The Wisconsin Department of Justice on Wednesday identified the officer who shot Jacob Blake as Officer Rusten Sheskey. Hours later, the Department of Justice announced that the shooting, which led to three nights of violence in the state, is now under a federal civil rights investigation.

The state’s DOJ said in a press release that officers from the Kenosha Police Department were dispatched to the area on Sunday after a caller reported that her boyfriend, who was not supposed to be on the premises, was present.

The release did not specify what role Blake played in the original incident, but family attorney Benjamin Crump said he was attempting to break up a domestic dispute. Officers attempted to arrest Blake during the incident and used a Taser in an unsuccessful attempt to subdue him, the DOJ said.
