Scott Kimball is interviewed by FBI Special Agent Jonathan Grusing and Lafayette police detective Gary Thatcher at the Cascade County Detention Facility in Great Falls, Mont.

Asked about the disappearances of Jennifer Marcum, Kaysi McLeod and Terry Kimball, he offers to provide information about Jennifer and his uncle if given immunity for his white-collar crimes. Kaysi, he tells the investigators, is still alive.

During the six-hour interview, Kimball makes statements like: “I can’t incriminate myself any further” and “I wish I could be honest with you.”
