(CNN) When police were called to make sure a Utah woman was OK, officers found her dead and her husband's body inside a freezer.

Jeanne Souron-Mathers was found dead last week at her Tooele City apartment. A maintenance worker who was concerned about her well-being called police, saying he had not seen the 75-year-old woman for about two weeks, police said.

As a detective searched the apartment for any clues about Souron-Mather's death, he discovered a man's body inside a chest freezer, Tooele City police said in a statement Monday.

The man was the woman's husband, Paul Edward Mathers, 69, police said. "At this time, foul play is suspected and the case is in the early stages of investigation," police said.

The man's body was "fully intact" and police believe he could have been inside the deep freezer for at least a year and a half, but possibly up to a maximum of 11 years. It's unclear how authorities determined that time frame.
