On the evening of October 24, 2018, 22-year-old Roger Tom Marmet was driving his Jeep Liberty in the 1200 block of 17th Street NE when a stray bullet pierced his vehicle. Marmet, a recent University of Vermont graduate who had been volunteering with So Others Might Eat in Washington, D.C., was struck while stopped at a traffic light around 6 p.m. First responders, alerted by a gunfire detection system, found him unconscious; he was taken to a nearby hospital and pronounced dead shortly after arrival.

Investigators determined Marmet was not the intended target. According to the investigation, the shooter fired across a busy intersection at another person and Marmet was an innocent victim caught in the crossfire. The Metropolitan Police Department arrested 22-year-old Barry Marable of Northeast D.C. on December 28, 2018; Marable was charged with first-degree murder while armed.
