Seems the barbed wire around the sewage treatment works was possibly cut not long before the attack.
"Mr Paxton said: "This barbed wire fence was right on the route Anita walked - it brought Roy Barclay and Anita together, with Roy Barclay in a place he should not have been at the Brantham sewage works.
"Whether cutting that barbed wire or not, or on his way in or out, being seen by Anita who was passing would be the very thing he would not want - he could not risk a picture being taken or Anita making a phone call."
Barbed wire was cut close to where dog walker was found beaten, court hears
