Christopher Rowe

Christopher Rowe is accused of shooting Christopher Corder, 27, in the head and killing him over an ounce of marijuana, the Dallas Morning News reported. Corder was taken to Medical City Dallas Hospital around 1 a.m. Sunday. The Dallas police were notified and began an investigation.

A witness told police he took Corder to the Summer Glen Apartments, at 9624 Rolling Rock Lane, around midnight to sell an ounce of marijuana to a buyer (allegedly Rowe) who Corder described as a new customer.

When they arrived, Rowe allegedly got into the back seat of the witness’ vehicle, pulled out a pistol and told the pair to “give me all your (expletive),” the Morning News reported. The witness heard a gun shot, grabbed a pistol of his own and said he fired at Rowe as he ran through the parking lot.

Corder was unresponsive when the witness returned to his vehicle.

Rowe is being held in custody at the Dallas County jail with bond set at $500,000.
