ARLINGTON (CBS 11 NEWS)An Arlington Independent School District teaching assistant is shaken, after police say a man shot into her minivan in an apparent case of road rage.

Margaret Stamp went to Walmart around 6:30 Wednesday morning to pick up some cough syrup. As she pulled out of the parking lot, Stamp says a man driving a white car drove up to her and repeatedly flashed his lights.

“The white car was right on my tail end, like I knew him. Like, pull over, pull over,” she recalled.

Stamps’ instincts told her something wasn’t right. She says dialed 911 and followed the driver into a nearby neighborhood, so she could get a street number on the location to provide to the 911 operator.

As she was on the phone with the police dispatcher, Stamp says the driver got out of his car, ducked, and then began firing at her.

“I was just hysterical, screaming, ‘They shot at me. They shot at me. I can’t believe they shot at me.’”

Stamp said she threw her van in reverse and backed out, hoping she wouldn’t hit anything as she tried to escape. She was able to drive down the block. She says the shooter drove away in another direction.

As she sat shaking in her van, a neighbor ran up and put the vehicle in park for her.

Stamp counted 11 gunshots. One bullet shattered the back window of her vehicle. “It is a good thing I turned when I did. Had I not, where he shot it would have gone through the window and would have hit me,” she said.

Later in the morning Arlington police arrested a man on an unrelated charge. Investigators say the man is now the suspect in this incident and will be charged for the shooting.

Stamp says she can’t stop thinking about what might have happened.

Stamp is a teaching assistant at Webb Elementary School in Arlington. On many mornings, she uses her van to pick up kids in the neighborhood whose parents do not have a car.

The back of the van, where the glass was shot out, is usually loaded down with book bags and students’ wheelchairs.

“I work with children. How could [someone] be shooting? He was just aimlessly shooting wherever he was driving with no regard for human life.”
