Timothy Haverkamp, convicted of second-degree murder in 1985 for his role in the cult-related murder of two people near Rulo, is one of several inmates working at the mansion under a decades-old arrangement with the state’s work release program, Department of Corrections spokeswoman Connie Nemec said.

Interviews with the authorities, relatives of the Rulo farm’s residents and neighbors create a picture of weapon stockpiles, religious fanaticism and anti-Government sentiment. The farm’s recent residents have been linked by the authorities and family members to an anti-Semitic, white supremacist religious movement, the Ministry of Christ Church, which is called Identity after its publication, and to an allied group, the radically antitax, anti-Government Posse Comitatus.
