Lawrence Kane is a favorite Zodiac suspect among numerous researchers and members of law enforcement. He was a mentally unstable individual with a troubling criminal history who lived in the Bay Area at the time of the murders. Although there isn’t a slam-dunk case against Kane as Z, he is definitely suspect number 1 in the mysterious disappearance of Donna Lass, a young nurse in Lake Tahoe. So if Kane killed Lass and Kane is Z, the pool of potential victims in the case begins to widen, as does the geographic scope of Z’s crimes. Kane suffered brain damage from a car crash that reportedly hindered his capacity for self-control.
