(CNN) -- Five former security guards from Blackwater Worldwide turned themselves in to federal authorities Monday in Salt Lake City, Utah, over charges stemming from the 2007 shootings in Baghdad that killed 17 Iraqis.
The Justice Department on Monday plans to charge the former guards with manslaughter and a weapons charge of using a machine gun while committing a crime of violence, a source with knowledge of the investigation said.
A sixth Blackwater guard tied to the incident has reached a plea deal with the government, a source said.
The Justice Department ordered the guards to surrender by Monday or face arrest. One of the guards is from Utah.
