Knox book to aid Kerchers?
Stephanie Kercher, Meredith's sister, said they would first wait for the court's written explanation of Monday's verdict.
"Once we've got the reasons behind the decisions for this one, then we can understand why they have been acquitted of it and work toward finding those who are responsible," she told a news conference in Perugia as Knox waited at a Rome airport for a flight to London and then on to Seattle.
"That's the biggest disappointment, not knowing still and knowing that there is someone or people out there who have done this," she said.
The acquittal of Knox and Sollecito leaves Rudy Guede, an Ivorian drifter and drug dealer, as the only person convicted of the killing which investigators believe was committed by more than one person.
Guede was jailed in 2009 and is serving a 16-year sentence for his role in the murder.
Kercher's body, with more than 40 wounds and a deep gash in her throat, was found in 2007 in the apartment she shared with U.S. student Knox in the Umbrian hill town of Perugia, where both were studying.
DNA evidence used to convict Knox and Sollecito was discredited by experts but questions remain over who, other than Guede, was involved in the attack in which Kercher was pinned down and stabbed.
"Of course if those released yesterday are not the guilty party, we are now obviously left wondering who is the other person or people.
"For us it feels very much like being back to square one. And the search goes on to find out what truly happened," he said.
However, he said that the family "accepts the decision that was handed down and respects the court and the Italian justice system."
He was in the Italian courtroom with his mother Arline and sister Stephanie on Monday night when the appeals verdict was read out.

Stephanie Kercher added that the family would not be able to forgive anyone until the truth came out.
"We didn't want people put away for a crime they didn't commit," she said. "It may be a case of waiting another year now to get the truth. We have to leave that to the police ... and the courts."
Apathetic Italians moved to anger by verdict
British tabloids summed up the feelings of the two families neatly: "Foxy's free. Meredith family agony as Amanda cleared," the Daily Mirror read.
"Foxy" is the nickname that the British tabloids have given to Knox.
The Daily Mail pushed it even further: "Weeping Foxy is freed to make a fortune" — alleging that Knox would be paid by U.S. media to tell her life story.
Prosecutors say they will appeal against the acquittal verdict, which they say has left many issues relating to the murder unclear.
"I wasn't surprised but I was disturbed by it," prosecutor Manuela Comodi told reporters.
"It seems to me that all anyone's talked about, even before the trial began, was how the two accused were going to be acquitted."
The major players in the Amanda Knox trial
The Kerchers have maintained a low profile throughout the trial, while Knox's supporters ran a well-organized campaign to convince the wider public of Knox's innocence.
The victim's family has refrained from any criticism of Knox or Sollecito but has said repeatedly that Meredith has been forgotten in the media frenzy over the young American.
"What happened to my daughter Meredith is every mother's nightmare," her Indian-born mother Arline said.
"We're still absorbing it. You think you've come to a decision and now it's been overturned."
British Prime Minister David Cameron urged people not to forget Meredith Kercher's family.
"Those parents ... had an explanation for what had happened to their wonderful daughter, and that explanation isn't there ... I think everyone should be thinking about them and how they feel," he told ITV.
