Police have identified a 13-year-old boy who was shot and killed on Sunday in what investigators believe was a dispute among young people in Shaw.

Malachi Lukes was shot at around 2 p.m. on Sunday in the 600 block of S Street NW, according to the Metropolitan Police Department. Officers responded to a call about the sound of gunshots and found Lukes in an alley, unconscious and suffering from a gunshot wound. He was taken to the hospital, where he was pronounced dead after lifesaving efforts failed, per police.

A second juvenile was also found nearby, on the 600 block of Rhode Island Avenue NW, suffering from a gunshot wound to the leg. He was taken to the hospital in stable condition.

MPD Police Chief Peter Newsham told reporters that the shooting did not appear to be random. “There was some kind of a dispute out here involving these young people,” he said. “We don’t know what it was yet but it doesn’t feel like an unintended target.”

Lukes was just days from his fourteenth birthday, according to the Washington Post, and he attended middle school at Cardozo Education Campus. Lukes was one of two young teenagers handcuffed at the U Street Metro stop in June, prompting a confrontation between Metro police officers and a bystander who questioned their tactics in detaining the adolescent boys. His mother, Melissa Laws, told the Post that the interaction had profoundly affected her son.

“The incident kind of broke him. . . . It made him really closed. He lost all respect for authority, to the point where you really couldn’t touch him,” she told the outlet.

In January, D.C. police changed its policy to stop handcuffing suspects age 12 and under in most cases, but the Metro police do not have a similar policy in place.

Lukes gave a TV interview last year about his interaction with the police that day, and participated in a play called the Wizard of Shaw about go-go music and gentrification in Shaw, the Post reports. His mother, Laws, is a program director at the Shaw Community Center, where she helps at risk youth, per the outlet.

“He was just a normal teenage boy,” Laws told the Post. “He lived, and he had the same struggles, the same issues, as all the other children growing up around here.” She said that she wanted her son’s death “to be a wake-up call.”

Detectives did not recover a gun at the scene, according to Newsham. MPD is offering a $25,000 reward for anyone who can provide information about the shootings that leads to an  arrest and conviction.

The teenage boys were shot on a particularly violent day in what has been a violent year in the District of Columbia. Just after 2 p.m. on Sunday, at nearly the same time as the Shaw shooting, an adult male was shot and killed on the 4900 block of Nash Street NE, according to police. Authorities have not yet released his name, pending the notification of his family.

Around 7 p.m. on the same day, three more adult men were injured in a shooting in Northeast.

Two men were shot inside a car traveling up the westbound lanes of the 100 block of New York Avenue, according to NBC Washington. They were found near the Wendy’s at the intersection of Florida Avenue and New York Avenue NE. A third man was found shot on Florida Ave NE, and police believe they were all injured in the same shooting, per the outlet. Two of the men are stable, while the third is in critical condition, police told reporters.

And just before midnight on Sunday, another shooting occurred on the 4400 block of Benning Road, though no one was injured, according to MPD.

There have been 28 homicides in D.C. so far this year, one fewer than this time in 2019. Last year was the District’s deadliest year on record since 2008.

“Violent crime across our city has dropped dramatically,” Newsham told reporters on Sunday. “The one persistent issue we have is this gun problem.”

This story has been updated to clarify that one of the shootings occurred on Nash Street NE, not Nash Street NW.
