KEOKUK, Iowa (AP) - Police in southeastern Iowa have arrested and charged a man in the 2004 death of a Keokuk woman.
On Tuesday, police arrested Nathanial Leo Ridnour, 34, in the June 2004 death of 73-year-old Bonnie Callahan, the Iowa Division of Criminal Investigation said in a news release. Ridnour is charged in a warrant with first-degree murder in the case.
Police said Callahan’s body was found along the bank of the Mississippi River front in Keokuk on June 15, 2004 - the same day her family had reported her missing. An autopsy showed she had been beaten to death. Ridnour had been a suspect at the time, but he wasn’t charged until after police reopened the investigation in 2017, the release said.
The DCI did not detail what evidence led to Ridnour’s arrest this week. The division said Ridnour’s arrest is the eighth related to its Major Crime Unit conducting cold case homicide investigations in a three-year period in the southeast Iowa area.
