During seven of the eight robberies, two suspects went into the convenience stores — all but one of which were 7-Elevens — and took cigarettes and lottery tickets, police said. In one robbery, only one suspect went inside and did not take lottery tickets. Shortly after several of the robberies, the tickets were cashed or attempted to be cashed at a Landover gas station.

Police used fingerprints on one of the cashed lottery tickets to identify McKinnon. After the final robbery on January 30, police followed McKinnon, Harried and Crenshaw to the Landover gas station and arrested them. Singletary was arrested on Tuesday, police said.

The robberies occurred between January 12 and January 30 at a gas station and convenience stores in Kensington, Rockville, Gaithersburg and Silver Spring.
