FERGUSON, Mo. (AP) -- Missouri's governor today ordered the National Guard to a St. Louis suburb convulsed by protests over the fatal shooting of an unarmed black teen, after a night in which police used tear gas to clear protesters off the streets well ahead of a curfew.
Gov. Jay Nixon said the National Guard would help "in restoring peace and order" to Ferguson, where protests over the killing of 18-year-old Michael Brown by a white police officer entered their second week. Police said they acted in response to gunfire, looting, vandalism and protesters who hurled Molotov cocktails.
"These violent acts are a disservice to the family of Michael Brown and his memory and to the people of this community who yearn for justice to be served and to feel safe in their own homes," Nixon said in a statement.
The latest confrontations came on the same day Attorney General Eric Holder ordered a federal medical examiner to perform another autopsy on Brown, and as a preliminary private autopsy reported by The New York Times found Brown was shot at least six times, including twice in the head.
As night fell in Ferguson Sunday, another peaceful protest quickly deteriorated and the streets were empty well before the midnight curfew.
"Based on the conditions, I had no alternative but to elevate the level of response," said Capt. Ron Johnson of the Missouri Highway Patrol, who is in charge of security in Ferguson. At least two people were wounded in shootings by civilians, he said.
The "extraordinary circumstances" surrounding Brown's death and a request by his family prompted the Justice Department's decision to conduct a third autopsy, agency spokesman Brian Fallon said in a statement. The examination was to take place as soon as possible, Fallon said.
The results of a state-performed autopsy would be taken into account along with the federal examination in the Justice Department's ongoing civil rights investigation, Fallon said.
Dr. Michael Baden, a former New York City chief medical examiner, told The New York Times that one of the bullets entered the top of Brown's skull, suggesting his head was bent forward when he suffered a fatal injury.
Brown also was shot four times in the right arm, and all the bullets were fired into his front, Baden said.
The Justice Department already had deepened its investigation into the shooting. A day earlier, officials said 40 FBI agents were going door-to-door gathering information in the Ferguson neighborhood where Brown was shot to death Aug. 9.
