An accomplice in the 1975 murder of Frasier star Kelsey Grammer’s sister in Colorado Springs has died in prison.
64 year old Michael Corbett died Monday night of natural causes.
Grammer’s sister, Karen, was murdered in 1975 after leaving the Red Lobster restaurant where she worked.
Corbett and Freddie Glenn had planned to rob the restaurant, but kidnapped Grammer, repeatedly sexually assaulted her, and stabbed her multiple times.
Grammer’s murder was the third in a killing spree.
Corbett and Glenn both received the death sentence, however the sentences were commuted to life in prison.
Glenn comes up for parole in 2021.
