Kelsey Grammer’s Heartfelt Letter About His Late Sister

ET has obtained a heartfelt letter written by actor Kelsey Grammer and read at the Monday parole hearing of the man who murdered his sister, Karen Elisa Grammer.

Grammer's letter, written to retired Colorado District Attorney Robert Russel, who successfully prosecuted the first-degree murder case against Freddie Glenn, reads in part:

"I am saddened that I missed this opportunity to be at the hearing. You know the circumstances: rain delays at Kennedy that made it impossible for me to be in Colorado Springs in time to attend…Please tell the members of the parole board that it is my sincere hope they do not release my sister's killer."
