Late Saturday night news broke that Glee star Cory Monteith was found dead in a Vancouver hotel room; he was 31 years old. Vancouver police say there were no indications of foul play at the scene, and we won’t know further details until the autopsy is released Monday. [Update: According to the British Columbia coroner’s office, he died of a “mixed drug toxicity, involving heroin and alcohol.”] Monteith, who played Finn Hudson on FOX’s Glee and broke out as one of the series’ biggest stars, had checked himself into rehab earlier this year to address substance addiction. He was expected to make a full recovery and return in the fifth season of the musical dramedy.

On Sunday the network FOX, the studio 20th Century Fox Television, and Glee producers released a joint 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.”

As a self-processed Gleek, news of Monteith’s passing is shocking and incredibly sad. He contributed so much energy, enthusiasm, and emotion to the show’s grade-A pilot and quickly became a standout fan-favorite. Last we saw his character, Finn left McKinley High to pursue a teaching degree; I was hoping to see Finn eventually return to teach at the high school and run the Glee club when Mr. Shue was ready to move on. Also, Finn always had an undeniable connection with Lea Michele’s Rachel Berry and Gleeks around the world had been anticipating the two to get back together and sing ride off into the sunset come series end.

However the producers address Cory’s passing, I’m sure it will be heartfelt and enduring. RIP Cory Monteith.
