A British man appeared in court in the US last night charged with murdering his wife and baby.
Neil Entwistle (27) was ordered to be held without bail by the judge at Framingham District Court in Massachusetts.
He is alleged to have shot his American wife Rachel and nine-month old daughter Lillian on January 20, before fleeing to Britain.
Entwistle was told he would appear in court again for a "status" hearing on March 15.
No details of the charges were read out in court, and Entwistle - grim-faced in a zip-up black top - only nodded when he was asked whether he knew what the accusations were.
He has entered a not guilty plea.
A statement on behalf of Mrs Entwistle's mother Priscilla and stepfather Joseph was read outside court by Joe Flaherty, a family friend and former state police commander.
He said: "Seeing Neil Entwistle standing accused of this awful crime gives us little comfort and in fact only adds to our immense pain and suffering."
He said the betrayal to Rachel and Neil's families was "unbearable".
"From what we have learned in the course of the investigation, we are now only coming to realise the level of his deceit," Mr Flaherty said.
"We are astonished and devastated to learn of the hidden life of Neil Entwistle. We never suspected he was anything other than a loving son-in-law, husband and father.
"Neil betrayed our trust in so many different ways that it is almost impossible to describe."
Mr Flaherty said what was "most outrageous" was that Entwistle had allegedly entered the Matterazzo home twice during the course of the crimes he is accused of - once to take a weapon from Mr Matterazzo's collection and again to put it back.
Entwistle's lawyer, Elliot Weinstein, who was appointed to represent him because he cannot afford to hire a private attorney, told reporters: "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 in the publicity surrounding this event.
"I'm going to vigorously, aggressively and successfully defend Mr Entwistle and I'm going to do that in the only arena that counts and that is the court room," he said.
Entwistle agreed to be extradited when he appeared in court in London last Friday, and he was handed over to US marshals at Gatwick Airport on Wednesday.
