BROTHERS & SISTERS star Balthazar Getty hit the streets of Los Angeles on Wednesday night (13Oct10) to appeal for help in a missing persons case.
The actor walked around the city handing out leaflets in a bid to track down a "mentally challenged" man who has been missing for nearly two years.
The man, named only as Rocky, is the son of one of Getty's friends and the actor hopes the public will be able to help locate him.
He is described as in his 40s, around five foot five inches tall, with brown hair and hazel eyes, according to TMZ.com.
Rocky was last spotted in west Los Angeles a year ago.
