Anthony Paz Torres wanted revenge for Islamic State-linked shootings in Garland and California when he fired on a Pleasant Grove tire shop owned by a Muslim man, killing one and injuring three others.

A Dallas County jury convicted Torres of murder Friday after three days of testimony. Torres faces up to life in prison.

Torres, 33, went to Omar's Wheels and Tires in Pleasant Grove on Christmas Eve 2015 planning to kill Muslims, but instead he killed an innocent bystander in what prosecutors called a terrorist attack.

Enrique Garcia-Mendoza, 25, was sitting in the passenger seat of his friend's car when a bullet pierced his neck, killing him within minutes.

Jurors watched surveillance footage from the Dec. 24, 2015, shooting, as well as a confrontation involving Torres a week earlier at the tire shop.

Torres went to the shop on Dec. 17 asking who the Omar in the business's name was. The business is owned by Omar Omar, whose last name is the same as his first.

Several employees said Torres ranted and cursed Muslims. Surveillance footage shows him, wearing a yarmulke, waving his arms and pacing around, appearing to be yelling. One of the shop workers starts to chase him and kick at him but others pull him back.

Several men can be seen gesturing for Torres to leave.

When officers went to Torres' house after the incident, he claimed that the tire shop employees kicked him. He said that he is "Jewish and Christian."

"Muslims are here in this country and profiting off Christians," he said. "I was born here."

The officers told Torres not to go back to the tire shop. He continued to talk as they walked away.

"They should be second-class citizens," Torres said of Muslims.

Prosecutors Clinton Stiffler and Herschel Woods argued that Torres intended to kill on the day of the shooting. He went to the shop armed and fired directly at the people there.

"He adopted a cause. He radicalized," Stiffler said. "Terrorism. That's what this was."

Jurors also listened to a jailhouse phone call in which Torres said Muslims "kill people in Garland and San Bernardino."

Fourteen people were killed and 22 others were wounded in a mass shooting Dec. 2, 2015, in San Bernardino, Calif., that authorities called a terrorist attack by a couple affiliated with the Islamic State.

Seven months earlier in Garland, two men opened fire on a prophet Muhammad cartoon contest in an ISIS-inspired attack. One person was injured before a Garland police officer returned fire, killing both shooters.

But Garcia-Mendoza, a tattoo artist who went by the nickname Kike, knew nothing about Torres and his ranting at the shop while he waited in a car for his friend's tire to be fixed. One witness said Garcia-Mendoza had been eating fries when the shooting started.

Bullets pierced the rear windshield of the car where Garcia-Mendoza sat, clipping the headrest before hitting him in the neck. A Dallas County medical examiner said the bullet cut across his spinal cord and hit an artery.

Another bystander and a tire shop employee were clipped by bullets, and another employee was seriously injured in the shooting.

Maher Yousef remembered when Torres came to the shop a week before the shooting on Dec. 17, 2015. He said he needed air in his tires. Instead of getting air, Torres started cursing about Muslims.

"What are you doing here, you Muslims?" Torres asked, according to Yousef.

Yousef said he didn't understand English as well then but could still tell that Torres was "cursing, constant cursing."

Yousef, who is Christian, fled from Iraq to the United States.

"They were killing Christians there," he testified in Arabic through a translator.

Surveillance footage shows Yousef continuing to work Christmas Eve while Torres paces in the parking lot. Torres then pulls a gun and starts shooting toward the tire shop. Yousef was the first to be shot. He collapsed and rolled under the bed of a truck.

About 80 percent of Yousef's pancreas was removed. He no longer has a spleen, and his liver was damaged.

"This time I can't eat without a pill," he said.

After Torres finished firing, he hopped in his car and started to drive off, but the tire shop's owner grabbed his own gun and shot into Torres' car to try to stop him from leaving.

Torres was wounded by Omar but still managed to drive off.

Defense attorney Christopher Mulder argued that minutes missing from the surveillance footage created doubt about who shot Garcia-Mendoza. He said Omar was trying to cover up for the fact that his own bullets could've killed the bystander or that a third shooter could've fired from inside the shop.

"Don't guilt yourself into finding [Torres] guilty when the evidence is not there," Mulder told jurors.

But Stiffler argued that Omar was trying to call police after Torres' rant and that no one else fired a gun that day.

"There's no phantom aggressor. There is no third shooter," he said. "This is not a conspiracy."

Jurors returned with a guilty verdict in an hour.

Omar, 33, is a Kurdish-Iraqi-American but said not everyone who works at his shop is Muslim. He said he planned to close early the day of the shooting and give his employees their Christmas bonus before they got a day off for the holiday.

He said no one touched or tampered with the surveillance footage. He said they didn't touch any of it until the detective showed up.

"We didn't delete nothing," he said.

The footage shows everyone run around from the area where the shooter was and Omar running toward the shooting.

"Nobody had a gun but Omar," he said of his employees.

Omar disputed the possibility that a bullet from his gun could've arced and hit Garcia-Mendoza.

"Tell me what gun make a U-turn. I buy it," he said.

Omar was not charged with a crime for shooting at Torres.

"If someone comes in your door and try to shoot everybody, what would you do? Try to self-defend," Omar said.

After Omar testified, he gestured to the victim's family as he left the courtroom and said, "Sorry about your family."

Torres' sentencing hearing before State District Judge Teresa Hawthorne has not yet been set.
