The mother of a baby whose body was found in a water-filled pit more than a quarter of a century ago has been traced, detectives have revealed.
The news comes almost exactly a year after the remains which were discovered in Weasenham St Peter in 1988, were exhumed for DNA testing to take place.
Police have described the development as a “significant breakthrough”, though prosecutors still have to decide whether to press charges.
Comparisons of the boy’s DNA with samples in the national database identified a relative, from where the mother was also traced.
Police have now revealed that the woman, who was initially arrested on suspicion of infanticide, revealed she had hidden the pregnancy from relatives and friends and delivered the baby, which was stillborn, alone.
The case has been referred to the Crown Prosecution Service, who will decide whether the woman should be charged with offences including failing to register a birth and preventing a lawful burial.
But Det Chf Insp Andy Guy, who led the new inquiry, said officers were satisfied that no-one else was involved.
He said: “While it is immensely pleasing to solve a case which has remained a mystery for 27 years, one can only feel for the lady involved who has had to carry this enormous burden in secret for all this time.
“What this does highlight is that unsolved cases in Norfolk and Suffolk are never closed and we will always respond to new information or new technology in order to resolve them.”
The body of the infant was first discovered in a location known as Windmill Pit in Weasenham St Peter on June 5, 1988. It is believed the boy had been in the water for several weeks before he was found.
Initial inquiries failed to trace his parents, but the case was re-opened last year after new information came to light.
The boy’s body was exhumed in April 2014 for DNA testing to be carried out and reburied on the anniversary of its discovery, as detectives launched a new appeal to finally solve the mystery.
