After an unsuccessful attempt at questioning the victim, who told him she did not want to get involved, Doucette threatened her and demanded that she have sex with him or he would harm his girlfriend, according to police.
The woman said she gave in to his demands for sex and told police she did not report the incident right away because she was in fear for her own life.
Terrell Harris, a spokesman for the Executive Office of Public Safety, which oversees the Parole Board, said the new charge will trigger a request for revocation of Doucette's parole.
If the board finds that Doucette did violate his parole, he would be returned to prison to resume serving his life sentence in the murder and in two violent home invasions he committed while out on bail in the murder case.
He would not be eligible to seek parole for at least five years, Harris said.
Family members of Bufalino said Doucette never should have been back on the street, especially since he continued to maintain that the shooting was an accident — though he shot Bufalino twice.
