In September, Bundy sold his Volkswagen Beetle to a Midvale teenager. Utah police impounded it, and FBI technicians dismantled and searched it. They found hair matching samples obtained from Caryn Campbell's body. Later, they also identified hair strands "microscopically indistinguishable" from those of Melissa Smith and Carol DaRonch. FBI lab specialist Robert Neill concluded that the presence of hair strands in one car matching three different victims who had never met one another would be "a coincidence of mind-boggling rarity".
