On "Glee," Monteith thrived as jock-turned-show choir member Finn Hudson. The tall and charming actor often played leading man -- both musically and, often, romantically -- to Lea Michele's quirky leading lady Rachel Berry. Off the set, the pair had been dating.
"We are deeply saddened by this tragic news," Fox and the hit show said in a joint statement on Sunday. "Cory was an exceptional talent and an even more exceptional person. He was a true joy to work with and we will all miss him tremendously. Our thoughts and prayers are with his family and loved ones."
