American police investigating the murders of Briton Neil Entwistle's wife and baby do not expect him to attend their funeral, authorities said last night.

The funeral takes place today of the former Midland teacher and her daughter who were found shot dead at their home in the United States.

Rachel Entwistle, aged 27, who used to teach at a school in Redditch, Worcestershire, and her nine-month-old daughter Lillian will be buried in Plymouth, Massachusetts.

They were discovered lying side by side under a pile of blankets in a bedroom at the family home in the quiet suburb of Hopkinton last Sunday.

Last night Mrs Entwistle's husband, Neil, left his parents' house in Nottinghamshire refusing to answer questions from reporters.

Mr Entwistle, aged 27, described as a "person of interest" by US detectives investigating the double murder, was driven from the property in Worksop by his father Clifford. His mother Yvonne was also in the car.

Chief Inspector Matthew McFarlane, of Nottinghamshire Police, who was at the house, refused to say whether the Entwistle family was heading to America or was expected to return.

Mr Entwistle, an unemployed computer technician, is thought to have returned to the UK before the grim discovery was made.

He has not been labelled a suspect by police but was taken voluntarily from the family home in Kilton, Worksop, to meet US officials probing the killings.

The Boston Globe later reported that Mr Entwistle chose not to talk to investigators after receiving legal advice ahead of the scheduled meeting at the American Embassy in London.

A spokeswoman at the Embassy said she was unable to comment on Mr Entwistle's destination.

Forensic evidence showed Mrs Entwistle and her daughter had died at some point between Friday morning and last Saturday night.
