The FBI and local law enforcement held a recent press conference on the 40-year anniversary of the abduction and murder of University of Idaho student Kristin David. The 22-year-old was found dismembered in the Snake River. Her case is one of several that occurred in roughly the same area, around the same time, that remain unsolved. Has one person gotten away with multiple murders, or could the LC Valley have been home to more than one killer capable of unthinkable evil? It's a question that haunts the community decades later.
