In the 1970s, Glockner worked as a nurse at the Green River County Detention Center. Glockner hated criminals and started targeting them for death, taking cons that came into her infirmary for simple colds and poisioning them so that they had a heart attack. While stories went around, no one could ever prove anything about it. During this time Glockner met Randall and while giving him a tetanus shot, nearly put her needle through his arm. However, Glockner spared Randall's life. During a prison riot in 1976, a bunch of prisoners took Glockner into an isolation cell in the old cell block and bashed her head in in revenge for her murders. Glockner was then buried in Green Valley Cemetery.
Following her death, Glockner became a violent spirit. However, she somehow got trapped in the cell she was murdered in. In 2007, the old cell block was reopened and Glockner was released when the cell her spirit was trapped in was opened. That night, Glockner murdered a guard who was crooked by inducing a heart attack as witnessed by Randall. Over the next three months, Glockner murdered three more people.
After the four murders, the warden of the detention center, Deacon, called in hunters Sam and Dean Winchester to get rid of the ghost haunting his prison. The Winchesters wrongly assumed Glockner was actually the spirit of serial killer Mark Moody however. While Dean was in solitary, Glockner murdered a prisoner named Lucas which Dean witnessed but continued to wrongly assume it was Moody. Glockner later attacked the infirmary where Dean and Tiny were being held. Though Glockner went after Dean, he was able to repel her with salt. Glockner then killed Tiny instead. With the help of Randall and Mara Daniels, the Winchesters were able to figure out Glockner was their ghost and escape from prison with the help of Deacon.
At the same time the Winchesters dug up her bones, Glockner attacked Deacon in the prison bathroom, enraged that he let the Winchesters go. As Glockner started to induce a heart attack in Deacon, the Winchesters dug up her bones and salted and burned them. In immense pain, Glockner released Deacon, backed up and went up in flames, saving Deacon's life.

- The reason Glockner's ghost was trapped isn't revealed but its possible it was because the cell she was killed in was sealed and had an iron door, a weakness for ghosts. The reason for the cell block being sealed was never given, but it was possibly due to the riot that killed Glockner which occurred shortly after the death of Mark Moody. Both events are stated to have taken place right before the cell block was sealed.
