AUSTIN (KXAN) — An 18-year-old was arrested in connection with a man’s shooting death that occurred in southeast Austin last Thursday, March 17. Court documents said the 18-year-old suspect claims the shooting happened in self defense.
According to an Austin Police Department incident report, Omar Martinez-Desiderio was arrested related to the murder, which took place in the 6500 block of Porter Street. That’s off Montopolis Drive.
On March 24, APD identified the man killed as Alberto Cortes-Rodriguez, 42.
Records from Travis County Jail show Martinez-Desiderio was booked the day the homicide happened, just after 9:30 p.m. He’s being charged with first-degree murder. Bond is set at $125,000 for that charge.
Last Thursday, police said a man who was shot multiple times was found next to a motorcycle. He was pronounced dead at the scene just before 6 p.m. On March 18, the medical examiner did an autopsy and determined the official manner of death was homicide.
Witnesses told police a motorcyclist and a resident had a prior verbal argument. The suspect, now identified as Martinez-Desiderio, came out of his home after being told the motorcyclist had almost run over his dog. After another argument, Martinez-Desiderio reportedly shot the motorcyclist and ran back home, APD said.
According to an arrest affidavit, Martinez-Desiderio told police the victim had threatened to kill his entire family during a previous verbal argument one month prior to the shooting.
When Martinez-Desiderio confronted Cortes-Rodriguez about almost running over his dog, he told police he cursed at the driver as he rode away. Martinez-Desiderio then said Cortes-Rodriguez turned around and began riding back in Martinez-Desiderio’s direction.
According to the affidavit, Martinez-Desiderio said he jumped out of the way and saw the driver reach for something in his pocket. That’s when Martinez-Desiderio pulled his gun and shot the motorcyclist “17 times,” the affidavit said.
Martinez-Desiderio told police he left the scene and threw his pistol in a field behind his home, the affidavit said.
Police said Martinez-Desiderio had an outstanding felony warrant for aggravated assault.
APD said this is the city’s 17th homicide for the year. Detectives ask anyone with information or video of the shooting to call APD Homicide at (512) 974-TIPS.
