(Updated: Police chief says officer was not aware Brown was a robbery suspect when he stopped him.)
Police in Ferguson, Mo., allege that unarmed teenager Michael Brown robbed a convenience store of cigars before he was shot and killed by a police officer.
In a news conference Friday morning, Ferguson Police Chief Thomas Jackson released the name of the officer who shot Brown on Saturday, as well as an incident report saying the 18-year-old was suspected of committing the robbery just before the shooting. Police also released surveillance images that they said showed Brown towering over a store clerk and shoving him.
