Police have identified a man fatally shot on a street in the Walbrook community Tuesday night as Rubin Nelson, a 26-year-old who lived in the 3100 block of Clifton Ave. Southwestern District officers found Nelson bleeding from multiple gunshot wounds in the 1900 block of N. Rosedale St., and he was pronounced dead at the scene by city Fire Department medics. Police had no suspects and knew of no motive. Nelson was convicted on drug charges in 2002 and received a seven-year suspended sentence, and in 2003 was found not guilty on handgun charges. He had not been charged with a crime since then, according to electronic court records.
