Brave Man Holds Suspect at Bay After He Stabbed Girlfriend to Death

An armed good Samaritan is being hailed a hero for keeping a man holding a knife at bay until police arrived. Suspect David Lee Morris, 29, allegedly stabbed his girlfriend at the Seattle Center Armory on Friday and then ran away, covered in blood. Scott Brown, who works at the Armory's food court, chased after him and caught up, pointing his gun at him and shouting for him to get on the ground. Video shows Brown training his weapon, for which he has a concealed carry permit, on Morris.
