Didcot triple murder: Detectives hunting Jed Allen discover his body in wooded area
Mr Ward said 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.
Allen, a fan of the blade-wielding X-Men comic-book anti-hero Wolverine, wore a distinctive spider tattoo on his left hand.
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".
The 21-year-old, who is suspected of murdering three members of his family, had a troubled family life and had struggled with his mothers' alcoholism, it has been claimed.
The bodies of his half sister, Derin, six, his mother, Janet Jordon, 48 and her partner, Philip Howard were found at the family home in Didcot, Oxfordshire, on Saturday evening. They are believed to have been stabbed.
As a major manhunt involving 120 officers took place today, a former girlfriend wrote on Facebook that he had "always had family issues and anger problems".
The family's former landlady shed led light on Mr Allen's difficult upbringing.
And she claimed that two of Ms Jordon's other children were put up for adoption as a result of her alcoholism.
Jane Ilott, a former mayoress of Kidlington, who rented a property to the Jordon family, told the Telegraph: "She had a problem with drink. She wasn't an aggressive drunk but just wasn't herself.
"Jed would often come round and say to me 'Mummy has been drinking but don't tell her I told you because I will get in trouble'.
"One time my son had to go in through the window because we were at the door and could see her but she wasn't opening it.
"Another time we found her fallen on the patio alongside her baby and we were worried that she had dropped it."
Mrs Ilott said that when the council stopped paying Ms Jordon's rent, she let her live rent-free until she found somewhere else.
She added: "Jed was never unkind, always polite but sometimes tense. He was smiley, tall and very handsome.
"It must have impacted on him when two of Jan's children were adopted.
"He would have had a very difficult time back then. He did seem on edge and a little bit stressed."
Ms Jordon began to rent from the Ilotts in August 2004, moving to another of their properties in October 2005 where they stayed until 2006.
An undated correspondence between Mrs Jordon's mother, Heather Jordon, and Mrs Ilott, seen by the Daily Telegraph, apologises for an incident involving alcohol.
"An apology to you all for Jan's behaviour all round on Tuesday afternoon. I am absolutely gobsmacked by her and ashamed," it says.
"She was way out of order making a spectacle of herself.
"I am so sorry for that particularly as your grandchildren were there."
Margaret Davies from Didcot town council, for which Mr Allen worked as an apprentice gardener, described him as calm and normal.
She said: "He's worked for a couple of years for Didcot Town Council and has been calm, has been working in the parks and has been fine. Studying at Abingdon and Witney College - a normal person."
Meanwhile, a cousin of Mr Allen has urged him to give himself up to police.
Tyler Clarke told The Sun: "No-one can believe what has happened.
"The first thing I knew about it was when I saw it on the news. We just want to know why."
"If we could send a message to Jed it would be, 'Give yourself up'."
Mr Allen's Instagram profile, which is named Mr Meat Tank, reveals his interest in bodybuilding and comic book characters.
He attended Marlborough School in Woodstock and Abingdon and Witney College, where he studied for an NVQ Level 1 and 2 in horticulture.
Oxford University Parks, which was closed to the public on Sunday as police combed the 70-acre grounds, was reopened as the search area widened on Monday.
Speaking at a press briefing, Detective Superintendent Chris Ward from Thames Valley Police warned the public not to approach the suspect, describing the incident as a "tragic and sad event".
Mr Allen has a distinctive spider tattoo on his left hand and is described as white and of large build. Det Supt Ward emphasised the need to find him as soon as possible.
It is understood that the school attended by six-year-old Derin will be open on Monday for friends and parents to meet to support one another.
