Police are investigating whether a man took a deliberate overdose after strangling his girlfriend, after two bodies were pulled from a river on the Norfolk Broads.
The body of a man named locally as John Didier was found in the water of the River Bure near to the body of his partner, Annette Creegan, whose 13-year-old daughter was later found alone on a nearby rented boat.
Following the discovery of the two bodies on 1 September, police announced that they were treating the apparent accident as suspicious.
Det Supt Jes Fry has since said: "All circumstances point to this being a domestic incident and we will continue to investigate in order to put a full set of evidence before the coroner."
A post-mortem carried out on Creegan, who was in her 40s, found evidence that she died of strangulation before entering the water. Although Didier, also in his 40s, was found to have drowned, the couple were found in a very shallow area of the river.
Death in the night
It is feared that the Creegan's daughter was left unaware of the deaths, as Creegan and her boyfriend appear to have died overnight, possibly while the teenager was sleeping.
A spokesman for Norfolk and Suffolk major investigation team said their priority was the welfare of the teenage girl.
Fry said the girl would leave the area under the care of relatives, following the "traumatic" experience.
Didier, Creegan and her daughter were holidaying in the Norfolk Broads over the week and police in the area became suspicious when the Le Boat holiday company reported that the vessel the trio had rented had not been returned.
A mile-long section of the Bure was closed and searched, while local residents were questioned as to the group's whereabouts. The bodies were found on September 1.
