British murder suspect Neil Entwistle was formally charged with the murders of his wife and daughter in a Framingham courtroom Thursday afternoon.

Entwistle, 27, showed no emotion as his attorney, Elliot Weinstein, entered a not guilty plea to charges Entwistle murdered his wife, Rachel, 27, and 9-month-old daughter, Lillian Rose.

Entwistle was ordered held without bail pending a probable cause hearing on March 15. The trial is not expect to begin for at least a year.

The mother and stepfather of Rachel Entwistle, Priscilla and Joseph Matterazzo, arrived in court around 1:30 p.m. with several friends and family members.

Immediately following the arraignment, a spokesman for Rachel's family said the charges brought little relief.

"Seeing Neil Entwistle standing accused of this awful crime gives us little comfort and only adds to our pain and suffering," Joe Flaherty said. "We never suspected that Neil was anything other than a loving father, a trusted son-in-law and a husband. Neil betrayed our trust in so many different ways that it is almost impossible to describe it."

Investigators believe Neil Entwistle used one of his stepfather's guns to commit the murders, and returned the firearm to their home before flying to England.

"What's most outrageous in our eyes is that he entered our home twice in the course of these crimes, once to take the murder weapon and arm himself and a second time after the murders in an attempt to hide the weapon and perpetrate his crime," Flaherty said.

Weinstein told reporters gathered outside the court after the arraignment that he was concerned that his client would not be able to get a fair trial.

"I don’t know that Mr. Entwistle will ever be able to get a fair trial on these charges. And my concern that he can't get a fair trial is because of what has occurred and the publicity surrounding this event. I am certain that anybody watching this telecast or reading the reporting of today's arraignment has already formed an opinion with respect to Mr. Entwistle's guilt, and that opinion is based upon the reporting, and that opinion is based upon absolutely no facts and absolutely no evidence and that is quite unfortunate," Weinstein said.

Entwistle spent Wednesday night at the Hopkinton Police Department in Massaachusetts after arriving back in the United States on a small government plane. He was handcuffed, shackled and was wearing a bulletproof vest. He was fingerprinted and booked at the police station.

Rachel and Lillian were found shot to death in their Hopkinton home on Jan. 22. Entwistle flew to his native England the same weekend they were killed. An arrest warrant was issued for Entwistle Jan. 15 and he agreed to voluntarily return to the U.S. to face the charges.

The son of a coal miner, Entwistle grew up in Worksop, England. He met the former Rachel Souza, of Kingston, Mass., while both were attending university in England and the couple were married three years ago. The Internet entrepreneur has now had all his online businesses shut down and his personal property in Hopkinton was seized.

Weinstein was appointed to represent Entwistle by the Committee for Public Counsel Services, a state agency that pairs private attorneys with defendants who can't pay. Weinstein has degrees from Trinity College and Boston College. Weinstein has worked on several high-profile cases locally, including serving as defense attorney for one the Anguilo brothers during an organized crime trial.

Middlesex Assistant District Attorney Michael Fabbri will prosecute Entwistle. He has degrees from Northeastern and Framingham State College. Fabbri joined the district attorney's office in 1985. He carries a caseload that includes first-degree murder cases and other serious violent felonies.

Attorneys on both sides of the case are likely to discuss the significant pre-trial publicity the case has generated on both sides of the Atlantic, and whether it will hamper Entwistle's ability to get a fair trial. There were more than 100 members of the media outside the Framingham court before Entwistle's arraignment.

The Entwistle case is expected to cost taxpayers $1 million.
