What evidence was removed from the home of the late Lawrence J. Lewis, 68, is not being released, and the cause of his death is still pending, Maine Department of Public Safety spokesman Stephen McCausland said Thursday morning. The medical examiner has determined it was a homicide.

“I do not expect, at this point, any new information to be released,” McCausland said. “This is going to be a lengthy and complicated investigation.”

Lewis’ body was taken to the medical examiner’s office in Augusta for an autopsy, which has been delayed by the need for additional testing.

“We await the final conclusions from the medical examiner’s office [and] additional interviews to be completed,” McCausland said. “I don’t expect any additional information to be released this week.”

Bruce Heal, 59, who also was known as Bruce King and other aliases, created a four-hour standoff with police Monday night that ended when he used a .30-30 caliber rifle to take his own life.

During the standoff that closed I-95, “Heal told Penobscot deputies that he was responsible for Lewis’ death and that Lewis’ body was hidden inside his house in Molunkus,” McCausland said in a Wednesday release.

Police went to Lewis’ home and found his body inside.

Lewis was on the state’s sex offender registry for life after having been convicted in 1996 of sexually assaulting a 9-year-old boy who lived in the same household, according to Bangor Daily News archives.

Heal married Lynda Fogg, 43, of Mattawamkeag on March 1. The couple moved in with Lewis in the fall and recently moved out and had been staying at motels and with relatives, McCausland said.

She was driving him south in a rented U-Haul truck when Penobscot County deputies stopped them on Monday just south of Lincoln.

Fogg, who also has an alias of Lynda Gordon, got away from the vehicle and has been cooperative with investigators, McCausland said.
