Man Sentenced to 50 Years for First-Degree Murder in 2014 Christmas Eve Killing of Waitress
WASHINGTON –Marvin Lopez, 45, of El Salvador, was sentenced to 50 years in prison for the 2014 Christmas Eve murder of his ex-girlfriend, Evelyn Yamileth Arroyo Guerra, announced U.S. Attorney Matthew M. Graves and Chief Pamela Smith of the Metropolitan Police Department (MPD).
On October 25, 2024, Superior Court Judge Michael O’Keefe sentenced Lopez to the prison sentence for first degree murder while armed and a seven-year prison term for possession of a firearm during a crime of violence to be run concurrently.
According to the government’s evidence presented during an eight-day trial in November 2023, a pair of MPD Lieutenants were driving south on 14th Street on Dec. 24, 2014 when they heard two gunshots. Citizens on the 3900 block of 14th Street pointed in the direction the gunman had run. One of the Lieutenants gave chase on foot but lost the shooter in a wooded area at the end of Shepherd St, NW. The other Lieutenant found Yamileth on the sidewalk in front of the restaurant at 3910 14th Street NW, suffering from a gunshot wound to her chest and a graze wound to her head. Yamileth had been shot as she was arriving for work, as a waitress, at El Sabor Latino.
Two witnesses who knew Yamileth told police that they had seen Lopez—the victim’s recent ex—approaching her outside of the restaurant moments before the killing. One of the witnesses showed police Facebook messages between Lopez and Yamileth from days before the murder in which he threatened to kill her. Although an arrest warrant was obtained the next day, Lopez was not located by police before he fled to El Salvador. He was extradited back to the United States and arrested in March of 2023.
In announcing the sentence, U.S. Attorney Graves and Chief Smith commended the work of those who investigated the case from the Metropolitan Police Department. They acknowledged the efforts of those who worked on the case from the U.S. Attorney’s Office, including Supervisory Paralegal Specialist Tasha Harris; Investigative Analyst Zachary McMenamin; Victim/Witness Advocates Karina Hernandez; Maenylie Watson, Tonya Jones, and Katina Adams-Washington, of the Victim/Witness Assistance Unit; Supervisory Litigation Technology Specialist Leif Hickling and Paralegal Specialists Grazy Rivera, April Urbanowski and Maria Sanchez.
Finally, they commended the work of Assistant U.S. Attorney Christian Natiello who investigated and indicted the case and Assistant U.S. Attorneys Kristian Hinson and Sarah Prins who prosecuted the case.
