Kelsey Grammer doesn't want to see his sister's Killer leave prison. On Wednesday the 59-year-old actor testified against 57-year-old Freddie Glenn who raped and killed the star's sister Karen Elisa Grammer in 1975 when she was leaving her job at a Red Lobster in Colorado Springs. 'I accept that you live with remorse, but I live with tragedy every day,' the Cheers star said via satellite at a Colorado parole hearing. 'I accept your apology. I forgive you. However, I can**t give your release my endorsement.'
