CANAAN (AP) – State troopers and game wardens returned to the woods of Canaan on Wednesday but the search failed to yield evidence of Shirley Moon Atwood, who has been missing since last month, officials said.

State police detectives realized Atwood was missing while investigating Friday’s discovery of a body believed to be that of Cheryl Murdoch.

Murdoch had been living with Atwood’s estranged husband, Shannon Atwood. It’s unclear whether Shirley Atwood had moved out but it was remained her legal residence, said Stephen McCausland of the Maine Department of Public Safety.

Shannon Atwood, who used a bow and arrow to threaten detectives who came to search his house Sunday evening, was being held on $20,000 bond at the Somerset County Jail on charges of terrorizing and reckless conduct.

Shannon Atwood has not been described as a suspect in either Murdoch’s homicide or Shirley Atwood’s disappearance, but he and the house were connected to both women. “That’s the last known address of both women,” McCausland said.

Investigators remain concerned for the welfare of Shirley Atwood, and they believe she holds information that’ll be of interest to detectives. “Once she’s located, we hope many of our questions may get answered, he said.
