Death and legacy
Prior to January 17, 2526, Dominguez and Lance Corporal Chris Preston were assigned to a freighter that was fleeing the destruction of Harvest. At some point when they were fleeing the freighter was boarded by Covenant boarding craft. According to Preston, Dominguez led Preston against the boarders, saving lives and recovering vital technology.
