The death of a woman whose body was found in the river Bure in Norfolk alongside her partner is being treated as suspicious, police have said.
Post-mortem tests on the man and woman, both in their 40s and from the Surrey area, were carried out on Monday.
They found the woman died before entering the water, probably as the result of strangulation. The man died as the result of drowning.
Officers had launched a search after finding the woman's daughter, a 13-year-old girl, alone but unharmed on a cruiser on the Norfolk Broads on Saturday.
The man's death is not being treated as suspicious. Further forensic tests will be carried out on the woman's body.
Detective Superintendent Jes Fry, of the joint Norfolk and Suffolk Major Investigation Team, said:
"We are not looking for anyone else in connection with this incident."
Police in Norfolk have tonight named the man found drowned in the Broads at the weekend.
A woman, found dead in the Norfolk Broads at the weekend, has been named as Annette Creegan, 49, from Mitcham in Surrey.
A man found dead in the Norfolk Broads at the weekend is expected to be formally identified by police later today.
