Thanks Alyce.
I think there are two pieces of evidence that might tip this into guilty. One is the fibres from the hoodie being inside his coat. The other is being at Tanner's Brook which is where the clothes were dumped, and not saying he went there in his first police interview. Someone would have had to have been following him about, but he was carrying a bag. A third and fourth might be Lucy asking to see him and the claimed pregnancy giving him motive, and him just happening to be sick from work but also out and about at Tesco that morning.
Problem is Lucy didn't create her new Facebook account until the evening before, which was when she messaged him about meeting. He was already off sick and ordering new trainers. Unless it was him that asked to meet her.
