U.S. Attorney General Eric Holder has asked for the Justice Department to arrange an autopsy on the body of Michael Brown by a federal medical examiner.
Justice Department spokesman Brian Fallon said in a news release on Sunday that Holder asked for the additional autopsy because of the "extraordinary circumstances involved in this case" and at the request of Brown's family.
The 18-year-old Brown was shot and killed by a Ferguson, Missouri, police officer on Aug. 9. Brown was black and unarmed. Officer Darren Wilson is white.
Fallon says the autopsy will take place as soon as possible.
He also said the Justice Department will still take the state's autopsy into account during the investigation.
