Southern California authorities have arrested the adult son of a man and woman who were fatally shot in their luxury home in February.

The Orange County Sheriff's Department said Friday that 19-year-old Ashton Sachs was arrested and booked for investigation of murder and is being held without bail. Authorities say Sachs is a college student in Washington state and lives in the Seattle area.

Bradford Sachs and Andra Sachs were found shot to death last month inside their nearly 9,000-square-foot San Juan Capistrano house. Their 8-year-old son was also shot but survived.

Authorities found no signs of a break in.

The couple, who had five children, filed for divorce more than a decade ago but continued to live and conduct business together.
