An autopsy on the body of Lawrence J. Lewis, 68, was conducted at the state medical examiner’s office on Wednesday, Department of Public Safety spokesman Stephen McCausland said.

“Additional testing will be done before they arrive at a final conclusion,” McCausland said Wednesday afternoon.

Lewis’ body was found in his Macwahoc Road home while authorities were engaged in a standoff with Bruce King, 59, on Interstate 95 near Lincoln. That incident concluded with King fatally shooting himself in the head with a rifle.

McCausland said King told police during the standoff on the interstate that he was responsible for Lewis’ death and that Lewis’ body was inside the Molunkus home.

According to Bangor Daily News archives, Lewis is a lifelong registrant of the state’s sex offender registry. He was convicted in 1996 of sexually assaulting a 9-year-old boy who lived in the same household.

Police also have confirmed the identity of the woman driving the U-Haul truck as 43-year-old Lynda Fogg of Mattawamkeag, King’s wife, McCausland said. She has also been known recently as Lynda Gordon, he added.

The U-Haul truck Fogg was driving, in which King was a passenger, was pulled over around 4 p.m. Monday near mile marker 225 in the southbound lanes of I-95, and he held a .30-30 caliber rifle to his head during the standoff as police attempted to talk with him.

McCausland said Fogg has been cooperative with police during numerous interviews.

King and Lewis have known each other for quite some time, the state police spokesman said, and Fogg and King had been married since March 1.

The couple had been staying with Lewis since last fall and moved out recently, staying at motels and with relatives, McCausland said.
