A Denton man was arrested Thursday morning on an attempted murder charge after police said he hit an 18-year-old man with a vehicle during a drug deal in Corinth.
David Marcus Katlin, 20, was booked into Denton County Jail. The victim, who police have not identified, was in critical condition but slowly stabilizing on Thursday afternoon at Medical City Denton, according to Corinth police Chief Debra Walthall.
Corinth police said they responded to a robbery report at 11:29 p.m. Wednesday at the Kensington Park Apartments, 3150 S. Garrison Road.
Responding officers found the victim lying unconscious near a driveway.
After officers spoke with witnesses and gathered evidence, police determined Katlin and the victim "engaged in an illegal narcotics transaction," Corinth police said in a press release. The victim ran away with the driver's money without delivering the drugs when Katlin struck him, the release said.
Corinth police Assistant Chief Greg Wilkerson said investigators have not tested the drugs, but they believe the substance is crack cocaine. Wilkerson said additional charges could be filed against the victim and two other people involved in the transaction.
"I would consider it still an ongoing investigation," he said.
Katlin fled the scene in a dark-colored, four-door Pontiac, the release said. Police recovered the vehicle in Valley View and later arrested Katlin in Denton. Walthall did not know specifically where Katlin had been found in the city.
Katlin's charge is a second-degree felony and punishable by up to 20 years in state prison.
