A Department of Homeland Security investigation of the shooting found two agency law enforcement personnel fired their guns during the agency’s deadly shooting of Pretti, according to a copy of the internal investigation obtained by USA TODAY.

The investigation performed by Customs and Border Protection’s Office of Professional Responsibility notes that the agency members began firing after an agent yelled "he’s got a gun" multiple times. The report does not say the bullets from both agency members hit Pretti.

Agency personnel began firing about five seconds after the agent yelled about Pretti’s gun, the report notes.

Border Protection’s preliminary findings were based on body-worn camera footage and agency documentation, according to the report.
