Employees at the Fairmont Pacific Rim Hotel in Vancouver discovered his body on Saturday night after he didn’t check out at the expected time.
Staff found him alone after reportedly going out with friends, and police have issued a statement that foul play is not suspected.
Monteith, age 31, was the longtime boyfriend of his Glee co-star Lea Michele. Besides his famous role as smooth-voiced Finn Hudson, he appeared in the MTV series Kaya and the 2011 movie Monte Carlo with Selena Gomez.
Many speculate that the cause of death was a drug overdose due to his recent stint in rehab. In one notable interview, the actor admitted that he did “anything and everything, as much as possible.”
