U.S. Attorney General Eric Holder has ordered a federal autopsy for Michael Brown, the 18-year-old who was shot and killed in Ferguson, Mo., Aug. 9. St. Louis County police did not release the results of the full autopsy last week, citing the need to wait for toxicology test results, but confirmed Brown died of gunshot wounds.

U.S. Justice Department representative Brian Fallon discussed Holder’s move in a couple of tweets Sunday:

Ben Crump, the Brown family’s lawyer, spoke to the Associated Press Thursday and said they wanted a second, federal autopsy to be conducted before a funeral.

“As Attorney General Holder has indicated, the Department of Justice is investigating the situation along with local officials, and they will continue to direct resources to the case as needed. I know the events of the past few days have prompted strong passions, but as details unfold, I urge everyone in Ferguson, Missouri, and across the country, to remember this young man through reflection and understanding,” President Barack Obama said in a statement Wednesday.

Earlier Sunday, Missouri Gov. Jay Nixon criticized the release of a security video by Ferguson police and said he ordered a curfew to allow dual investigations by the FBI and local authorities to continue and to eventually have justice served.
