Part IV: Clue of the Killer’s CALLING CARD
See Parts I-III of this Real Detective article below.
The two officers went rampaging through the place, using their training to single out the obvious hiding places of so incriminating a piece of evidence as a murder gun. But they couldn't find it.
Then Dockum spied a suitcase which, when picked up, seemed fully packed. He pried its lock open, rummaged through an assortment of men’s clothing, and finally struck a hard metallic object with his hand.
The Norwood detective drew out a fully-loaded .38 caliber revolver. Familiar as he was with Anthony Overberg's .38, the officer could not believe he had it in his hand after two and a half years.
It took Kiley to verify the discovery. "Sure, there's Davis's special grips and Wilson's trigger guard!" he exclaimed. "Wait'll Fritz hears this."
Mrs. Linna Louise Carter, wife of the suspect, was revived and taken to Louisville headquarters. There, shown the weapon, she fainted again. With a doctor now in attendance, the wife refused, between sobs, to talk. But she did agree to go back to Norwood the following morning with Kiley and Dockum.
Her arrival on Saturday, January 20, was an event, what with half the city already celebrating, news of the case's solution. Flashlight bulbs popped and Mrs. Carter fainted twice more.
