WISCASSET (AP) – A 9-year-old girl who witnessed the fatal shootings of her mother and grandmother in Boothbay Harbor said the weekend tragedy unfolded following an argument outside the grandmother’s summer home.

Details of the shootings surfaced Monday as murder defendant Jon Dilley, 51, of Pittston made his initial appearance in district court amid tight security. Dilley, accused of killing Sarah Murray, 71, and Chevelle “Chellie” Calloway, 41, wore a bulletproof vest as he entered the courthouse.

Dilley’s daughter, Emma, witnessed the shootings Saturday and was quoted in a state police affidavit as saying she saw her father remove a handgun from the trunk of his car following a family argument outside Murray’s home next to the Coast Guard Station at McKown Point.

The girl said Murray and Calloway ran inside the house and locked the door, but Dilley shot through a glass sliding door and entered the home through the broken glass.

Calloway’s body was found inside the house and Murray’s in the yard.

Emma and her 6-year-old brother ran to the Coast Guard station after the shootings. An 18-year-old daughter was not at the shooting scene. The younger children were placed with godparents who arrived from out-of-state.

The affidavit quoted Dilley as admitting to police that he shot the two women and then telling an officer that the semiautomatic handgun was in the trunk of the car. Police opened the trunk and found a Glock handgun.

The 14-page court document did not spell out a motive for the killings.

It states Boothbay Harbor Police Officer Ted Raedel drove to the house after a dispatcher received reports of shots being fired. As Raedel approached the house, Darren Graves, a wrecker driver who monitors local police radio, also arrived and offered his assistance, the affidavit says.

A man walked out of the house and Raedel ordered him to the ground.

“As Officer Raedel held the subject at gunpoint Graves handcuffed the subject,” the affidavit says. Raedel then asked the man, who was identified as Dilley, questions about the shootings.

Dilley worked as a telecommunications specialist in Portland; his wife was a social studies teacher at Cony High School in Augusta.

Dilley entered no plea at Monday’s hearing. Bail was not set and Dilley remained in Lincoln County Jail in Wiscasset pending further court action.
