Grand Prairie police said they arrested a store employee they suspect of killing someone who reportedly stole from the business where he works.

Per The Dallas Morning News, police say Price Mackey was arrested on Wednesday and now faces a murder charge for allegedly shooting 22-year-old Dorian Medina.

Grand Prairie police say that officers responded to the 700 block of West Jefferson Street, near Southwest Sixth Street, after receiving a call at about 2:30 p.m. alerting them to the location.

Upon arrival, officers found Medina in his car with a gunshot wound. Police say he was already dead by the time first responders arrived.

According to The Dallas Morning News, police said that Mackey allegedly shot Medina as he was driving away after stealing from the pawnshop. Mackey is one of the store’s employees.

Criminal defense attorney Anthony Farmer ruled out the possibility of the killing as a self-defense case or castle doctrine situation, according to a news report by FOX 4 News.

“If somebody is running away after stealing a small item out of a store, the threat is not reasonable. And I think you have a case of murder based upon what I’ve heard,” Farmer said.

According to FOX 4 News, Farmer said that the use of deadly force would only be applicable if the person involved genuinely felt their life was at risk. It would have been a different story if the person stealing had brandished and/or pointed a weapon.

Mackey is being held at the Grand Prairie Detention Center with his bond set at $100,000.
