Dallas police identify dead suspect as Micah Johnson

Micah X. Johnson, of Mesquite, is one of four people police said were responsible for ambushing police officers at a peaceful protest against nation-wide officer-involved shootings in Dallas Thursday.

Police said officers cornered Johnson and negotiated with him for hours before talks broke down. Dallas Police Chief David Brown said Johnson told officers he was upset about recent shootings involving police and “wanted to kill white people. Especially white officers.”
