Oscar Carrillo, 26, called police last Saturday and told emergency dispatchers that he was robbed at gunpoint by two men.
Police said it was that initial report that led two officers to fatally shoot Kendrec Lavelle McDade, 19, when they saw him running shortly after 11 p.m. on Sunset Avenue near Orange Grove Boulevard. Officers said they saw him reach for his waistband.
“The officer had no time to exit the vehicle. Fearing for his life, given the basic information of the call, the first [set] of rounds were fired,” Pasadena Police Chief Phillip Sanchez said at the community meeting to discuss the investigation at the New Revelation Missionary Baptist Church at 55 North Orange Grove Boulevard.
Carrillo later admitted that he lied – the suspects were, in fact, not carrying guns and they took a backpack from his car. He reportedly said the suspects were armed so officers would respond more quickly.
