(SELMA, Texas) — A man initially interviewed as a witness at the scene of a murder has now been arrested over a year later in the apparent road rage slaying, authorities in Texas announced.
Jacob Daniel Serna, 29, was arrested on Thursday for the murder of Joseph Banales, according to police in Selma, located about 20 miles outside of San Antonio.
The case began on April 15, 2023, when Selma police said they responded to a single-car crash and found Banales shot in the head and slumped over his steering wheel.
Banales, a nursing student and Army ROTC member at the University of the Incarnate Word in San Antonio, was declared dead at the scene, police said.
Witnesses said Banales tried to merge into another lane and almost hit a dark blue or black sports car with a loud exhaust system, according to the probable cause affidavit. The sports car slowed down, then spend up along the driver’s side of Banales’ car, witnesses said. Then Banales’ car swerved into another lane and crashed into the center median, and the sports car fled, according to the probable cause affidavit.
Banales was on the phone with his girlfriend at the time; she told police she heard what sounded like a loud exhaust system driving by quickly, then a crash, the document said.
Serna and his wife were at the scene when officers arrived, police said. Officer dashboard camera captured Serna standing over Banales’ body, the probable cause affidavit said.
Serna — who drove a blue Ford Mustang sports car — and his wife were interviewed several times, and their stories changed over time, according to police.
Initially, Serna’s wife told police she saw a blue sports car — similar to the color of their car — in the lane next to Banales, the probable cause affidavit said. Serna told police he didn’t see anything and his wife saw the crash, according to the probable cause affidavit.
This July, police interviewed Serna’s wife again. The Sernas are now separated, according to the probable cause affidavit, and she said her husband had sped up to get a better look at the potential suspect’s car, but the suspect’s car was driving too fast, and that’s when the crash happened, the document said.
On Thursday, police interviewed Serna’s wife again. She admitted her husband shot the victim after her husband “became angry that Banales had nearly changed lanes into his blue Mustang,” police said in a statement on Friday.
She said her husband pulled his pistol out of the glove box, loaded the weapon and fired, according to the probable cause affidavit.
She said she made her husband turn around and drive back to the scene, according to the probable cause affidavit.
During the investigation, police zeroed-in on cellphone records to help determine “who could have been driving a blue sports car at the crime scene,” police said in a statement.
The probe, which included searching license plate reader databases, “revealed only one vehicle matching the description of a blue sports car with loud exhaust” — Serna’s car, police said.
“Google Geo-Fence records show Serna’s Google activity pinging in the area at the same time investigators believe the shooting happened,” police added.
Serna has been booked into the Bexar County Jail, police said.
