It’s hard to know what others are facing in their personal lives. Canadian actor Cory Monteith was living what seemed like a happy life. He was the star on a popular sitcom, has fans all over the world and seemed beloved, but he struggled with demons stemming from his dark past. Monteith has been candid about his struggles with drugs and alcohol and confessed that he started using drugs when he was 13 years old.  When his death was first reported, everyone feared the worst. Initially the cause of death was not determined because an autopsy was needed, but now it has been revealed. Coroners have said that Monteith’s death was caused by “a mixed drug toxicity, involving heroin and alcohol”. Monteith had checked himself into rehab in April.

The 31 year old actor gained his fame by playing the school jock, Finn Hudson on Fox Network’s Glee. His Glee costars have taken to twitter to express their condolences. “I have no words! My heart is broken. Cory was not only a hell of a friend he was one amazing man that I will hold close to my heart forever,” said Dot-Marie Jone, who plays Coach Shannon Bieste. Nene Leakes, who plays Coach Roz posted a photo of herself with Monteith and this caption, “There were fun times! I hate 2 see such a great young actor leave us so soon! RIP @corymonteith my prayers r wit u.” His TV show girlfriend turned real life romance, Lea Michele requests privacy at this time.

The coroners who discovered the deadly concoction, have determined that this mixture was not intentional. “At this point there is no evidence to suggest Mr. Monteith’s death was anything other than a most tragic accident,” they said in a statement earlier today. No other information was available at this time, but further investigating is needed.
