At a candlelight vigil against gun violence Sunday night, D.C. Mayor Vincent Gray spoke about the “tragic” and “incredibly disquieting” circumstances of the District’s third homicide of the year.

“One person killed another, in a gun battle,” Gray described in a video shot at the vigil, which was held at Shiloh Baptist Church. “There were casings all over the street.”

David Lee Robinson, 19, of Northwest Washington, was shot in the 5700 block of Foote Street NE about 2:30 a.m. Sunday morning, police said. He was pronounced dead at Howard University Hospital about 3 a.m.

Police do not have a suspect in custody or a motive in the case, but Gray said the shooting resulted from a robbery because Robinson’s sneakers were missing.

“He was being robbed for his Nike tennis shoes,” Gray said. “A life for a pair of Nike tennis shoes.”

Robinson’s death is the District’s third homicide of the year. Police said the death of 56-year-old Leroy Studevant of Washington was classified as the first homicide of 2012, followed by 21-year-old Howard Ricardo Sampler.

The Metropolitan Police Department offers a reward of up to $25,000 to anyone who provides information that leads to the arrest and conviction of a person wanted for any homicide committed in the District.

Anonymous information also may be submitted to D.C. Crime Solvers at 1-800-673-2777 or by texting a message to 50411. A reward of as much as $1,000 may be given if a caller’s information leads to an arrest and indictment.
