The ambush began with gunshots that killed five officers and sent screaming crowds scrambling for cover. It ended when a Dallas police bomb squad robot killed a gunman after negotiations failed.
Investigators identified the dead suspect as 25-year-old Micah Xavier Johnson of Mesquite, Texas, a military veteran who’d served in Afghanistan. Police said they searched his home Friday afternoon and found bomb-making materials, ballistic vests, rifles, ammunition and a personal journal of combat tactics. Investigators are analyzing information in the journal, a police statement said.
