TOPEKA, Kan. (AP) — The family of a Topeka man who was killed before having his tattoos cut off and teeth pulled is angry and stunned that the killer will be released on parole.

The family of 33-year-old Charles Duty, who died in 1992, was notified Wednesday that Kenneth Cook has been granted parole. A specific date for his release has not been determined.

Cook, now 59, is serving a 15-year to life sentence for Duty’s killing. Investigators say Cook killed Duty while he slept, then cut off his tattoos, pulled his teeth and threw his body in the river.

The Topeka Capital-Journal reports Cook’s original “Hard 40” sentence and a first-degree murder conviction were overturned. He was retried and given a sentence making him eligible for parole after 15 years.
