Eight days later, Glenn and Corbett met Winfred Proffitt, age 19, another Fort Carson soldier, at Prospect Lake.
Glenn, Corbett, and two other men decided to rob a Red Lobster restaurant, located on South Academy Boulevard.
Glenn, who according to court testimony had taken LSD,[2] stabbed Grammer in the throat, back and hand, and left her to die.
[3] For a week, police were unable to determine who she was until her roommate at the time called to report her missing and subsequently identified her.
[2] Glenn was convicted in 1976 for the murders of Daniel Van Lone, Winfred Profitt, and Karen Grammer.
Judge Hunter Hardeman, noting "there was no rhyme or reason for what happened," sentenced Glenn to the gas chamber for Karen Grammer's murder.
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.
Instead, Grammer sent a letter to Robert Russel, the retired El Paso County, Colorado District Attorney who successfully prosecuted Glenn.
"[5] According to his letter to Russel, Grammer described his sister, who had graduated from high school and decided to take a year off after she attended a semester of college.
At that parole board hearing, Kelsey Grammer delivered an emotional testimony via video conference, where he offered forgiveness after being convinced that Glenn was remorseful for killing his sister.
