ABC News Exclusive: Entwistle Posts Lewd Photo Online

July 18, 2008— -- A pornographic photograph posted online by convicted wife and baby-killer Neil Entwistle was kept under wraps -- until now. The 30-year-old computer engineer from Worksop, England who was given two life sentences last month for murdering his American wife Rachel and 9-month-old daughter Lillian managed to persuade a Boston judge that this picture was irrelevant to the case against him. Prosecutors, however, said it showed that his outward appearance was a sham and he was living a secret life of lies and sexual deviance. The photo was never shown in court.

Entwistle posted what appeared to be a self-portrait taken in the garden of his parents-in-law house. The picture, obtained exclusively by ABC News, was posted on a Web site used for soliciting sex called AdultFriendFinder.com and shows Entwistle aroused in a lounge chair. Attached to the picture was a caption written by Entwistle which said, "I am looking for one on one discrete (sic) relationships with American ladies."

His wife had no idea that he was obsessed with Internet sex and she could not access their home computer because of special passwords.

Entwistle, who met Rachel at York University where she had won a 12-month scholarship, persuaded his wife that they should move to America. He blamed his northern England accent and the fact that his dad was a coal miner for his faltering career.

Within a few months, in January 2006, he'd killed both his wife and their baby daughter in an execution-style shooting.

Entwistle was given two life sentences and is spending 23 hours a day in an isolated prison cell just outside of Boston. Entwistle's parents claim that it was his wife, Rachel, who killed her own baby and then committed suicide. But evidence in court showed that Entwistle's DNA was on the gun's grip and his wife Rachel's DNA was in the muzzle.

Crimes 'That Defy Comprehension'

What caused a young, apparently happily married British man to shoot his 27-year-old American wife and their daughter at point-blank range and leave them for dead on a blood-soaked bed as he fled to England?

People on both sides of the Atlantic have been pondering that question for two years now, ever since the stunning arrest of Entwistle in February 2006.

Police had been on Entwistle's trail ever since the bodies of Rachel and Lillian Entwistle were found Jan. 22, 2006, with their arms intertwined in the master bedroom of their spacious colonial home on a quiet cul-de-sac in Hopkinton, Mass.

The court sentenced Entwistle Thursday to two concurrent life terms for what Judge Diane Kottmyer called crimes "that defy comprehension."

Kottmyer went on to castigate Entwistle for his actions "because they involve the planned and deliberate murders of the defendant's wife and 9-month-old child in violation of bonds that we recognize as central to our identity as human beings -- those of husband and wife, and parent and child."

Since his arrest, Entwistle has maintained a sphinxlike demeanor -- for the most part remaining expressionless through his arraignment, incarceration and conviction.

So it was fascinating for members of the media to get a glimpse into the mind of a killer as evidence from the trial was put on display in Courtroom 430.

That prosecution's evidence included a spiral notebook seized from Entwistle when he was arrested in February 2006. In the pages of the book, there is a draft letter in which Entwistle pretends to be a "close friend" and pitches a proposal to sell his story to the highest bidder.

"What's of interest to us is what price you would be willing to pay for the exclusive rights to the full story. … We are leaving it open to the highest bidder," wrote Entwistle. And, he added, there would be enough material to last "a week."

The prosecution has long argued that Entwistle killed his wife and child because this suburban dad was dissatisfied with his sex life and swimming in debt. In closing arguments, assistant district attorney Michael Fabbri said that Entwistle had "reached a tipping point."

Internet Sex Searches

Evidence released in June showed pages and pages of Internet sex searches and e-mail correspondence with women in which the supposedly happily married Entwistle indicated his eagerness to have sex with strangers.

There was also a file folder of collection notices addressed to Rachel and Neil Entwistle from the time period in which they lived in England.

Perhaps among the more intriguing evidence items was a letter found in Neil Entwistle's backpack. At first glance, it seems like a love letter -- an impassioned description of a love that ended too soon.

But given that the killer was intent on selling his story, it could be that the writings are nothing more than a fantasy first chapter in a murderer's memoir.

Entwistle wrote, "As a husband I could never dream for more. She was my soul mate and my very best friend. The love we shared knew no bounds, a love that brought on both comfort and excitement. ... We would model our love on four roses, red for passion, yellow for fidelity and white for pure love. The combination of these roses is the orange and that is what we are to each other."

Entwistle went on to describe Rachel in glowing terms and said "everyone who has been in her company will have been touched by her kindness, her love and her energy. And that is what I hope people will remember most."

An 'Eternity of Emptiness'

In a victim impact statement in the Massachusetts courtroom Thursday, Rachel Entwistle's family said what they would remember most was a beautiful woman and a "perfect mother."

Priscilla Matterazzo, Rachel's mother, told a hushed courtroom that her family had been sentenced to an "eternity of emptiness." Matterrazzo went on to describe her family's pain."Suffering does not begin to describe what we have been enduring without our beloved Rachel and Lillian," she said.

She also lashed out at Entwistle, calling him "low and despicable" for allowing his defense counsel to accuse Rachel of a murder-suicide in their closing arguments.

After Kottmyer announced Entwistle's sentence, she added one final ruling: Entwistle is "not to profit in any way from the sale of his book or otherwise to any media outlet."

Entwistle came into court Thursday looking every inch the computer engineer he used to be. Dressed in a suit and tie, Entwistle glanced briefly at his family, which sat huddled in the front row.

Entwistle left the courthouse in an orange jumpsuit, with shackles chained to his wrists and legs -- preparing to spend the rest of his life behind bars.
