1 November 2019: A single consumer record in Infogroup’s Polk City Directories was the tipping point that helped South Dakota police identify the killer in a cold case murder.
Rapid City Police Detective Wayne Keefe used the directories to cross-reference case information in the 1968 slaying of Gwen Miller, a 60-year-old pharmacist.
“I made a great deal of use of the Polk Directories throughout this whole case just locating people,” Keefe told SBPD Radio during an interview in June. “The nice part of it is you can go back to those books, and you can see where people were living in any particular time, what they were doing, and where they were working.”
