'He almost decapitated her': 'Frasier' actor recalls sister's brutal murder

In an exclusive interview with People magazine, actor Kelsey Grammer recalled his sister's final moments before she was murdered.

“For a long time, the grief was so dominant that I couldn’t access happiness,” Grammer told people. "The book helped me get to a new place with that.”

Grammer's new book Karen: A Brother Remembers delves into “the horrific details of his sister’s murder,” People said, “as well as the deep and lasting toll it took on his life, which has been touched by multiple tragedies.”

His father, Allen, was shot and killed at his home in St. Thomas by a taxi driver in 1968. Grammar was 12 at the time. His half-brothers, Billy and Stephen, were killed in a suspected shark attack while scuba diving in the Virgin Islands in 1980.

However, it was the July 8, 1975, murder of Karen that Grammer spoke about the “lasting impact” of.

The now 70-year-old grappled with including “the ‘graphic, impersonal review’ of Karen's last moments from the police report in the book.”

According to People, “Though delving into the details was ‘not pleasant or comforting,’ he ultimately decided ‘there is something beneficial in knowing [the truth]. It is ammunition to keep Freddie Glenn in jail.’”

“You don’t want to eat yourself to pieces because you can’t forgive somebody,” he said. “But it’s hard to forgive a person who consciously decided they wanted to murder somebody you love. This wasn’t just some temperance issue with him. It was deliberate. I can give you forgiveness, but you’re not going to get out of paying for it.”

People released an exclusive excerpt of the book, which in part says: “The coroner noted that through a gaping wound in her neck, he could see all the way into Karen’s lung. I had been right in saying he almost decapitated her.”

Karen: A Brother Remembers comes out May 6.
