Detectives hunting a man after his young sister, mother and her partner were found stabbed to death at their home, have discovered a body in a wooded area in Oxford, Thames Valley Police said.
Remains believed to be those of triple killing suspect Jed Allen, who was an ardent fan of comic book superhero Wolverine and had a distinctive spider tattoo on his left hand, were found by a member of the public on Monday.

Armed officers were scouring Didcot in Oxfordshire after the bodies of Philip Howard, 44, Janet Jordon, 48, and daughter Derin, six, were discovered in a house in Vicarage Road just after 8.20pm on Saturday.
Detective Superintendent Chris Ward, head of Thames Valley Police's major crime unit, told reporters that though the body found in Marston Road, Oxford, had not been formally identified, he was satisfied it was Jed Allen.
He said: "The body was discovered in an area of woodland accessible by two members of the public. This area had not previously been searched by police.
"Our investigation continues but we are not looking for anyone else in connection with the murders."
Mr Ward, who said an inquest would be carried out in due course, added: "My condolences go out to the families and loved ones. We have specially trained officers with the families and will continue to support them at this extremely difficult time.
"I would like to thank the public for all their help during this investigation, as well as their patience while we have been carrying out searches."
Detectives had earlier released images of Allen which seem to show him buying a large bottle of water in a shop just hours before the three victims were found stabbed to death at their home.
The heavily-built 21-year-old was caught on CCTV in WHSmith at Oxford railway station, ten miles from the Didcot crime scene where detectives had found what they believe is the murder weapon.
More than 100 police, including specialist search officers, had been deploy to search Oxford University Parks where Allen worked as a groundsman.
Detectives believed that Allen had arrived in Oxford by train from Didcot at 5.45pm on Saturday.
Derin's young friends struggled to come to terms with her killing.
Parents with their young children flocked to All Saints primary school in Didcot, where she was a Year One pupil, to leave flowers and teddy bears.
Some could be seen crying outside the gates, visibly distraught at such terrible news.
A community centre next to the school was opened to give local people a place where they could grieve together.
John Myers, the headteacher of All Saints, said the reaction had been "devastation, shock, sadness".
He said: "It's just a combination of so many emotions, it's such a terrible tragedy.
"Anybody's life is precious and to lose parents and particularly a young girl in such a dreadful manner is truly awful."
Mr Myers described Derin as "beautiful, gentle, quiet, smiley, happy, precious, a lovely girl".
He said they had seemed like "a perfectly normal, happy family".
