Marcus Walker, 24, Sentenced to 30 Years for Killing Ex's New Boyfriend

WASHINGTON – Marcus Walker, 24, of Washington, D.C., was sentenced today to 30 years in prison, by Superior Court Judge Robert Okun in the shooting death of Erik King on October 11, 2022, in Northeast Washington, D.C., announced U.S. Attorney Matthew M. Graves and Chief Pamela Smith, of the Metropolitan Police Department (MPD).

            Walker was found guilty by a Superior Court jury on May 7, 2024, of second-degree murder while armed, two counts of assault with a dangerous weapon, as well as second degree cruelty to children, three counts of possession of a firearm during a crime of violence, and possession of a large capacity ammunition feeding device.

            In addition to the prison term, Judge Okun ordered Walker to serve five years of supervised release.

            According to the government’s evidence, Walker was living in the living room of his ex-girlfriend’s apartment. On October 11, 2022, the defendant became upset that his ex-girlfriend and her new boyfriend, Erik King, were engaged in sexual relations in the bedroom of the apartment. After sending his ex-girlfriend aggressive text messages for approximately an hour, Walker burst into the locked bedroom door and told the two to stop having sex. When the couple ignored his demands, the defendant shot Mr. King twice in the chest and scrotum area. Mr. King died on scene. A six-year-old child was also present in the bedroom when the shots were fired.
