i think hes a suspect because he killed himself after the incident of Mark haynes. I don't think he killed him because he was a good mate of Mark.
I dont thik it was him because he seemed like he wouldnt hurt someone in a killing way. i think it could of been him because he was a boxer and he could of just had a punch on with mark
i think he did do it because he was aggressive and almost looking to say no to any of the questions they had to ask him. i dont think it was him because he might of been annoyed that everyone kept asking him about it and he might of just been sick of everyone saying he might of done it
