Constance Marten, 37, and Mark Gordon, 50, are currently on trial for the manslaughter of their daughter Victoria, who died under tragic circumstances while they were living off-grid during winter.

The couple, who have no fixed address, deny charges of gross negligence manslaughter and causing or allowing their daughter's death between January 4 and February 27, 2023.

During the trial at the Old Bailey, it was revealed that Marten and Gordon traveled to the South Downs in early 2023 to evade a police search concerning their fifth child being taken into care.

Victoria's body was discovered in a shopping bag inside a disused shed near Brighton after the couple's arrest on February 27, 2023.

The prosecution claims that Victoria either died from hypothermia or was smothered while co-sleeping in a flimsy tent, and that she was inadequately dressed in a babygrow.

Evidence suggested that Victoria was inadequately clothed, wearing only a babygrow, and that Marten had gotten wet while carrying the baby under her coat, further compromising the child's warmth.

Professor George Havenith provided evidence regarding the risks of hypothermia faced by Victoria in their living conditions, conducting experiments based on temperatures and conditions similar to those experienced by the family between January 8 and 10, 2023.

His findings indicated that the micro-climate created under Marten's oversized coat was unsafe, exposing the baby to significant cold stress and a high risk of hypothermia.

The couple reportedly used summer sleeping bags during winter camping, which were deemed unsuitable for the cold UK countryside in January 2023.

Havenith concluded that Victoria was exposed to significant cold stress, increasing the risk of hypothermia in the environment described.

The trial is ongoing, with the court continuing to explore the circumstances surrounding Victoria's tragic death.
