Prison photo of Charles Hunter, who was convicted of a string of sexual assaults and home invasions that occurred in December 1978. Hunter received an indeterminate sentence, and has been eligible for parole numerous times over the years. Hunter is currently eligible for parole in June.

Convicted Lawrence serial rapist Charles Hunter was passed up for parole by the Prison Review Board, according to a Kansas Department of Corrections spokesman. The board passed Hunter, eligible for parole in June, for one year, meaning he’ll be eligible for parole again in 2013.

Hunter was convicted of a series of rapes and home invasions that occurred in December 1978 in Lawrence. In 2010, Hunter, with assistance from the New York-based Innocence Project, obtained a DNA test on two of the rape kits in the case. However, the testing was not able to exclude Hunter as the rapist.

Hunter originally was given a life sentence and was first eligible for parole after 15 years. The parole board repeatedly has denied parole for Hunter, who is incarcerated at Larned State Hospital, operated by the state corrections department.
