Mark Tyrone Nicholson, 51, was shot multiple times and killed outside his home in the 3400 block of Liberty Heights Avenue in Baltimore on April 17, 2015. Neighbors described the shooting as very surprising and eerie, and it left the community shaken.

Nicholson worked full time while running his own business. He was a father of two and a grandfather of two who enjoyed fishing and was remembered by family as a loving man. Despite appeals for information and a reward of up to $4,000 for information leading to an arrest and indictment, the case remains unsolved and no suspects or arrests have been publicly announced.

Does anyone who lived near Liberty Heights Avenue in April 2015 or who knew Mark have information that could help bring his killer to justice?
