Constance Marten and Mark Gordon are a couple who went off-grid between 5 January 2023, when their burning car was found abandoned near Bolton, until the date of their arrest on 27 February 2023, in Brighton.

When the couple were subsequently arrested, they were not with their baby, triggering a police search involving over 200 officers across an area of around 90 sq mi (230 km2) extending from Brighton to Newhaven.

However, funds to her were often paid sporadically into her private bank account, until she reminded the trustees that "they had a duty of care" towards her and to maintain her in a comparable manner to her siblings.

[9] The couple were sought by police from 5 January 2023, onwards, when their Peugeot 206 car was found abandoned and on fire next to the M61 motorway in Bolton, Greater Manchester.

[11] After the couple were found without their baby on 27 February, an extensive search encompassing around 90 sq mi (230 km2) of land from Brighton to Newhaven involving over 200 officers, helicopters, sniffer dogs, drones and thermal cameras took place.

[12][13] A baby's remains were found almost 48 hours after the search began, having been wrapped in a plastic bag and hidden inside a shed on an allotment.

[14] On 3 March, the couple appeared before Crawley Magistrates' Court, charged with gross negligence manslaughter, concealing the birth of a child and perverting the course of justice.

On 27 February, the court heard evidence from social services about the sleep dangers that Marten was informed of twice, in relation to her new born baby.

[24] Her partner and co-defendant, Mark Gordon had earlier "changed his mind" about giving evidence and was not called by his barrister John Femi-Ola KC to defend himself under oath.

"[4] Marten concluded her defence evidence on 25 March, by explaining that initially she and Gordon had lied to the police about the circumstance of their daughter's death, scared that they would be blamed and that the charges would "pile up on them".

[31] On 26 June 2024, following the lifting of legal restrictions, it was reported that Marten and Gordon had been found guilty of concealing the birth of a child and perverting the course of justice.
