The feds want to perform their own autopsy on Michael Brown, the unarmed teen shot dead by local police in Ferguson, Missouri, a week ago.

“Due to the extraordinary circumstances involved in this case and at the request of the Brown family, Attorney General Holder has instructed Justice Department officials to arrange for an additional autopsy to be performed by a federal medical examiner,” Justice Department spokesman Brian Fallon said in statement. “This independent examination will take place as soon as possible. Even after it is complete, Justice Department officials still plan to take the state-performed autopsy into account in the course of their investigation.”
