Updated at 9:46 a.m. Thursday: Revised to indicate the second suspect has been arrested.

Two suspects have been arrested in the fatal shooting of a Dallas teenager in a Garland parking lot Monday.

Edgar Adan Villegas-Torres and Bryan Alexander Ibarra, both 17, were jailed on murder charges in the death of Christopher Cardoza, police said.

Cardoza, 17, died of his injuries at Texas Health Presbyterian Hospital Dallas around 5:30 p.m., police said.

Detectives believe Cardoza and a friend had driven to meet two people in a parking lot in the 3600 block of South First Street in Garland in order to conduct a drug transaction. Cardoza, who was sitting in the vehicle’s front passenger seat, was shot during the encounter, Garland police Lt. Pedro Barineau said.

The driver of the vehicle sped away and took Cardoza to the hospital, he said.

Investigators arrested Ibarra on Wednesday and Villegas-Torres on Thursday. Both were being held in the Garland Detention Center, with bail still pending.
