A Nebraska man convicted for his role in two grisly cult-related murders in 1985 is asking the state to end his lifetime parole supervision.
Timothy Haverkamp has asked the Nebraska Board of Pardons to commute his second-degree murder sentence of 10 years to life, and on Dec. 11, the board will consider whether to grant him a hearing.
Haverkamp was paroled in 2009 after spending 23 years in prison for his role in the murder of a fellow cult member, 25-year-old James Thimm.
Haverkamp testified against cult leader Michael Ryan, who remains on Nebraska's death row.
The 51-year-old Haverkamp was the subject of controversy in 2008 when officials confirmed he was one of several inmates giving tours of the Governor's Mansion while serving participating in a prison work release program.
