A couple in United Kingdom have been jailed for 14 years for the gross negligence manslaughter of their newborn daughter.
She met her death when they went on the run with her to avoid dealing with social services.
Their four other children had previously been taken into care.
Constance Marten, 38, and Mark Gordon, 51, were sentenced on Monday after being found guilty in July following a lengthy retrial at the Old Bailey.
The decomposed body of their baby, Victoria, was found in a shopping bag in Brighton in 2023.
Police had been searching for the couple for 53 days after officers found evidence of a recent birth in a burnt-out car near Bolton.
Judge Mark Lucraft KC, Passing sentence, told the couple "neither of you gave much thought to the care or welfare of your baby".
They were sentenced on the basis Victoria died of hypothermia - both defendants had argued against that during the hearing.
Gordon will serve a further four years on extended licence, the judge said.
There was no reaction from either defendant as they were sentenced.
The first trial found Marten and Gordon guilty of concealing the birth of a child.
They also perverted the course of justice by not reporting her death but the jury failed to reach a verdict on the manslaughter charge.
The court heard that, when Marten was heavily pregnant, they had decided to live off grid to avoid Victoria being taken off them by social care authorities.
During the police manhunt that spanned different parts of England once the circumstances of the birth were uncovered, the couple slept outside and took steps to avoid being found.
They were eventually located on 27th February 2023, and Victoria was discovered dead two days later in the Hollingbury area of Brighton.
She had died while the couple was living in a tent on the South Downs in January that year.
In their trial, the couple had said Victoria's death was a tragic accident after Marten fell asleep holding the baby.
Evidence from experts on hypothermia, one of whom described the conditions the newborn would have experienced living in a tent in the middle of winter nailed them.
When in court, both displayed disruptive and unpredictable behaviour, disrespected the judge, were rude to dock officers and would often talk during proceedings.
During the latter stages of the retrial, Gordon parted company with his legal team and took on the role of representing himself in court, despite having no legal training.
Disruption continued during Monday's sentencing hearing, during which the judge told off both defendants for passing notes in the dock. He told them it showed "a complete lack of respect".
During the retrial, the jurors were told of Marten's privileged upbringing in a wealthy family.
They also learned that Gordon had been convicted of rape in Florida in 1989 when he was aged 14.
