SAN ANTONIO – Brian Lee Morales, 20, has become the second person to face charges in connection with a road rage-related slaying on San Antonio's Southwest Side in August.
San Antonio police took him into custody at a home in the 100 block of Amber Valley late Thursday night.
A charge of murder later was filed against him, and he was booked into jail Friday morning.
Sgt. Javier Salazar, a spokesman for SAPD, said detectives believe he was the trigger man in the Aug. 24 shooting death of Casey Blanton, 23.
Salazar said Blanton, who was driving his own vehicle, was shot in the head after a confrontation with Morales, a passenger in another truck.
"There is witness information from that night that indicated that they were driving around aggressively, trying to initiate some sort of conversation with someone," he said.
In November, police arrested another man, Adam Morales, 18, and identified him as Blanton's killer.
Salazar said now, detectives have changed their minds.
"Witnesses started coming forward with further information that indicated that (Brian Morales) is the shooter," Salazar said.
Adam Morales, however, still faces the same murder charge. Police said it appears that the two men, who are related, both were involved in the death.
Salazar said Brian Morales had been the subject of a recent Crime Stoppers report, that he originally was wanted on drug and weapons charges, including possession of a machine gun.
As they began to receive tips on that case, he said, homicide investigators also developed leads, pointing them to him as the suspected shooter in the Blanton case.
It's possible even more people were involved, Salazar said.
"We are still looking for the possibility that there may have been other passengers in this vehicle we'd like to speak to," he said. "It's still too early to tell whether they are suspects in this case. But at this point, they are persons of interest."
Anyone with information is asked to call the San Antonio Police Department, or Crime Stoppers at 210-225-TIPS (8477).
