FORT WORTH (CBSDFW.COM) – Fort Worth police are investigating a shooting that left one person dead in a parking lot Sunday.

Police say officers responded to the shooting just before 5 p.m. Sunday at Eastchase Parkway and Meadowbrook Boulevard.

According to police, two males were walking through the parking lot when one of them pulled a gun and shot the other. The shooter then jumped into a U-Haul truck and fled the scene.

The victim was transported to a hospital where he was pronounced dead.

Police are still investigating what led up to the shooting.

One witness says she saw a gun next to the victim. She also called 911 and tried to save the victim.

“I was the first one to call 911. The first one to walk over there to him… to see that baby gasping for breath… trying to breathe,” said the female witness. “When I looked again, I saw the boy staggering. He got up, he fell down, and that’s when he just fell onto his back.”
