Next on NBC 5 at 10: New documents released by police offer more information in the investigation of a triple murder in Garland.
Richard Acosta, who surrendered to police a day after the shooting, remained in Dallas County jail Tuesday on $3 million bond.
Police said the shooter fired more than 20 rounds from a .40-caliber pistol before fleeing in the Dodge Ram pickup driven by Acosta, who they said also brought the shooter to the gas station. Harris said the son was hysterical when he ran back to the pickup and the father drove them home. The son then got into a car and fled, Harris said.
Police named those killed in the shooting as 14-year-old Xavier Gonazalez, 16-year-old Ivan Noyala, and 17-year-old Rafael Garcia. A 15-year-old who was a cook at the store was taken to the hospital following the shooting and was expected to survive.
