The body of a Utah man was found in a freezer at his home — with a notarized letter stating his wife wasn’t responsible.

Paul Mathers’ frozen remains were found during a police search of his house in Tooele, Utah, where he had lived with his wife, Jeanne Souron-Mathers.

Mathers, who had been diagnosed with a terminal illness, was last seen at a Veterans Affairs medical center on Feb. 4, 2009. He is believed to have died between Feb. 4 and March 8 of that year.

Before he passed on, Paul Mathers wrote a letter stating his wife was not responsible for his death and got the letter notarized in December 2008, according to a search warrant.

“Detectives tracked down the notary and she said she didn’t read it, she just stamped it,” Sgt. Jeremy Hansen of the Tooele Police Department told CNN. Jeanne Souron-Mathers, 75, died in November from what appears to be natural causes, Hansen added.

Investigators are looking into whether monthly checks from Veterans Affairs and Social Security were still coming in after Paul Mathers died, police said.
