Eight people were killed in the District in a bloody weekend of stabbings and shootings that pushed this year's homicide total to 225, police said. The total was 214 at the same time last year.

The most recent deaths occurred about 3:45 yesterday morning when a man and woman were shot near Dunbar High School in Northwest Washington.

Police said the man was shot in the chest and apparently robbed of his car in the 1300 block of New Jersey Avenue NW. The attackers sped off in the car, but returned a few minutes later to nearby 5th and N streets NW and shot the woman, officers said. Police said they have no motive in the shootings, and the names of the dead were not released.

Most of the bloodshed occurred Saturday, beginning with the 2:30 a.m. shooting death of Michael Harvey, 24, of the 700 block of Kennedy Street NW, who police said was found in an alley near the 700 block of Taylor Street NW. Authorities said they had neither a suspect nor a motive in the case.

About noon Saturday, police said, a woman identified as Diane Weaver, 38, of the 4900 block of Blaine St. SE, shot and wounded her father in an argument, then fatally shot herself. The man, whose name was not released, was taken to D.C. General Hospital with a wound to his abdomen. His condition could not be learned.

At 3:45 p.m. Saturday, Kevin McNair, 29, of the 4000 block of E Street SE, was found suffering from a gunshot wound in the 5100 block of Nannie Helen Burroughs Avenue SE. He died at the scene.

About a half-hour later, an unidentified man was found shot to death in the 4400 block of Deane Avenue NE.

There was a nonfatal shooting as well on Saturday.

A youth was shot by a District police officer about 3 p.m. in the 4900 block of East Capitol Street.

Police said an off-duty officer, Bruce Faison, saw a youth pull a shotgun out of his pants during an argument. When Faison yelled for him to drop the gun, the youth, whose name was not released, turned the gun on Faison, police said. Faison shot the youth in his chest.

The youth, who was charged with assaulting a police officer, was listed in good condition at D.C. General Hospital.

Two people died in stabbings that occurred on Friday. About 8 p.m., Michael Tuck, 35, was found suffering from a stab wound in the 1200 block of I Street SE. He died early Saturday at Hadley Hospital.

Another man, Russell Savoy, 26, of the 200 block of Ellerby Drive, Indian Head, was stabbed Friday in the unit block of Galveston SW. He was pronounced dead at 5:30 a.m. Saturday at Hadley Hospital.
