ROCKLAND, Maine (AP) — A Maine woman has pleaded guilty to killing an elderly woman who was found unresponsive in her home in Owls Head.

Sarah Richards, of South Thomaston, pleaded guilty Thursday to murder in the February 2019 bludgeoning death of 83-year-old Helen Carver. No sentencing date has been set.

The two women knew each other because Richards had been hired to shovel Carver’s driveway and walkway during the winter.

Carver’s sons said their mother suspected that Richards had stolen a debit or a credit card from her. They said Carver reported the alleged theft to police.
