Did Sister of Idaho Murders Suspect Fear He Was the Killer?

Long before cops charged Bryan Kohberger with the murders of four University of Idaho students, his own family feared he was the killer. Howard Blum says in his new book "When the Night Comes Falling," that Kohberger's sister became convinced he was the killer after police launched a nationwide search for a white Elantra. The book claims that Kohberger's sister confronted their father with her worst fears but her father turned his back and walked away.
