Three men were killed in what appear to be unrelated shootings in the District late Friday and early yesterday, police said.

Police said they have made no arrests in the slayings, which pushed the number of homicides in the city to 152 for the year.

The first shooting occurred about 11:50 p.m. Friday in Northeast Washington. Officers heard gunshots in the neighborhood and went to the 300 block of 50th Street NE, where they found Miguel Henry, 20, lying on the ground, police said.

Henry, of the 5000 block of Banks Place NE, had been shot several times in the head and body, police said.

He was taken to Howard University Hospital, where he was pronounced dead about 30 minutes later.

Authorities said Henry had been wanted on an arrest warrant charging him with a carjacking in Maryland.

Detectives did not know whether that case was connected to his death, investigators said.

The next shooting occurred about 1:45 a.m. in the 600 block of Irving Street NW.

James Fletcher, 23, was discovered in front of his house with wounds to his body. He was taken to Washington Hospital Center, where he died.

Police said the shooting appeared to be connected to an unspecified dispute.

Ten minutes later, a 38-year-old Severn man was killed in a double shooting in an alley about four miles away in Northeast Washington, police said.

James Michael Campbell was found shot in the head in the alley behind the 1600 block of E Street NE. Another man, whom police declined to identify because they consider him to be a witness, was hospitalized for a gunshot wound to the leg.

Police said they believe two guns were used in the E Street shootings but released no further details about the incident.

The homicides were among five killings in two days in the District. The city remains on pace to record about as many homicides as last year, when 198 people were killed. If the trend continued, it would be the first time in two decades that the city recorded fewer than 200 in each of two consecutive years.

Police said they also were investigating a shooting Friday night that wounded a 37-year-old man in the throat. The man, whom they declined to identify because they said he was a witness, was shot about 10 p.m. Friday at Ninth and P streets NW, police said.

The man was hospitalized in serious condition with what police said were not life-threatening wounds.

Authorities urged anyone with information about the killings to call them at 202-727-9099. Police offer rewards of up to $25,000 for information in homicides.
