Lee Thompson Young, a former Disney Channel star who appeared on "Rizzoli & Isles," was found dead this morning at the age of 29.

Young appeared in Jamie Foxx's "Redemption: The Stan Tookie Williams Story" and in the "Friday Night Lights" movie as Chris Comer. He also landed guest roles in TV shows including "The Guardian," "South Beach," and "Smallville."

In 2009, Young starred in the short-lived sci-fi drama "FlashForward" as an FBI agent who commits suicide to prevent a death.

He was Cyborg on Smallville. This is sad. He was so young.

He has an autograph card in Smallville Season Five.

Haven't read why he might want to take his own life. He was still working, maybe not a star. Such a shame, RIP young man.

I *just* saw this on the news. Really liked his character on R&I.
Sad. RIP.

Johnny Lewis also had a Smallville autograph card in the Season 5 set and he died young, too, but only after killing an elderly woman and her cat and then either falling or jumping to his own death from a rooftop last year.

Lee Thompson Young, it appears, committed suicide with a gun and took no one with him, so there's that at least. Sad news, to be sure.

Johnny Lewis also signed for AVP Requiem, as well as Smallville. He had a history of drugs and was likely going through a psychotic episode when he killed his landlady and fell to his death.

The small news articles I read about Young offer no explaination for his suicide. Everyone seemed to like him and were stunned, as he was still filming this season's Rizzoli & Isles. Very sad, but you never really know what's going on in someone's life.
