Affidavit: Warrant issued for man who allegedly shot, killed ex-girlfriend's new boyfriend

AUSTIN (KXAN) -- The Travis County Sheriff's Office issued an arrest warrant for a man deputies said shot and killed a man at a bar in southeast Travis County early in the morning of Friday, May 3, according to court documents.

TCSO said the homicide happened at a business located in the 5600 block of South U.S. 183, which is close to Austin-Bergstrom International Airport. Deputies said they initially responded to a call there at about 12:25 a.m. for reports about a “disturbance involving a gun,” according to a news release.

Deputies said they found a man dead in the parking lot with several gunshot wounds.

The sheriff’s office reported that witnesses saw the suspected gunman drive from the scene northbound on U.S. 183 in a white Ford two-door pickup truck with a toolbox in the truck’s bed. They also released photos and a description, saying he is Hispanic, in his 20s-30s and last seen wearing a white short-sleeved polo, jeans, white Nikes with a black swoosh and a white ball cap over a blue durag.

The suspect was identified in an affidavit for an arrest warrant as Cesar Marquez, 32. He faces a charge of first-degree murder.

Several witnesses talked to deputies, one of them was the victim's girlfriend, who told deputies she had been dating the victim since January.

Other witness statements revealed that the victim and girlfriend had an argument at the bar after the girlfriend had spoken to her ex-boyfriend, Marquez, according to the affidavit.

The victim then walked outside, and Marquez followed, the affidavit said, and the shooting happened in the parking lot shortly after.

Deputies watched security footage from the bar and corroborated the witnesses' statements, and were able to identify Marquez as the suspect.

A warrant for arrest on a first-degree murder charge for Marquez was filed on May 7. The affidavit stated that his whereabouts were still unknown.
