On June 21, 2010, 17-year-old Billy A. Moore was shot in the back after stepping off a TriMet bus near North Woolsey Avenue and Trenton Street in North Portland’s New Columbia neighborhood. He collapsed two blocks from McCoy Park and died that night; his mother also died that same night after he had visited her at OHSU. Police said the shooting followed a tense dispute on the bus and that a teenage suspect was identified and arrested within hours. Witnesses reported the shooter flashed a gang sign toward Billy moments before the shot.

Friends, relatives and church members described Billy as a devout Christian, a recent graduate and prom king of Rosemary Anderson High School who worked shifts with the Salvation Army and ran his church’s recording gear. The arrest was of a 17-year-old initially; court records show the defendant identified as 16-year-old Marsel Darvis Upton Jr. ultimately pleaded guilty to first-degree manslaughter and received a 19-year prison term in March 2011. The killing prompted public meetings, extra security attention in New Columbia and a City Council emergency measure to extend park-banning authority for excluded residents.

Did anyone hear or see the confrontation on the bus that afternoon or see Billy after he left the stop?
