Following flared tensions and looting late Friday night, Missouri Gov. Jay Nixon has declared a state of emergency and is implementing a curfew in the St. Louis suburb where a black teenager was shot to death by a white police officer a week ago.
Nixon said Saturday that the state will not allow a handful of looters to endanger the community and that there must be calm if justice is to be served. The curfew will run from midnight to 5 a.m.
On Friday, police released the name of the officer who fatally shot 18-year-old Michael Brown, as well as documents and video alleging Brown robbed a store before he died.
Brown's shooting in the middle of a street following a suspected robbery of a box of cigars from a nearby market has sparked a week of protests, riots and looting in Ferguson.
Nixon also says the U.S. Department of Justice is beefing up its investigation of the shooting and there are dozens of FBI agents on the ground working on the investigation.
