Investigators have released the names of the 41-year-old man and the 3-year-old boy shot dead in Starr County on Sunday.

The Starr County Sheriff’s Office identified the deceased as Hector Garcia Jr., 41, of Rio Grande City and his 3-year-old son, Julian Garcia. They were found near the intersection of Woods Brothers Road and Segunada Road north of Rio Grande City.

As CBS 4 News previously reported:

At about 6:10 p.m., the Starr County Sheriff’s Office responded to a shooting on Woods Brothers Road, according to information provided by Maj. Carlos Delgado, a spokesman for the Sheriff’s Office.

Deputies found a man and a 3-year-old child with gunshot wounds, Delgado said. The man was pronounced dead at the scene and the 3-year-old child later died of unspecified injuries.

District Attorney Omar Escobar said the man and the 3-year-old boy were inside a vehicle when they were shot with a “high powered rifles.”

“At this early stage of the investigation, it is difficult to speculate on any motives,” Escobar said in a text message. “However the known facts seem to be consistent with shootings commonly associated with narcotics trafficking.”

Investigators haven’t determined the motive for the shooting, but they’re following several leads, according to the Sheriff’s Office. Investigators believe Garcia and his son were “gunned down by several individuals driving a newer model blue Ford 4 door F-250 pick up.”

Anyone with information is asked to call the Sheriff’s Office at (956) 487-5571.

Correction: The suspects were driving a blue Ford F-250 truck.
