Simeon Mbuyu Mukuna was 18 and a senior at Richard Montgomery High School when he was shot and killed in a Columbia, Maryland parking lot on the evening of February 6, 2021. He had been helping a friend with car maintenance at the Monarch Mills apartment complex and was walking to his car to get a jacket when a vehicle pulled up beside him and its driver opened fire. Mukuna was struck multiple times and was pronounced dead at the scene; no weapon was found on or near him and witnesses did not see him with one.

The shooter, 23-year-old Shawndel Arnez Weems, had no known prior connection to Mukuna, later told investigators he believed Mukuna was looking at him with malice and thought he might be armed, and initially barricaded himself in his apartment before surrendering. Weems was arrested and charged in the case. Mukuna is remembered for his magnetic smile and his passion for soccer; his family described their immeasurable pain at what they called a senseless loss.

If anyone was in the Monarch Mills parking lot that evening or has information about what preceded the shooting, please come forward.
