ROCK HILL — Police have arrested another suspect in an armed robbery this month in Rock Hill--one that occurred during a soured drug deal and not at a gas station, as victims told police.

Tyler Mitchell Fesperman, 17, of Rock Hill is being held at Moss Justice Center in York on bond. He is charged with armed robbery and criminal conspiracy in connection with the crime, according to a York County Sheriff’s report.

Keion Henreik King, and Kendricko Dayshaun Young, both 17, were arrested within days of the incident. Kourtney Alvis, 20, turned herself in about a week later, according to a sheriff’s report. The three have bonded out.

The victims, two 20-year-old men, initially told police they were pumping gas at a gas station when the four suspects pulled up in a car and two got out and held them at gunpoint and demanded they empty their pockets, according to the report.

But an investigation showed the events unfolded in the parking lot of the Catawba Baptist Church, located at 2639 Catawba Church Road in Rock Hill, the report says.

The suspects met the victims there to buy marijuana, said York County Sheriff's Detective Ralph Gurganus.

The deal went sour after King and Young got out of the car, took the drugs from the victims, and Young pulled out a handgun and demanded they empty their pockets, Gurganus said. When the victims showed that they had nothing, the suspects drove off.
