DENVER —  Actor Kelsey Grammer is vowing to come to Colorado and speak for his sister if the man who killed her more than 30 years ago makes a bid for parole.

Fifty-year-old Freddie Lee Glenn is serving three life terms for several crimes, including the 1975 murder of 18-year-old Karen Grammer in Colorado Springs.

Police say Glenn and two other men kidnapped her as she walked into the Red Lobster restaurant where she worked -- after they attempted to rob it.

Glenn later slit Grammer's throat.

He was convicted of murder, second-degree kidnapping and armed robbery. Glenn was sentenced to death, but his sentence was commuted to life in prison due to changes in laws.

He'll be eligible for parole in January.

Grammer says he's still angry about Glenn. He also says he never had a chance to speak for his sister before, but will now if Glenn tries to get out of prison.

Glenn has until December to decide whether to waive or pursue the January parole hearing.

Grammer is best known for his role as Dr. Frasier Crane in the television series "Cheers" and "Frasier."

He stars in the new FOX series "Back to You," which debuts Sept. 19.
