An Ipswich prostitute who had sex with Steve Wright after the fifth victim was found thinks that her life was saved because they were disturbed by an unexpected noise.
Tracy Russell, 31, said she had known Wright for three years and felt safe with him. But she said Wright was different on the night in mid-December 2006 when she last saw him.
Miss Russell was with Wright at his home in London Road, Ipswich. She said he was "nasty" and she was scared.
She described how Wright "wasn't himself" when they prepared for sex on the bed he shared with partner Pam.
"He pinned me down. He never used to do that. It did scare me when he did it because it wasn't like him. He was a bit nasty," she said.
"He said to me 'I don't want to rush tonight, I will pay you extra. I will pay you £100'. Then he heard a bang and he said 'quick, get out'.
"We didn't have sex and that noise probably saved my life. It must've been Pam, thinking about it now. I think it could've been a car door. He couldn't get rid of me quick enough.
"He was trying to help me get dressed. He was really nasty. I had never seen him like that before. He made me go out the front door, which I thought was weird."
"The last night he picked me up he looked all sweaty. He looked like he had been decorating. He had white on his hands. He looked like he had been messing about with cement. He was in jogging bottoms. The other times he was in trousers and jumper."
She added: "His car was immaculate inside that night. It smelt weird, like it had been cleaned."
