Edward F. Boyle, a former Groton resident, is set to be released today from Osborn Correctional Institute in Somers after serving 60 months in jail for sexually assaulting a 14-year-old girl five years ago.

At the time of the assault, Boyle had been released from prison after serving time for the 1980 manslaughter and rape of a young woman from Coventry, whose family protested his imminent release on the later charges on Monday.

Boyle, who is now 48, has completed his prison sentence after pleading guilty to two counts of second-degree sexual assault for the November 2004 incident in Groton. Second-degree sexual assault involves intercourse between someone 13 to 16 years of age and someone at least three years older. There was no violence alleged in that incident.

Boyle's special parole conditions include living in a halfway house, undergoing treatment and being monitored by a GPS device.

But those parole conditions are not enough for the family of Louise M. Scott, whom he strangled while raping in Coventry in 1980.

"It's hard to think a halfway house, a GPS, or any kind of treatment is going to protect the women of Connecticut from this kind of predator," said Timothy Scott, brother of Louise Scott. "We made a promise to our sister that we would do anything we could to keep him incarcerated."

Scott said his family would like to see Boyle behind bars for many more years.

When Boyle was sentenced in 2006 for the assault on the teenager, a New London Superior Court judge ordered that he serve 90 months of special probation after his incarceration. While out on parole, Boyle will have to re-register as a sex offender.

Brian Garnett, a Department of Correction spokesman, said Boyle will be under "intensive parole supervision." Boyle will initially be living in a halfway house. Garnett would not say where the halfway house is, other than that it is in state.

The Board of Pardons and Parole set the conditions of the parole, which include no contact with the Groton victim or minors.

Timothy Scott said that during Boyle's parole hearing in the early 1990s, Boyle had told the board he had found God and was reformed with the help of treatment he received in prison.

In May 1980, Louise M. Scott, a 20-year-old bowling alley worker, thought she was following Boyle to a party when he took her out of her car near the Skungamaug River and strangled her while raping her. Boyle dumped her body in the river, and the case went unsolved for more than two years.

While already incarcerated for raping a 62-year-old woman from Manchester, Boyle confessed to killing Scott. For that crime he was sentenced to 10 years in prison for manslaughter and five years for first-degree sexual assault and released from prison in 1999.

According to reports in The Day in 2004 and 2006, the sexual assault of the Groton teen occurred after Boyle had befriended her family. The family told police, according to an arrest warrant, that they had Boyle over for dinner because they were trying to be good neighbors after he was up front about his criminal history.

They had drinks and played darts before Boyle asked the teenager's mother to walk him home at 12:30 a.m. The mother refused but said her daughter could walk Boyle home as long as she returned immediately, the warrant said.

After 20 minutes, the family went looking for her, according to the court documents. The lights were off in Boyle's one-room apartment but a window was open. The girl's sister heard Boyle say, "Someone is coming." The sister reached through the window to turn on a light.

She said she found her sister standing near Boyle's bed in sweatpants and a tank top and Boyle sitting on the bed with his shirt off, family members told police.

The teenager initially said she and Boyle "hugged and kissed" one night, but later admitted that on several occasions from June 2004 to October 2004 they had sex, according to the warrant.

Boyle told police that he did not sexually assault the girl. He pleaded guilty under the Alfred Doctrine, which means he did not admit guilt but conceded the state had enough evidence for a conviction. A message left Monday for John P. Gravalec-Pannone, the prosecutor in the case, was not returned.
