TOPEKA, Kan. (AP) — Authorities have arrested a Kansas man in the killing of his wife in northeast Kansas.

Jackson County sheriff Tim Morse said in a news release that the 66-year-old man was arrested Tuesday. The Topeka Capital-Journal reports that the sheriff’s office received a 911 call in October from the couple’s home.

The husband told dispatchers he had found his 61-year-old wife unresponsive. She died the next day at a Topeka hospital.

The sheriff’s office opened an investigation, and an autopsy indicated the woman died from trauma to the spleen.

A search warrant on the husband’s residence was served Tuesday morning.
