The event took place during "Kraven's Last Hunt", a story arc that ran through two issues each of the late
'87 Spidey-titles. In it, Kraven has been driven insane, believing that Spider-Man is his own personal
demon that has haunted him and his family for their entire lives. In order to exorcise that demon, Kraven
believed he had to not only triumph over the Spider, but to successfully re-place him.

To this end Kraven drugged Spider-Man, buried him alive for two weeks, and then donned Spidey's
costume to take his place. After beating Vermin, a mutated man-creature whom Spider-Man only beat with
Captain America's help, Kraven believed he had beaten his own demon.

He then made peace with Spider-Man and with himself, and used a rifle to take his own life.
