A man involved in an evening shooting outside Vancouver’s Washington Elementary School and a separate robbery was sentenced Friday in Clark County Superior Court to 4.5 years in prison.Angelo Paga, 20, entered an “in re Barr” plea to first-degree rendering criminal assistance in the shooting, which allows a defendant to plead guilty to a lesser related charge he didn’t commit in order to avoid conviction for a greater offense. He also entered an Alford or Newton plea to first-degree robbery and theft of a firearm, acknowledging that a jury could find him guilty of those crimes but not admitting to guilt.A co-defendant in the shooting, 16-year-old Quandre O’Neal, previously pleaded guilty in juvenile court to first-degree assault with a firearm enhancement and was committed to a juvenile institution until his 21st birthday, Deputy Prosecutor Patrick Robinson said in a Friday interview.Another juvenile, 17-year-old Klay Mantanona, is still facing charges in both cases.At about 5:40 p.m. June 13, a physical and verbal fight broke out between two groups who met up at the school. Mantanona allegedly pulled out a 9 mm handgun, pointed it at the opposing group of juveniles, and fired multiple shots, according to a probable cause affidavit. No one was injured.Mantanona, O’Neal and Paga, who were all together, fled to Paga’s vehicle and sped away. Police later stopped them at Fruit Valley Road and West Fourth Plain Boulevard, the affidavit said. Police said they found Paga to be in possession of an illegal set of brass knuckles.
