Briton Neil Entwistle spent the month before his wife and daughter were murdered looking online for sexual encounters, a court has heard.
Entwistle used his credit card to pay £10 for a month’s membership on the Adult Friend Finder site, a “sex and swinger personals community”, which expired on January 21, 2006 – the day he fled to England after the killings.
The 29-year-old former IT worker denies killing his 27-year-old wife Rachel, a former teacher at a Worcestershire school, and nine-month-old daughter Lillian Rose at their new home in Hopkinton, Massachusetts.
On his Adult Friend Finder profile, Entwistle wrote: “I am an Englishman just moved over to the US. I am looking for 1-on-1 discrete (sic) relationships with American ladies and always aim to make all experiences ones to remember.
“I’m looking to meet American women of all ages.
“I need to confirm what friends have told me that you are much better in bed than the women over the ocean, as from there.
“We both want the same thing so there is little point dragging it out here.”
Detective Lawrence James, a computer specialist, told the Middlesex County Superior Court in Woburn, Massachusetts, the profile was recovered from the internet history of Entwistle’s laptop.
Entwistle paid 19.95 dollars (about £10) for the month’s membership.
Mr James also told the jury of eight men and eight women that someone read emails associated with Entwistle’s username “ent” at 12.30pm on January 20 – the same day US prosecutors believe Entwistle murdered his wife and baby daughter, and less than an hour-and-a-half after Entwistle claims he discovered their bodies.
Entwistle’s parents Yvonne and Cliff, from Kilton, Worksop, wiped tears from their eyes at the front of the public gallery as Mr James read out Entwistle’s profile.
Their son used the username “srpub” on the sex website, the court heard.
US prosecutors have said Entwistle had a secret life in which he trawled the internet for escorts and looked at websites about bankruptcy, killing and suicide before shooting his family.
Mr James told the court Entwistle’s username was also used to search for the “best” way to kill someone four days before the deaths.
He showed the jury a diagram from Entwistle’s laptop which showed the major human arteries and “strike points” in the chest.
The diagram, found after an internet search for “how to kill with a knife”, was accessed shortly after 11.30pm on January 16, Mr James said.
A person using Entwistle’s “ent” username searched the internet for “knife in neck kill” shortly after 4.15pm on January 17.
On the same day, the user searched for “quick suicide method”.
The jury has heard a post-mortem found Mrs Entwistle – who taught at St Augustine’s Catholic High School in Redditch, Worcestershire, between 2002 and 2005 – was shot in the forehead at close range. Lillian was killed with a bullet which passed through her abdomen and lodged above her mother’s left breast as she cradled her in the four-poster bed in the master bedroom of their home.
Entwistle faces life in prison without parole if convicted of the double murder.
Later, Dr William Zane told the court the post-mortem revealed Rachel died from a gunshot wound above the hairline – an injury which not noticed at the scene.
She was also shot in the left of her chest, but this did not damage vital organs, he said.
A photograph of her head, taken during the post-mortem, was shown to the jury, but not the public gallery.
Baby Lillian, 2ft 4in tall and 21.5lb (9.75kg), took “a minute or minutes” to die after being shot through her abdomen, Dr Zane said.
