A British man accused of murdering his American wife and baby at their home in Massachusetts will be arraigned in a US court today.
Neil Entwistle (27) is on his way to America on a private flight in the custody of US Marshals.
Joan Kenney, spokeswoman for the Massachusetts Supreme Judicial Court, said he would appear at Framingham District Court at 2pm, where he will be arraigned on two charges of first-degree murder.
He is accused of shooting his wife Rachel and nine-month-old daughter Lillian dead on January 20, before flying to Britain to stay with his parents in Worksop, Nottinghamshire.
Entwistle agreed to be extradited during a hearing at Bow Street Magistrates' Court, in central London, last Friday after being arrested in the city over the deaths of his wife Rachel and nine-month-old daughter Lillian.
Mrs Entwistle, who taught at a Worcestershire school, and Lillian were discovered in a bed in the couple's home in Hopkinton, Massachusetts, on January 22.
Court papers released on Tuesday revealed Entwistle searched the internet for information on how to kill and commit suicide days before their deaths.
He also looked up escort services and other websites offering help finding sexual partners in the Boston and Worcester areas of Massachusetts, according to the search warrant documents.
Prosecutors said last week that they believed the unemployed computer programmer killed his wife and daughter after accumulating tens of thousands of dollars in debt.
Entwistle has been assigned a lawyer by the Committee for Public Counsel Services, the body in Massachusetts which provides representation for those who cannot afford to hire a private attorney.
His lawyer, Elliot Weinstein said he was already very concerned that Entwistle would not get a fair trial because of the high media profile.
