Thayne Ormsby, 20, of Orient, was arrested Friday in Dover, N.H., where he was held on a fugitive from justice charge. He’s charged in Maine with three counts of murder in the Amity stabbings of Jeffrey Ryan, 55, whom he thought was dealing drugs, as well as Ryan’s 10-year-old son and a neighbor, a police affidavit said. A 911 call on June 23 led police to the bodies.

Ormsby told police he had been staying in Orient in June with Robert and Joy Strout. He left on June 25, when Robert Strout drove him to Dover to stay with a relative.

Ormsby told police he had planned to move back to Weston, Maine, to fix up the home of one of Strout’s daughters, Tamara Strout, and live there with her and her daughter, the affidavit said. The Bangor Daily News reported Saturday that the daughter is 16 and her father was Jeffrey Ryan.

Dover police weren’t sure whether Ormsby has a lawyer. He is scheduled to be arraigned Tuesday on the fugitive from justice charge.

Ormsby said he never threatened any member of the Strout family after the stabbings. But according to the affidavit, Robert Strout said Ormsby told him he would kill Strout’s family if Strout didn’t help him.

Robert Strout told police he was sitting on his porch June 22 or 23 when he saw Ormsby come through the woods with his clothes and bike covered in blood. Ormsby told him he killed Ryan and then said he “killed them all,” including Ryan’s son, Jesse, who was visiting, and 30-year-old neighbor Jason Dehahn, the affidavit said.

Ormsby then told Strout that he had to get rid of Ryan’s truck. Strout followed him as Ormsby disposed of it, the affidavit said. Authorities found the burned truck on June 26 about 15 miles from Ryan’s home.

Strout also told police he drove Ormsby to a bog where Ormsby got out and threw a knife into the water, the affidavit said.
