Glee premiered on May, 19, 2009 and was an instant phenomenon, the upbeat musical dramedy brimming with talented, bright-eyed young stars whose anthem upon arrival was "Don't Stop Believin'." Mark Salling played Puck, a bad boy with a good heart (and great voice) who was best friends with Cory Monteith's Finn and was the more reluctant football player of the pair to join the New Directions glee club. But he eventually did, of course.
Monteith died in 2013 of a heroin overdose, a shocking loss for his loved ones and Glee fans around the world. Salling was found dead of an apparent suicide Tuesday, the 35-year-old actor's career over after he was charged with possession of child pornography in 2015. He had pleaded guilty in December and was free on bail while he awaited sentencing in March.
Each lost under wildly different circumstances, both losses such a stomach-churning waste.
