Eighteen-year-old Karen Grammer was abducted on July 1, 1975, outside a Red Lobster restaurant after an attempted robbery. She was raped and stabbed in the throat and back.
Fifty-two-year-old Freddie Glenn, who is serving a life sentence in Karen Grammer's slaying, is eligible for parole.
A Department of Corrections spokeswoman says Grammer plans to attend Monday's hearing at the Limon Correctional Facility in Limon, about 90 miles southeast of Denver.
Colorado law no longer allows parole for those sentenced to life in prison for first-degree murder. Glenn was convicted before the Legislature changed the law in 1990, so it doesn't apply to his case.
