Stanislaus County sheriff’s deputies continue to investigate an apparent murder-suicide that claimed the life of two men and are still waiting to speak with the woman who survived the attack.

Authorities believe Mario Martinez, 39, shot wife Maricela Martinez, 38, and Modesto resident Mario Medina, 46, along a country road north of Newman on Saturday night before turning the gun on himself.

Both men died at the scene, but Maricela Martinez was found alive and taken to a hospital. She is expected to survive.

Deputy Anthony Bejaran said detectives have not determined what motivated the shooting. Because of her condition, they have not been able to talk to Maricela Martinez, he said.

All three worked for the U.S. Postal Service, according to spokesman Gus Ruiz. Medina worked at the Newman post office along with Maricela Martinez, a carrier. Mario Martinez worked as a carrier for the Livingston post office.

Maricela Martinez filed for divorce in November, according to court documents.

Mario Martinez called authorities at 7 p.m. Saturday, admitted he had shot two people, and then hung up his phone.

Sheriff’s investigators do not know why the trio was at that rural location; they were found next to two parked cars midway between Crows Landing and Newman, near Kilburn and Villa Manucha roads.

Family members of the victims declined to comment or could not be reached Monday.
