Friends found a 37-year-old San Carlos man dead late Monday night northwest of Edinburg.

Family members called the Hidalgo County Sheriff’s Office at about 7:30 p.m. Monday to report Anastacio Rocha, 37, of San Carlos hadn’t returned home, said Sheriff Eddie Guerra. They also called OnStar, the vehicle tracking and roadside assistance service, which provided a GPS location for Rocha’s car.

Four friends went to the location near Big Five Road and Mile 14, where they found Rocha dead in the car, Guerra said. Investigators haven’t said where, exactly, Rochas was located in the car when they found him.

Investigators determined Rocha suffered what appeared to be a gunshot wound to the head, Guerra said. The Sheriff’s Office is treating Rocha’s death as a homicide.
