Damage shown from blast that stopped police-killing sniper


DALLAS (AP) — A bomb delivered by a police robot that killed a sniper, ending a deadly ambush on Dallas police, caused severe damage to a hallway at a downtown Dallas community college building.

El Centro College officials displayed the damage to reporters on Tuesday. Bloodstains and most debris had been removed from the blast that killed Micah Johnson, but a doorframe was blown from its wall, wires and metal hung from a ceiling without tiles, and wallboard was ripped from frames.

For about four hours, Johnson hid around a corner at the end of a hallway of classrooms after fatally shooting five police officers July 7. The standoff ended early July 8 when police detonated what they said was about a pound of C4 explosive delivered by a police robot.
