A woman whose body was found in a river alongside that of her partner has been named as Annette Creegan, 49, of Mitcham, Surrey.
She was found in the River Bure on the Norfolk Broads on Sunday. Detectives believe she was dead before entering the water, probably as the result of strangulation.
Her partner, named locally as John Didier, drowned. His death is not thought to be suspicious. Police began a search for the pair after finding a 13-year-old girl alone on a boat when a hire company reported that the vessel had not returned.
Mr Didier, an NHS worker, had family links to Arkansas, USA, and was not a UK national.
Detective Superintendent Jes Fry, head of the Norfolk and Suffolk major investigations team, said: "All circumstances point towards this being a domestic incident."Reuse content
