A photo of Sullivan, who would now be 76, shows him sporting a similar haircut and a pair of thick glasses eerily similar to those seen in a police sketch of the Zodiac killer. His current location is unknown.

So far the Zodiac killer has been linked to five murders between December 1968 and October 1969 but it is believed he may be responsible for even more killings stretching into the early 1970s.

One of those is the murder of Bates, who was found with stab wounds similar to those of other confirmed victims of the Zodiac.
