BANGOR — Lloyd Franklin Millett, who was serving a 70-year sentence for killing two women, died Tuesday night at Eastern Maine Medical Center, the Maine Department of Corrections said Wednesday morning.

Millett, 51, died after being severely beaten May 24 by at least one other inmate at the Maine State Prison in Warren. Millett was serving a life sentence for murdering two women, Terrie Lizotte, 39, of Canton and Rachelle Anne Williams, 33, of Gorham, N.H., in 1995. He committed the murders over a weekend while a farmhand in Turner.

Maine Department of Public Safety spokesman Stephen McCausland said a team of detectives led by Sgt. Erik Baker has been working the case since the assault but has yet to press any charges. McCausland said the detectives’ report would be forwarded to the Knox County district attorney, who will decide how to move forward with the case.

Williams’ body was found Nov. 6, 1995, in a field near the Ramada Inn in Lewiston, where she was attending a business meeting. She was last seen alive in a hotel lounge but disappeared after she left to go to a restroom and never returned. Williams’ raped and strangled body was found the next day.

Millett met his other victim, Lizotte, at a Turner nightclub on Nov. 3, 1995. Lizotte’s body was found in the closet of the trailer where Millett lived on a farm in Turner.

Lizotte’s body was found by Millett’s ex-girlfriend, who recently had moved out of his home but returned to retrieve her belongings.

Millett, a native of Rumford, pleaded guilty to both murders at one point in the case. He later filed a motion to reverse his pleas, but the motion was denied by the court. He was sentenced to 70 years in prison for Lizotte’s murder and a concurrent life sentence for killing Williams.

Millett had a lengthy criminal record before the murders, including a 1991 rape conviction for which he was sentenced to eight years in prison with four years suspended.
