The manager of a taxi repair shop in Southwest Washington who was killed during a robbery last year had chased the assailant after handing over money, according to court documents.

Video from a security camera shows a man walking into Gold Star Cab, at Q and South Capitol streets, a block from Nationals Park, about 7 p.m. July 19, according to documents filed in D.C. Superior Court.

The video shows the man running out, the documents say, followed by the victim, Hayes Osei Dennis, 60, who came from Ghana a decade ago and lived with his wife and seven children in Fort Washington.

“The suspect appears to stop, turn and the decedent collides into the suspect,” the court documents say. “This is the moment it appears that the suspect stabbed the decedent.”

The suspect, Darryl Matthews, 29, of Southwest, was charged with second-degree murder while armed, and on Wednesday, he was ordered held until a preliminary hearing April 26.

Dennis was closing the shop to head home to dinner with his wife and a visiting brother-in-law, who was scheduled to fly to Ghana the next day.

The charging documents state that a man walked into the repair shop with a knife wrapped in a black shirt or jacket, got a cup of water and then threatened Dennis. He said, “Give me your money, or I’ll kill you,” a witness told police. The store manager said last summer that Dennis had given the man $20.

After the holdup, authorities said, the man left the shop, and Dennis followed. The court papers say an informant who watched the video identified Matthews, as did a caller to a police tip line.

Police also said Global Positioning System data indicate that a cellphone used by the suspect was “in close proximity to the scene of the stabbing death.”
