University of Washington Police has finished an investigation of a shooting during a protest at the University of Washington and has handed over the case to the King County Prosecutor’s Office Wednesday.

Prosecutors will review the case and decide whether to file charges against the individuals involved.

Joshua Dukes, 34, was shot during a protest in UW’s Red Square January 20. The protest was against former Breitbart editor Milo Yiannopoulos. The far-right commentator was speaking at an event on campus that night.

Shortly after the shooting, Marc Hokoana and his wife Elizabeth, both 29, turned themselves in for the shooting, claiming it was in “self-defense.” UW police haven’t made any arrests.

UW policy prohibits guns being brought unto campus. A violation could mean being banned from campus. If the offender is a student, it could result in expulsion.
