The slain bodies of an elderly married couple were found in their home Monday in the northwest Iowa town of Gruver. Emmet County authorities responded to the home after getting a 9-1-1 call. The sheriff says Marvin and Laura Cox, both 74, had been shot to death with a 22-caliber rifle.

Nearby residents were evacuated. The man’s body was found on the kitchen floor while the woman’s body was in a living room chair, in what appears to be a murder-suicide. The Iowa Division of Criminal Investigation was called to assist in probing the double-shooting.
