Excerpt from dispatch about Saray's killing:

Fifteen-year-old Saray Rivas was shot and killed in a part of Los Angeles where residents are afraid to talk, where silence eats up questions about immigration status, gang violence and even murder.

Saray lay in a pool of her own blood for more than 12 hours after being shot in an Arlington Heights apartment because nobody wanted the police around asking questions, witnesses said.

When police did come, they were met with silence.
