Canadian authorities said that they would carry out this Monday an autopsy on the body of Cory Monteith, to discover the TV series 'Glee' actor's cause of death, who was found in his hotel room in Vancouver on last Saturday.

Cory Monteith, who gave life to the student Finn Hudson in the musical comedy 'Glee', had decided in April to get admitted voluntarily into rehab to treat his addiction to drugs.

It was the second time the 31 years old actor joined an institution to combat addicition. The first time was when Cory was 19.

It's such a shame that Cory has passed away at this age. Our prayers go out to his family, friends and relatives. 'Glee' is now mourning.
