Mexican authorities arrested a man on suspicion of killing two expats last summer near San Quintin and then dumping their bodies in a well

Ian Hirschsohn, a 78-year-retiree and 73-year-old Kathy Harvey – both San Diego area residents, were stabbed to death late August of last year, while asleep in bed at Hirschsohn’s longtime vacation home at El Socorrito, a tiny beach town about 130 miles south of Ensenada, the San Diego Union-Tribune reported.

Their families reported the couple missing Sept. 2, and investigators discovered their bodies Sept. 5, according to the newspaper.

Investigators from the Baja California Attorney General’s Office arrested the suspected killer last week. He was identified only by his first name and one initial, Emmanuel N., as is standard in Mexican criminal cases but local sources revealed that his full name is Emmanuel Aguilar Vidaurrazaga.

Hirschsohn’s daughter told the newspaper that the suspect is a member of the family that owns the ranch where her father’s vacation home was located.

She also told the U-T that her father had owned the home for about 35 years and knew the family that owned the ranch, including the alleged killer.

Around the time the bodies were found, prosecutors said they believed the killer was a drug addict and would-be burglar who broke into the home thinking it was empty, according to the U-T. The killer allegedly stabbed the victims inside the home, muscled their bodies into Hirschsohn’s Toyota Land Cruiser and drove about four miles to the well to discard them.
