Armed police officers are scouring Didcot, Oxfordshire, and its surrounding areas, after the bodies of Philip Howard, 44, Janet Jordon, 48, and daughter Derin were discovered in a house in Vicarage Road just after 8.20pm on Saturday, following a call from a member of the public.
More than 100 officers are also searching Oxford University Parks where Allen worked as a groundsman.
Police also revealed they have found what they believe is the murder weapon at the crime scene.
Detective Superintendent Chris Ward, the head of Thames Valley Police's major crime unit, said they believe Jed arrived in Oxford by train from Didcot at 5.45pm on Saturday.
Det Supt Ward said: “Jed is wearing a red or maroon shirt, a dark hooded jacket with a white trim on the zip, blue jeans and black shoes.
“After visiting WH Smith, we believe that Jed then walked to Oxford University Parks.”

“I can confirm that what we believe to be the murder weapon was found at the scene of the murder in Vicarage Road, Didcot.”
He continued: “If anyone is harbouring Jed Allen then you need to know that this is a serious offence and we would ask you to contact us immediately.”
