The Kowalczk/Thompson Murders. An elderly couple was bludgeoned to death in their home, but the crime went unsolved. Two years later, the owner of a pawn shop was looking through a stack of old newspapers and came across an article about the murders. There was a photograph of the victims, and the woman pictured was wearing an unusual elephant pendant necklace – a necklace which the owner realized was in her shop. Not only that, she still had the pawn ticket, identifying who had sold the jewelry. (thetvdb.com)
