Young's manager confirmed Monday that the actor "tragically took his own life", reports dailymail.co.uk.
"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," said Paul Baruch.
Young's body was found at his North Hollywood home by police Monday morning after he failed to show up for work on the sets of the crime drama "Rizzoli and Isles", police Officer Sally Madera said.
The Los Angeles Fire Department was summoned and pronounced him dead at the scene, she said.
LAPD robbery-homicide detectives and the Los Angeles County coroner office were investigating because it is a high-profile death, she said.
According to TMZ, the actor died from a self-inflicted gunshot wound. Young's death remains a mystery because he did not leave a suicide note.
The former Disney star was last seen on Aug 17 and law enforcement officials believe that the star may have committed suicide that same day.
