On the evening of November 15, 2011, 31-year-old Marvin Tomlinson was near a playground at an apartment complex on County Road in District Heights, Maryland, when a minivan pulled up and a group of young men got out and began a robbery. Tomlinson was with four teenage boys; as the assailants started pistol-whipping him, he told the teens to run. The boys escaped, but Tomlinson was shot and died from gunshot wounds. His body was found shortly after 9:30 p.m.

Detectives quickly identified four suspects. Within days and weeks authorities arrested Trevon M. Montgomery, 17, on November 17; Ronald J. Minor, 17, who surrendered eight days later; 20-year-old Dominic C. Givens, arrested in Raleigh, North Carolina, on December 9; and 18-year-old Dajaun J. Brooks, taken into custody the following week. All four were charged with first-degree murder. Dominic Givens was later convicted of first-degree murder for his role in the robbery and fatal shooting.

Are there details about that night or the people present that could help clarify what happened?
