BOSTON -- Court documents released Monday shed new light on the double murder of Rachel and Lillian Entwistle in their Hopkinton home. Rachel Entwistle's husband, Neil, has been arrested in England and will be charged with murder when he returns to the United States.

NewsCenter 5's Janet Wu reported that court documents paint a dark picture of Neil Entwistle.

Court documents unsealed over the objections of Middlesex District Attorney Martha Coakley show Neil Entwistle made conflicting and inconsistent statements to his family and to investigators in the days after his wife and daughter were found shot to death in their home. The documents show Entwistle told his parents he called police after discovering Rachel and Lillian's bodies, but there is no evidence to support that.

The documents also say Neil Entwistle went up to the bedroom and saw blood on his daughter and saw that both his wife and daughter had been shot. Investigators found, however, that the baby's face was covered with a pillow and there was no immediate, visible evidence that either Rachel or Lillian Entwistle had been shot. The shots were later confirmed by an autopsy.

The documents also revealed that Neil Entwistle was extremely secretive toward his in-laws and wife. The Matterazzos were led to believe Neil Entwistle had some type of secret government job in England that he could not talk about. Documents say Rachel asked Neil Entwistle questions about their finances, but he would not divulge any information, which caused some conflict between the couple. Rachel told her mother that their money apparently had been tied up in offshore accounts, although Neil Entwistle would not talk about it.

Meanwhile, court documents say, in the four days prior to Rachel and Lillian Entwistle's deaths, Neil Entwistle's computers show he visited Web sites like Adult Friend Finder and conducted Internet searches for escort services, including Eye Candy Entertainment, Exotic Express, Sweet Temptations and Blonde Beauties Escort Service.

Investigators said Neil Entwistle also surfed Web sites that described how to kill people. Neil Entwistle typed in Internet searches regarding how to kill yourself, suicide, how to kill someone with a knife and euthanasia.

Despite mounting debts, the Entwistles purchased $6,000 worth of new furniture and mattresses just days before the deaths.

The court documents also revealed that Neil Entwistle was in such a hurry to leave the United States, that even though he had purchased a ticket to fly to London for Saturday afternoon, he bought a second, one-way ticket at the last minute so he could leave six hours earlier.

Officials expect Neil Entwistle to be returned to Massachusetts this week, perhaps as early as Wednesday.
