Tyrone McMillan, a 30-year-old African-American man, was fatally shot on April 9, 2017, in Baltimore. His death was one of 343 homicides recorded in the city that year during a wave of violence that overwhelmed many neighborhoods.

Details about the shooting and the events leading up to it are sparse. Investigations from that period were often hampered by a lack of cooperating witnesses, and there have been no publicly announced arrests or identified suspects in McMillan’s case.
