Authorities are investigating what prompted a man to allegedly beat his wife to death before hanging himself in their Santa Clarita backyard.

The Los Angeles County Sheriff's Department has identified the couple as 51-year-old Gioacchino Perrotta and his 47-year-old wife Giuliana. Investigators say the couple were going through a divorce but have not released any details about what preceded the killings.

Deputy Lillian Peck says a family member found the woman dead in her home Sunday morning and called deputies, who found the husband's body.
