Police in riot gear fired tear gas to try to disperse a crowd in a St. Louis suburb where an unarmed black teenager had been fatally shot by a police officer over the weekend.

Between two nights of unrest, a community forum hosted by the local NAACP chapter Monday drew hundreds to a sweltering church in Ferguson, the St. Louis suburb where 18-year-old Michael Brown was shot multiple times.

Witnesses have said that Brown had his hands raised when the unnamed officer approached with his weapon drawn and fired repeatedly.
