Police are to return to the lake at the University of East Anglia in Norwich where a woman's body was found last week to carry out further searches.
The woman was fully clothed when she was discovered floating face down in the water. She had short dark brown hair which had been dyed auburn or dark red and was in her late thirties or early forties.
Yesterday (Monday) police released a photo of the black and flower printed dress she was wearing when her body was discovered.
A body found in the River Lee in Hertfordshire has been confirmed by police as missing pensioner Gwyn Morris.
Mr Morris, who was 88, went missing in December from the Willowthorpe Care Home in Stanstead Abbots. His body was discovered at Feildes Weir Lock in Hoddesdon.
