TOPEKA (AP) – Shawnee County authorities say a man and woman found dead at their Topeka home were separating after more than 30 years of marriage.

County sheriff’s Lt. Jay Simecka says the coroner has not determined the cause of death for 57-year-old Andrew Jackson Sr. and 52-year-old Carolyn R. Jackson. Their bodies were found in their home Tuesday evening. No one else was in the house.

The Topeka Capital-Journal reports court records show Carolyn Jackson filed a petition for separation maintenance March 16.

Records indicate the couple had three adult children.
