Willard Woodring, 42, and Richard Buchanan, 49, were found bound, gagged and shot to death in the kitchen of the Hawkeye Hotel, a well-known house of prostitution, in Keokuk on Sunday, Oct. 9, 1960.
Police immediately launched a three-state search for a young couple who witnesses reported seeing leave the building shortly before the double slaying was reported.
Witnesses described the man as about 25 years old with black hair and clad in a black leather jacket. The woman, about 22-23 years old, was described as having short red hair and wearing a lavender dress. They were thought to be driving a car with Illinois license plates.
Police believe robbery was the motive for the crime and that the killer may have been an acquaintance of Woodring.
There were few signs of a struggle in the room where Woodring and Buchanan were shot and, according to investigators, the murderers “seemed to know what they were doing.”
