The husband of a Midland teacher who was shot dead with her daughter at their United States home has returned to Britain, it was claimed last night.
Neil Entwistle, aged 27, vanished from the home in Hopkinton, Massachusetts, he shared with wife Rachel, 27, and nine-month-old Lillian when their bodies were found on Sunday night.
American-born Mrs Entwistle - who taught at a school in Redditch, Worcestershire, until last year - had been shot in the head and Lillian in the body.
Mr Entwistle, a Briton, has not been labelled a suspect but US authorities said he remained a "person of interest" and confirmed he had been tracked to a location "out of the country" and had spoken to US police.
As reports emerged last night that he may have been involved in get-rich-quick pyramid schemes, the local District Attorney's office in the US said progress in the case meant they were "slowly but surely" piecing together the puzzle surrounding what happened.
But officials said there was not enough evidence suggesting Mr Entwistle was involved in the murders to arrest him.
The Boston TV news channel CBS4 reported it has learned from two independent sources that Mr Entwistle was on a passenger list for a flight from Boston to London on Friday. His car was found at Logan International Airport, Boston.
On the couple's website, a message from "Matt" in the UK, who said he was Mr Entwistle's cousin, said: "As far as I know his dad collected him as they live in England and he knows no one over there (in America).
"Neil's home is England, he doesn't know anyone over there as they just moved over there 'to make a better life'."
Mr Entwistle's father, Cliff, is a coal miner and a Labour councillor for Worksop East on Bassetlaw District Council.
His father's colleagues at Bassetlaw District Council said yesterday afternoon they had had no contact with the Entwistle family since news of the double murder.
Officers from Nottinghamshire Police were stationed outside the family home in Coleridge Road, but maintained they have not been asked to attend the address by US police.
The couple met through a rowing club while Mr Entwistle studied electronic engineering with business management at the University of York.
They married in 2003 and moved to the United States shortly after Lillian's birth.
The couple had their own web-site and yesterday it was flooded with tributes from pupils from St Augustine's Catholic High School in Hunt End, Redditch, Worcestershire, where Mrs Entwistle worked for several years.
Hev Williams paid tribute to a "lovely woman with not a bad bone in her body", while Laura Mogg wrote: "She was my theatre studies teacher for three years and she was absolutely wonderful."
Adam Burgess said: "She was an awesome teacher and she really helped me get good grades but above all she was one of the nicest people ever."
Scott Newton said Mrs Entwistle had made an impact on him and everyone she met "with her positive attitude and enlightening smile".
To Andrew O'Neill she was the "best teacher I ever had".
"You looked after me when I broke my collar bone snowboarding when you could have been out enjoying yourself," he said.
Other entries are apparently from complete strangers moved by the story to send their condolences.
It was also claimed last night that Mr Entwistle ran a website which appeared to be "get-rich-quick pyramid schemes" and that a seller - reported to be the Entwistles - on the internet auction site eBay had also received numerous complaints, with two users referring to a Rachel Entwistle in their messages.
