In 2009, Glenn was denied parole once after the Colorado Parole Board received a letter from Karen's brother, actor
Kelsey Grammer, who described Glenn as a "butcher" and a "monster". The board also heard testimonies from several other relatives of the victims and from detectives before deciding not to release Glenn from prison. Grammer had originally planned to attend the hearing at the state's
Limon Correctional Facility, but a rain delay caused him to miss a connecting flight to
Denver. Instead, Grammer sent a letter to Robert Russel, the retired
El Paso County, Colorado District Attorney who successfully prosecuted Glenn. During the hearing, Glenn told the board, "I apologize for my participation in something so terrible. I am sincerely and truly remorseful." In his letter to Russel, Grammer described his sister, who had graduated from high school a year earlier and decided to take a year off after attending a semester of college. He said that she may have moved to Colorado Springs because of a boy she liked. Grammer wrote: In 2014, Glenn was eligible for parole, but he was denied twice, and his request was deferred for three years. At that parole board hearing, Kelsey Grammer delivered his emotional testimony via video conference, where he offered forgiveness after being convinced that Glenn was remorseful for killing his sister. However, Grammer has said that Glenn should stay behind bars and serve out the remainder of his life sentence. In 2017, Grammer repeated his position when Glenn became eligible for parole again, in which he stated that Glenn would not deserve freedom in the future. Glenn was denied parole again in 2022 and will have another hearing in 2027. ==References==
