When the two officers arrived, they apparently saw Keith Lincoln sitting in the front room of the rental home, with a circular power saw. He then turned it on, and in front of police, cut off his own leg.

WBZ-TV’s Bill Shields reports.

“This was traumatic for the officers, ” said Plymouth Police Chief Mike Botieri. “To see a man take his own life in such a manner.”

The officers rushed into the home and tried to stop the bleeding, but it was to no avail. Lincoln later died.

But, the horrifying scene wasn’t over for the officers. They checked the bedroom and found Jetti Lincoln dead in a bed, along with the couple’s two dogs, who were also dead. She had been deceased for several days and may have died at the hands of her husband, using that power saw.

WBZ NewsRadio 1030’s Bernice Corpuz reports.

The couple rented the home last July, and neighbors found them to be quiet, yet friendly enough.

“They seemed happy, and told me they wanted to stay indefinitely,” said Marie Cesati.

The owner of the home Tim Moll told WBZ NewsRadio 1030 the couple was from Vermont and was behind on their rent.

Police are now trying to positively identify Jetti Lincoln through her dental records.

It’s not known if that was a factor in the murder-suicide.
