Tecumseh ? Shawnee County authorities say the death of a Tecumseh couple last week likely was a murder-suicide.

The county sheriff’s office says in a news release that an investigation indicated 57-year-old Andrew Jackson Jr. killed his estranged wife, 52-year-old Carolyn R. Jackson, and then killed himself. Their bodies were found in their home last Tuesday.

Authorities have not said how the couple died.

The Topeka Capital-Journal reports the couple was separated and going through a divorce. They had been married 30 years and had three adult children.

The sheriff is waiting for reports from the county coroner before making a final ruling.
