LOS ANGELES — Lee Thompson Young, who began his acting career as the teenage star of the Disney Channel’s ‘‘The Famous Jett Jackson’’ and was featured in the film ‘‘Friday Night Lights’’ and the series ‘‘Rizzoli & Isles,’’ was found dead Monday, police said. He was 29. There was no official cause of death, but Mr. Young’s manager, Paul Baruch, said the actor ‘‘tragically took his own life.’’
In the TNT series, Mr. Young played fledgling police Detective Barry Frost, who is computer savvy but squeamish. Earlier Monday, the channel announced it was renewing the series that stars Angie Harmon and Sasha Alexander.
According to a biography from TNT, Mr. Young was inspired to pursue acting when, at age 10, he played Martin Luther King Jr. in a play in Mr. Young’s hometown of Columbia, S.C. In 1998, Mr. Young began starring in ‘‘The Famous Jett Jackson,’’ playing a TV action hero who returns to his roots for a less high-profile life.
Mr. Young followed it with roles in TV series, including ‘‘The Guardian,’’ and in the films ‘‘Akeelah and the Bee’’ and ‘‘The Hills Have Eyes II.’’ He joined ‘‘Rizzoli & Isles’’ when it debuted in 2010.
