Two men were shot to death Saturday in the District, closing an unusually deadly week on the city’s streets.

Just before 4 a.m. Saturday, police found Domingo Ezirike, 40, suffering from a fatal gunshot wound near the entrance to the Kenilworth Aquatic Gardens in far Northeast Washington. Ezirike, of Lanham, was found in the taxi he drove in Prince George’s County.

Shortly after 10 p.m. Saturday, Keenan Jerel Lee, 20, was fatally shot on Georgia Avenue NW near W Street. Lee, of Capitol Heights, was involved in an altercation on the street before the shooting, said D.C. Council member Jim Graham (D-Ward 1) and a law enforcement source.

The dispute arose between Lee and another individual over a “girl-related problem,” Graham said. Witnesses said Lee struck the shooter before he was shot, the source indicated.

“The guy just pulled a gun,” Graham said. “You gotta be careful who you punch. You don’t know who’s got a gun in their pocket.”

The shooting happened near the campus of Howard University, which celebrated its homecoming over the weekend with a Saturday afternoon football game and an elaborate series of other events. Police blocked off streets around the campus, including Georgia Avenue, for festivities that attracted students and alumni as well as people not affiliated with the university.

A university spokeswoman said that no Howard students or personnel were involved in the shooting. Police have not identified a suspect.

Lee’s killing was the city’s eighth homicide since late on the previous Saturday, when Davon Paul Gray, 21, was slain in the 2500 block of High Street SE in Anacostia. During the past week, Gray and six others were shot to death; one man was fatally stabbed.

Another man was found dead with stab wounds Thursday in the Barry Farm area, but the cause of death is under review and a suspect in the killing has not been charged with murder.

Police have identified suspects in four of the homicides, including Ezirike’s. On Sunday, police arrested Rashad T. Slye, a 20-year-old Southeast Washington resident, and charged him with first-degree murder, according to a police news release.

Lee’s death brings the city’s homicide total to 95 this year — fewer than the 106 slayings the city had seen at this time last year. By the end of 2010, 132 were killed in the District. But the week’s pace of violence is the most intense in any area jurisdiction since January, when 12 people were slain in Prince George’s County in the first 11 days of the year. Eighty-seven people have been killed in Prince George’s this year.
