"Glee" star Cory Monteith died of a "mixed drug toxicity" which included alcohol and heroin, the British Columbia coroner's office said Tuesday, the New York Times noted.

"At this point there is no evidence to suggest Mr. Monteith's death was anything other than a most-tragic accident," the office said in a statement.

"Mr. Monteith's family has been made aware of the circumstances surrounding the death. On behalf of family members, the BC Coroners Service asks that the media respect their privacy at this difficult time," the statement added.

Monteith, who played Finn Hudson on the hit Fox musical-comedy series "Glee," was found dead in his hotel room in Vancouver, British Columbia, on Saturday afternoon. Monteith, 31, had struggled with substance abuse problems, having voluntarily checked himself into a rehabilitation facility in March. He also received treatment when he was 19.

The Daily Mail reports on claims that Cory Monteith lived a "double life" - he worked hard in Los Angeles on his television career and partied hard and abused drugs while in his native Canada. Monteith had been seen spotted earlier in the day with his friends, but video surveillance from the hotel showed that he returned to his bedroom alone early Saturday.

The Fox network and the producers of "Glee," including 20th Century Fox Television, have called Monteith an exceptional performer "and an even more exceptional person."

His on-screen and real-life girlfriend Lea Michele, is said to have been "devastated and shaking" following the tragic news. The actress has asked for privacy in the wake of his death.

Fox network is in talks regarding changes to next seasons "Glee."  Monteith had been expected to play a major role in the first two episodes of the series next fall.  His character, Finn, had worked through a major story line last season, despite graduating from the show's high school the year before.
