Glee star, Cory Monteith, who was found dead on Saturday in a Vancouver hotel room, died of a "mixed drug toxicity" of heroin and alcohol, reports the British Columbia coroner.

"At this point there is no evidence to suggest Mr. Monteith's death was anything other than a most-tragic accident," the BC Coroners Service stated on Tuesday.

The cause of death was determined by an autopsy and toxicology tests. An investigation continues.

The Coroners service also added that, "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."

In April, the 31-year-old Canadian actor, who was dating Glee costar Lea Michele at the time of his death, completed a month-long stint in a treatment facility for substance abuse.
