"It is with great sadness that I announce that Lee Thompson Young tragically took his own life this morning," said Young's long-time manager Jonathan Baruch in a statement.
"Lee was more than just a brilliant young actor, he was a wonderful and gentle soul who will be truly missed. We ask that you please respect the privacy of his family and friends as this very difficult time."
Young began his acting career early, appearing in community theater as a child before heading toward the bright lights of New York City. There, he auditioned for and won the main role in Disney's "The Famous Jett Jackson." The show lasted for three seasons and a TV movie.
After the end of the series, 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.
His latest work was in TNT's "Rizzoli & Isles" as Det. Barry Frost, Rizzoli's (Angie Harmon) partner.
Young graduated with honors from the University of Southern California.
