Seward's son Augustus and Sergeant George F. Robinson, a soldier assigned to Seward, were alerted by Fanny's screams and received stab wounds in struggling with Powell. As Augustus went for a pistol, Powell ran downstairs toward the door, where he encountered Emerick Hansell, a State Department messenger. Powell stabbed Hansell in the back, then ran outside exclaiming, "I'm mad! I'm mad!" Screams from the house had frightened Herold, who ran off, leaving Powell to find his own way in an unfamiliar city.
