COPDOCK, 8 DEC, TANIA NICOL
Tania Nicol's body was found in Copdock. Police want to trace her clothing
Police divers searching the brook at Copdock found a second naked body near a mill. She was identified as Tania Nicol, 19, another prostitute missing since 30 October.
When she was last seen, she was wearing a light coloured top, mid-blue cut-off jeans, and pink sparkly high heeled shoes.
Ms Nicol's body was found in Belstead Brook - the same stretch of water as Gemma Adams but two miles away.
