Part II: Clue of the Killer’s CALLING CARD
By morning the haggard, sleepless police of both cities found themselves empty-handed in more ways than one. Not only were they lacking a definite suspect, but the fingerprint men had found no worthwhile impressions either in the drugstore or on the .45 caliber pistol dropped by the slayer.
Fritz, before retiring for a few hours of needed rest, dispatched the weapon's serial number to the manufacturers, asking for the name of the dealer to whom it had been sold.
By nightfall, back on the job, he learned the gun was part of a consignment to a Louisville, Kentucky, sporting goods establishment which had gone out of business within the past year. Contact with a member of this firm revealed that no records of gun sales had been kept.
Fritz was disappointed.
To make his disappointment more keen, Fritz's pawnshop squad reported no results in connection with the Overberg pistol. The bandit apparently had made no effort as yet to dispose of it. Fritz ordered the weapon's description circularized to police departments throughout the by middlewest.
By this time, the Sergeant Overberg slaying had stunned the city of Norwood and brought its 35,000-odd citizens rallying to the raising of a fund to aid Overberg's young widow and her two small children, Carole Ann and Kathleen.
In addition, rewards totaling $700 were immediately offered for the apprehension of the slayers. Soon business firms began contributing sums until the price on the killer's head went over the $2,500 mark.
