ROCKVILLE, MD — Thanks to a photograph posted by Montgomery County Police, an anonymous tipster was able to help identify a suspect in the Oct. 2 armed robbery of Dawson's Market in Rockville. The person who submitted the tip is eligible for a reward of up to $10,000, according to police.

Based on the anonymous tip, police arrested 43-year-old Devin Byron Dorsey in Germantown on Oct. 14, in connection with the robbery.

After transporting Dorsey to Montgomery County Central Processing Unit, police charged him with armed robbery, robbery, second-degree assault and theft of less than $100. He was then held without bond.
