BOISE, Idaho (AP) — A 61-year-old southwest Idaho man police say killed his 87-year-old father has pleaded not guilty to first-degree murder and other charges.

Anthony Wayne Conner of Meridian made the plea Tuesday in 4th District Court. Conner was arrested Oct. 14 after a grand jury indicted the younger man on charges of first-degree murder, grand theft, forgery and concealing evidence. Police started investigating after Anthony Conner reported finding his father, Otis Conner, dead and said the elderly man had fallen from a ladder.

A coroner ruled Otis Conner's death was caused by blunt force trauma to the head. Anthony Carter is being held in the Ada County Jail on $1 million bond.
