Former Philadelphia police officer Edsaul Mendoza knew Thomas "T.J." Siderio, 12, was unarmed when he shot him in the back and killed him, Philadelphia District Attorney Larry Krasner said as he announced murder charges against Mendoza on Monday.
Police said Siderio had fired at a car carrying four officers before running away on March 1 — but Krasner said Mendoza, who chased Siderio on foot, knew the boy had thrown his weapon away before he shot him. Siderio was on the ground at the time, Krasner said.
