Coroner's office operations chief Craig Harvey says entertainment attorney Peter Lopez died Friday at his home in the Encino Hills.
Assistant Chief Coroner Ed Winter says a neighbor reporting hearing a gunshot and someone at the home found Lopez's body.
A spokesman for Lopez's law firm says he was Michael Jackson's music attorney until a couple of years before the pop star died.
Bach's publicist, Steve Rohr, says the Lopez family has suffered a "tragic personal loss."
Bach played Daisy Duke in the 1980s TV series "The Dukes of Hazzard." She and Lopez had two young daughters.
