Constance Marten and her lover Mark Gordon are to be charged with gross negligence manslaughter, concealing a birth and perverting the course of justice after a baby’s body was found in a woodland.

The couple were arrested in Brighton on Monday night, ending a nationwide police hunt that began when they fled seven weeks ago with their baby.

But aristocrat Marten, 35, and partner Gordon, 48, were without the newborn when officers swooped in to arrest them.

The Crown Prosecution Service has this evening confirmed it has authorised charges to be brought against the couple, who will appear at Brighton Magistrates’ Court tomorrow morning. 

Marten and Gordon are also to be charged with concealing the birth of a child and perverting the course of justice.

It comes as a vigil has been held the the baby outside St Mary Magdalen Church, Coldean, East Sussex, tonight – close to where remains have been found in the search.

Mourners were seen holding candles and lighting a small fire outside the church to pay tribute.   

The remains of a newborn were found close to a public footpath in an area not yet searched by police in Brighton yesterday. 

Officers have so far not been unable to confirm the infant’s gender and a post-mortem has not yet taken place, while police say it is also too early to provide a specific date of death.

Speaking at a press conference today, Detective Superintendent Lewis Basford confirmed the case has been referred to the police watchdog.

He said: ‘At this stage we have not yet been able to confirm the baby’s gender and post-mortem examination has not yet taken place.

‘Despite this, based on our inquiries we’ve carried out so far, we believe sadly the baby may have been dead for some time before they were found. It is too early for us to provide a more specific date.

‘Because we believe the death occurred during the course of a missing person investigation we have made a mandatory referral to the Independent Office for Police Conduct (IOPC). This is standard protocol for such circumstances.

A spokesman for the IOPC said in a statement that the watchdog is ‘currently assessing the referral to determine what, if any, further action is required from us’.

Det Supt Basford added that officers investigating the case are ‘devastated’ by its outcome as he confirmed Marten and Gordon remain in custody – with the warrant for their detention extended until Thursday evening.

‘We are truly devastated by the outcome and we know this emotion is being felt here in Brighton and across the country today,” he said.

‘We know there are still many unanswered questions, and it is important that we give the investigation team the time and space they need to establish more details about the circumstances of this tragic death.’

Chief Superintendent James Collis, of Sussex Police, added that officers have been ‘overwhelmed by kind messages and support’ from the public and thanked ‘the huge number of people who have helped or offered to help in any way that they can’.
