“Mark took Cory’s death extremely hard and never got over it,” a source told Us Weekly of Monteith’s July 2013 death, which was due to an accidental drug and alcohol overdose.
Another source added, “He was so heartbroken and hurt by Cory’s death and that he didn’t ask for help and he was vocal about those feelings.”
Monteith, who starred alongside Salling on the FOX hit for four seasons, was 31 years old and completed a stint in rehab for his struggles with substance abuse just months before his tragic death.
As previously reported, the Los Angeles Police Department confirmed Salling’s death to Us on Tuesday. The 35-year-old actor’s body was found by a riverbed in the Sunland-Tujunga neighborhood of Los Angeles. Salling, who had pleaded guilty to charges of possession of child pornography in December, was set to be sentenced on March 7. He previously agreed to a plea deal, which included four to seven years in prison.
