De’mari Twyman, 21, was shot and killed on the 700 block of Monroe Street NE in Washington, D.C., near Catholic University on the morning of February 28, 2020. Police say the shooting occurred at about 8:52 a.m.; first responders found Twyman with multiple gunshot wounds and he died after being taken to a nearby hospital. The Metropolitan Police Department opened a homicide investigation and later identified 22-year-old D’Andre Mickle of Northwest D.C. as the person believed responsible for the fatal shooting.

Police say Mickle was involved in a separate incident on April 28, 2020, in the 1800 block of 24th Street NE, during which he was shot and killed after forcibly entering a residence and being confronted by an armed individual; that death was later classified as a justifiable homicide. No one has been publicly identified as charged in Twyman’s killing in this account.

If anyone saw the February 28 shooting or has information about De’mari Twyman that could help, please come forward.
