NORTH PLATTE, Neb. (AP) — A judge has postponed an annual review hearing for a man who killed six members of a western Nebraska family in 1975.

Lincoln County District Judge Donald Rowlands rescheduled the hearing for Erwin Simants to Nov. 18.

Simants has lived at the Lincoln Regional Center since 1979, the year he was found not guilty by reason of insanity for the shooting deaths of six in the Kellie family of Sutherland. Prosecutors say Simants shot and killed Henry and Audrey Kellie; their son David; and three of their grandchildren in 1975.

Doctors testified last year that Simants is no longer mentally ill, but the judge ruled that he still would pose a threat to the public if released.
