Police are investigating the death of Peter Lopez as a possible suicide.
Officers were sent to the couple's Encino Hills home in the 15900 block of Woodvale Road at around 11:30 a.m. after receiving reports of a shooting.
A spokesman for Lopez's law firm says he was Michael Jackson's music attorney until a couple years before the pop star died.
Bach is best known for her role as Daisy Duke in the 80s TV series.
Bach's publicist, Steve Rohr, says the Lopez family has suffered a "tragic personal loss."
Bach and Lopez had two young daughters.
