Tyrone Slay Jr. was 31 when he was fatally shot in Baltimore on March 31, 2011. He was an African-American man whose death came during a year of elevated violence in the city.

Investigators struggled to develop the case amid limited witness cooperation and insufficient evidence, and no arrests or publicly announced identifications of suspects have been made. The case went cold as time passed and remains unsolved.

Does anyone who knew Tyrone or who was in those neighborhoods that night have information that could help bring clarity to what happened?
