Police: Pizza-car thief attacked with hammer

Dwayne Guidry

AUSTIN (KXAN) — Police say Dwayne Guidry, 25, died shortly after stealing a car that was left running outside of a South Austin Domino’s Pizza on Monday night. Authorities say customer Joseph Mobley, 32, was picking up a pizza when he saw Guidry stealing the car and chased him down — first in his car and then by foot  — and hit Guidry on the back of the head with a hammer. However, Guidry ultimately died due to asphyxiation after Mobley “choked him out,” police say.

Police say they arrived in the 10200 block of Manchaca Road to find Mobley standing over Guidry, who was lying facedown on the ground. As EMS crews got there and began to work on the unresponsive Guidry, police say Mobley told them he had “hit him with a hammer” and “choked him out.” Mobley also ran through the details about what led up to the death, police say.

Mobley says it started at the Domino’s Pizza at 1807 West Slaughter Lane, where Guidry got into a pizza-delivery driver’s silver Ford Mustang. It’s engine had been left running in the parking lot outside Domino’s. Mobley told police he knew it didn’t belong to Guidry, and an employee also reportedly ran out and yelled that his car was being taken. When Guidry drove off with the Mustang, Mobley says he decided to follow him — even with his wife and son in the car.

Mobley followed Guidry into a neighborhood at Manchaca Road and Redwater Drive, which is where police were initially dispatched to at 9:08 p.m. Mobley’s wife told police that her husband was familiar with the neighborhood and blocked Guidry from leaving, but Guidry hit their car with the Mustang as he tried to get away. That’s when Mobley reportedly got out of his car, and Guidry crawled out of the driver’s-side window. Mobley told police Guidry took off running.

“That’s kind of when I lost my [expletive] and chased him down,” Mobley said, according to court documents.

Mobley allegedly hit Guidry in the back of the head with a hammer, and Guidry fought back, managing to knock the hammer out of Mobley’s hand. Mobley told police he then got Guidry to the ground and then “choked him out” using his arm and elbow — a form which Mobley allegedly told police was “the right way.” Mobley told police he stayed on top of Guidry because he was taught that “when they wake up they will attack you.” Mobley’s wife told police she had gotten in the driver’s seat of their car and driven to look for Mobley, finding him over Guidry and holding Guidry’s hands behind his back.

EMS crews took Guidry to University Medical Center Brackenridge, where he died at 9:50 p.m. Mobley went to the hospital as well, for swelling in his left hand, but he had not other apparent physical injuries and was later released from the hospital.

“We would have asked that Mr. Mobley would have called us,” said APD Sgt. Brian Miller on Wednesday. “He did a good job following him through the neighborhood … but from there on out, let the on-duty officers take care of it.”

Police managed to find the hammer used in the attack near where they caught up with Mobley and Guidry. Mobley’s wife also told police that — during the car chase with Guidry — he had asked one of his son’s to pass him the hammer from the backseat.

Mobley is currently being held in the Travis County Jail on a second-degree felony manslaughter charge. His bond is set at $60,000. This is the city’s 17th homicide.

The Travis County Medical Examiner’s Office conducted an autopsy on Tuesday and labeled Guidry’s death a homicide due to asphyxiation. They also found two injuries on the back of his head. After consulting with the Travis County District Attorney’s Office, police say they are pursuing manslaughter charges.

The investigation into this case continues, and anyone with information about the incident is asked to call the Homicide Tip Line at 512-477-3588 or Crime Stoppers at 512-472-TIPS or text “Tip 103” + your message to CRIMES.
