Tiffany Louise Sessions (born October 29, 1968)[1] is a missing woman from Tampa, Florida,[2] who was last seen on February 9, 1989.

[1] Sessions was wearing a white pullover sweatshirt with long sleeves and grey horizontal striping with "Aspen" printed on the front of the shirt's collar, red sweatpants, and tennis shoes.

She was also wearing a two-tone silver and gold women's Rolex wrist watch and was carrying a black Sony Walkman.

While Knickerbocker was in prison serving five consecutive life sentences, he reportedly told his fellow inmates that he had murdered Sessions.

As of 2014[update], police believe that now-deceased and convicted serial-killer Paul Eugene Rowles was responsible for Sessions' disappearance and murder.

Notably the book contained a notation "#2 2/9/89 #2",[17][18] believed by investigators to refer to Sessions' date of disappearance, and to identify her as Rowles' second victim.
