Blank has been seen intermittently throughout the film cleaning up after his murders. As Delaney closes in on him, Blank attempts one more attack, but it does not go as planned. After striking several blows, his victim escapes only to be hit by a passing car. Delaney's investigation of Blank confirms that he is the killer. Delaney realizes that his chances of arresting and obtaining a murder conviction against Blank are slim due to Blank's wealth and high social position in the city. Before going to confront Blank in his luxury apartment, Delaney gets a Luger nine millimeter pistol from a closet in his home. It is a souvenir that Delaney brought home as a soldier returning from World War II.
