"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 said in a statement released July 16. "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 cause of death was determined by an autopsy and toxicology tests. An investigation continues.
The actor was found July 13 at Vancouver's Fairmont Pacific Rim Hotel. He checked into the hotel July 6, and was expected to check out July 13. When Monteith missed his checkout time at noon, hotel staff went to his room and discovered his body. Police ruled out foul play early on.
Glee executive producers, producers 20th Century Fox Television and Fox Broadcasting Co. said in a previous statement: "We are deeply saddened by this tragic news. 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."

The actor, according to his representative, "ha[d] voluntarily admitted himself to a treatment facility for substance addiction. He graciously asks for your respect and privacy as he takes the necessary steps towards recovery."
Monteith had previously entered rehab at 19 years old.
