Man shot ex-girlfriend then himself, investigators say

An Atascadero man shot his ex-girlfriend, then shot himself in last week’s murder-suicide near Santa Margarita, investigators said Tuesday.

Further investigation into the events leading up to the discovery of two bodies found Dec. 1 off Highway 58 near Red Hill Road shows that the woman was the victim.

Authorities believe Stephanie Rodriguez, 19, of Templeton was driving her car with her ex-boyfriend, Hugo Enrique Serrantos Castillo, 22, of Atascadero in the passenger seat.

Investigators think Castillo shot a gun several times in the car, according to officials. The car then rolled down an embankment.

Castillo apparently got out of the car after it came to a stop and shot himself. He died of a single gunshot wound.

Officials do not believe Rodriguez fired any shots.

Investigators did not say where or how many times Rodriguez was hit. Forensic evidence, ballistics and autopsy results confirmed the scenario, authorities said.

Investigators are doing additional forensic work and awaiting a toxicology report, officials said. Results are expected in two weeks.

A supervisor at Cornucopia Tool and Plastics, the company where Rodriguez worked, said she and Castillo had been dating for about three years and that Rodriguez had broken up with him about three months ago.

He had been trying to get back together with her, the supervisor said, adding that Castillo would call, send text messages and try to arrange to see her.

Rodriguez was reported missing to the Atascadero Police Department about five hours before the bodies were found in the early morning hours of Dec. 1.

Rodriguez was said to be “possibly at risk,” according to police logs.

Sheriff’s officials Tuesday said there’s no evidence to support that she was kidnapped, and the investigation into what happened is ongoing.
