Those 28 deaths are on track with last year’s pace; the city saw 29 homicides by the same time in 2015, police said.

The four most recent killings included two in Northeast D.C., one in Southeast, and one in Northwest. An arrest has been made in two of the cases, and suspects are still sought in the others.

One case dates back to last year, when Medina Michelle Thornton, 43, was found unconscious by a neighbor in her apartment in the 300 block of Delafield Place Northwest on September 19, 2015.  Thornton died April 3, placing her death among this year’s statistics; she suffered blunt force trauma to the head, according to the Office of the Chief Medical Examiner. No arrests have been made in the case.

Gabriel Carlos Turner, 43, was fatally shot on March 24 in the 2600 block of Birney Place Southeast as he left his mother’s apartment en route to a bus stop. Neighbors claimed they heard six shots; Turner worked 15 years in janitorial services for the FBI, according to Washington, D.C. NBC affiliate WRC-TV. Police have not released any information regarding a suspect or motive in the incident.

“I don’t know why somebody had to kill him,” Turner’s mother, Ellen Turner, told the station.

Detectives are searching for a suspect they have identified in connection with the March 16 shooting death of Darnell Lee Richardson, 29, of Cheverly, Md. Richardson’s body was found in the 3400 block of Benning Road Northeast. The suspect charged with the first degree murder while armed for Richardson’s death is Leon Stewart, 24, of Northeast D.C. Stewart is described as a Black male, five-feet, seven-inches tall, weighing 190 pounds.

On March 26, Davonte Washington was sitting on a Deanwood Metro platform bench with his mother and two sisters, on his way to get a haircut for Easter when, according to the Post, he became involved in an argument with another teen. The other youth produced a gun and fatally shot Washington.

Maurice Bellamy, 17, of Southeast D.C., was arrested and charged as an adult with first degree murder while armed in connection with the Metro murder of Washington. According to the Post, when Bellamy appeared for his hearing on Mar. 29, Washington’s mother shouted in the courtroom, “That’s the one who killed my baby!” and began sobbing. Washington’s life and legacy was honored in a vigil on Mar. 30 and at his funeral on Apr. 8.
