AUSTIN (KXAN) — A man is facing charges after allegedly shooting at a woman while they both were stuck in traffic on Interstate 35 in an apparent act of road-rage, according to an affidavit. Aaron M. Lopez, 23, faces an aggravated assault with a deadly weapon charge.

The woman slammed on her brakes for traffic on the northbound frontage road of S. I-35 on Dec. 3, only to hear brakes squealing behind her, officials wrote in an affidavit filed in court. When she looked in her rearview mirror, she could only see the grill of the blue Dodge truck behind her.

The truck honked and sped off to her right, she told police. She merged into the traffic snaking its way onto I-35 at 3:42 p.m. when she saw the truck to her right. The man behind the wheel had rolled down his window and started yelling at her.

“You stupid b—-,” she told police he shouted. She could hear him even though her windows were rolled up.

That’s when she told police he pulled out a semi-automatic pistol and pointed it at her, crossing his right hand over his left hand that gripped the steering wheel.

She couldn’t move. There was too much traffic.

He pulled the trigger and a shot rang out in her direction, she told police, adding he fired again before speeding off. She and her car weren’t hit.

She got onto the highway and took the first exit onto William Cannon Drive. She could still see the truck, and followed, reading the license plate off to the 9-1-1 dispatcher, who told her to stop following him.

Police tracked down the license plate and arrested Lopez. As of Thursday, he is in custody in the Travis County Jail and is charged with aggravated assault with a deadly weapon and deadly conduct – discharge firearm at an individual. His bond was set at $75,000 for the two charges.
