WISCASSET (AP) – Over defense objections, a judge on Friday ordered a preliminary psychological evaluation for a Pittston man accused of killing his estranged wife and mother.

No date was set for the examination of Jon Dilley, 51, who is charged with two counts of murder in the Aug. 21 shooting deaths of Chevelle “Chellie” Calloway, 41, and Sarah Murray, 71, at Murray’s vacation home in Boothbay Harbor.

Dilley, according to a police affidavit, told officers at the scene that he shot the two women and he directed police to a gun in the trunk of his car.

Defense counsel Jonathon Hull said his opposition to the evaluation was based on Dilley’s Fifth Amendment rights against making statements that might incriminate him.

“During the course of the evaluation he may be asked questions that he has a right not to answer,” Hull said.

Dilley was being held at the York County Jail pending a bail hearing next month in District Court.
