Matthew Shlonsky, 23, a recent graduate of American University and consultant at Deloitte, was killed on August 15, 2015, in Washington, D.C. Just before 5 p.m. he and friends had exited an Uber near the Shaw-Howard University Metro station en route to a going-away party when a shootout broke out nearby on the 1800 block of Seventh Street NW. Shlonsky was an innocent bystander struck in the chest; officers were flagged down by a witness and he was taken to a hospital where he died.

The investigation identified and led to the arrest of three men in connection with the shooting. Marcus King, 19 at the time, turned himself in on August 21, 2015, and was charged with second-degree murder while armed; Andre Dudley and Christopher Proctor were later arrested. In June 2018 Dudley, King and Proctor pleaded guilty to charges related to Shlonsky’s death and in August 2018 each received prison sentences.

Did anyone who knew Matthew in D.C. or who was in that area that evening see anything that could help complete the timeline?
