A man convicted of the 1975 murder of Kelsey Grammer’s sister was denied parole in a Colorado court today, the Associated Press reports. Freddie Glenn, 52, is serving a life sentence for the murder of 18-year-old Karen Grammer, who was abducted, raped and killed outside a Red Lobster in Colorado Springs by several men, including Glenn, who had planned to rob the restaurant. Grammer did not attend the parole hearing as he’d planned, said a Dept. of Corrections spokeswoman, having missed a connecting flight due to rain. The Frasier star’s family has been touched by multiple tragedies: Grammer’s father was murdered in 1968, and his twin half-brothers perished in a scuba diving accident in 1980. Update: Although bad weather kept him from being there in person, Kelsey Grammer did submit an email to the parole board at Limon Correctional Facility that may have helped deny the parole of his sister’s killer. has revealed some excerpts of the emotionally-charged statement, which the 54-year-old stage and TV actor had hoped to read before the parole board in person in Colorado on Monday afternoon, but Grammer ultimately had to cancel his travel plans due to torrential rainstorms.
