On the evening of April 24, 2007, 29-year-old Robert Edward Gonzalez was found lying on the side of the road in the 2300 block of University Boulevard in Adelphi, Maryland, with a gunshot wound to his upper body. He was taken to a local hospital and pronounced dead shortly after arrival.

Prince George’s County investigators identified a suspect within days and arrested 22-year-old Dimas E. Cruz of Hyattsville. Cruz was charged with first-degree murder and held without bond. Investigators say the shooting followed an encounter in which Gonzalez allegedly flashed a gang sign at Cruz.

If anyone saw or has information about the events on University Boulevard that evening, please share what is known with investigators.
