He says that she was lonely and invited him in to her flat. This girl was in a committed relationship and if she had been lonely she could have stayed in the pub with her mates.

He says he tried to kiss her! Yeah right! He stopped her from screaming by placing his hand over her mouth for about 20 seconds! Yer Wot! She was a fit young girl who had 43 separate injuries when her body was found. She fought for her life!
