GRAYLAND, Wash. -- A 59-year-old woman has turned herself in to police after she was wanted as a person of interest in the death of her boyfriend in Grays Harbor County.

Police were looking for Sherry Hamm to question her in the disappearance and now death of her boyfriend, 62-year-old Kenneth Hutchinson, said Undersheriff Rick Scott.

A man’s body was found Monday wrapped in several plastic bags under the trailer in Grayland where the two lived, Scott said. The coroner has now positively identified the body as that of Hutchinson.

Hamm turned herself in to Clark County police Thursday afternoon.

Grays Harbor deputies discovered the body after they responded to a call from the trailer park manager who noticed the opening beneath the trailer covered -- as if to hide something, police said.

While a police officer was looking around outside of the home, he discovered the plastic bag with human remains under the trailer, Scott said.

Police said Hutchinson was last seen Aug. 6, and that Hamm disappeared three days after that.

The couple had been together for 30 years.

A warrant was also issued for Hamm’s arrest because she disappeared while awaiting sentencing for assaulting her boyfriend's brother with a claw hammer and a knife, police said.

Sheriff’s deputies are heading to Clark County to interview Hamm.
