The Illinois State Police said Wednesday that they've arrested Deborah Dewey's brother-in-law in connection with her disappearance and death.
Standard, Ill., resident Clifford Andersen, 66, is charged with concealment of a death, a class-four felony, and is being held in the Bureau County Jail on $750,000 bond.
Dewey's body was found Monday in a shallow grave on a vacant property in Standard. The 62-year-old Ladd woman had been missing since Aug. 22, when she failed to report to work. Her unlocked car was found at a truck stop in Morris on Aug. 29.
