DALLAS (CBSDFW.COM) – A nurse carjacked in a Parkland Hospital parking lot is furious after she says police let the men who robbed her go free.

“They caught men who robbed me and totaled my car and didn’t do anything,” claimed Mary Ball.

Ball said she had just parked in the employee lot the afternoon of April 7, when three men approached her. “And one of them pulled a gun out and said, ‘This is a hold up. Give me all your stuff’,” she said.

According to Ball, the men stole her bag, watch, and car.“I was shocked,” she said. “I literally stood there and watched them drive away.”

The Dallas Police Department confirms officers found Ball’s car, with three people inside, about six hours after she was held at gunpoint. The department says the driver of the car crashed into an electric pole at the intersection of East Camp Wisdom Road and University Hills Boulevard and left the scene.

Officers investigated the crash but say since the carjacking took place on hospital property the responsibility to investigate that crime falls under the jurisdiction of a different agency — the Dallas County Hospital District Police Department.

A Dallas police spokesperson initially said officers had reached out to the hospital police to notify them they’d found the car and detained two male passengers, but later clarified it’s not clear when the department made contact.

Ball said she did receive a phone call from a Hospital District detective alerting her to the discovery of two likely suspects, a gun, and her car at the scene of a crash. She said the detective told her Dallas police would be calling. “Never got the phone call,” she said.

The next day Ball learned Dallas police had released the men. “For some reason, they didn’t arrest them and let them go.”

Dallas police say, since neither men were driving Ball’s car they couldn’t be held as suspects in the crash and referred CBS 11 News to the Hospital District police for information on its investigation.

Parkland Health & Hospital System spokesperson Mike Malaise said in a statement, “There is an open investigation… The Dallas County Hospital District Police Department is collaborating with (the Dallas Police Department) in this matter. We have no additional information at this time.”

Ball, meanwhile, says she continues to pay the price. “Personally, I’m in hell if I’m being honest. I’m off from work on stress leave, too scared to go back to a job I love.”
