Police have charged a man after he allegedly beat his girlfriend and threatened to kill her with a gun while driving along the interstate in Austin.

According to the affidavit released by the Austin Police Department, the couple of six years were driving home from a concert in Cedar Park. They were arguing in the vehicle, and when the two reached Downtown, police said Carl Burford began punching her "approximately thirty times" in the head, face, shoulder, arm, leg and lower back.

The alleged victim then told police that he said to her he should "just kill her now." He removed a black handgun from the center console of the truck. The victim said she knew the gun was real because she has seen him fire it in the past.

The man allegedly told her he was going to kill her, then drive to her mother's home and murder her along with their two children. He then allegedly told her he was going to murder any law enforcement officers he encountered and commit suicide.

The victim told police she jumped from the moving truck as it neared the 6th Street exit of Interstate 35.

A witness called 911 after seeing her jump at around 11:39 p.m. When officers interviewed her, she had bruises on her body.

Burford has been booked in the Travis County Jail with a bond set at $100,000.
