On May 18, 2023, 18-year-old Tenneson Vaughn Leslie Jr. of Greenbelt was fatally shot at Wheaton Metro Station after a confrontation between two groups of young men escalated on an escalator. Surveillance video shows the dispute turned physical, and as Leslie and his friends tried to flee, a 16-year-old who was later identified as Emmanuel Leonard Simmonds produced a firearm and fired, striking Leslie in the back of the head.

Montgomery County Police found Leslie unresponsive near the bottom of the escalator; he was taken to a hospital where he died. Officers arrested Emmanuel Simmonds at his home on May 24, 2023; he was charged as an adult with second-degree murder, first-degree assault, reckless endangerment, and firearm offenses. A 14-year-old male was also arrested and charged as a juvenile with being an accessory after the fact.
