A wealthy aristocrat was allegedly spotted walking in Stanmer Park with her lifeless baby in a sling more than a month after going on the run with her partner.
Constance Marten, 36, and Mark Gordon, 49, are on trial at the Old Bailey accused of the manslaughter of their daughter Victoria.
It is alleged the couple travelled across England and lived off-grid on the South Downs in a bid to keep the baby after four other children were taken into care.
On Thursday 5 January last year, Greater Manchester Police started a missing persons inquiry after finding a placenta in the couple’s burnt-out car on a motorway near Bolton.
Abandoned items near the Peugeot on the M61 included a bible, a bag of more than 30 mobile phones, five used nappies and a cat in a cat box.
The defendants spent hundreds of pounds on taxis taking them from the north west to Essex, London and the south coast, jurors were told.
On Sunday 19 February, Pauline Mason and her husband went to Stanmer Park in Brighton for some “fresh air”.
Mrs Mason was in a mobility scooter and her husband was walking when she saw a tent near Stoney Mere Way.
She told jurors: “I noticed a tent. The tent was royal blue. It was not very big. I just thought it might be a hiker.
“My husband had walked ahead of me and I shouted to him, ‘Come over. What’s that tent doing there?’
“He said, ‘Dunno. Someone is sleeping out on a cold night.’ I was taken aback by it then continued on my scooter.”
Further on, she noticed a “mum with baby”, Mrs Mason said.
Tom Little, prosecuting, asked: “What did you notice, if anything, about the baby?”
Mrs Mason said: “The mother was focused on the baby. Her eyes were totally focused on that baby and my eyes went from her to the baby.
“The baby was in a sling. She was holding her around the baby’s head to steady it.”
The child was very pale, did not make any sound and her head was “wobbling”, “floppy” and “unsteady”, the witness said.
She was “very surprised” to see the child had no hat, socks or booties on and was only wearing a cardigan and leggings.
Mrs Mason said that the woman looked tired and she felt sorry for her.
A few steps behind was Gordon, she said, adding: “He looked at me and acknowledged that I had looked at the baby and gave me a smile.”
Mr Little said: “At that point in time, as you had seen the baby for six to eight seconds, you then continued on your fresh air turn around Stanmer Park. Did you think the baby was alive?”
Mrs Mason replied: “I kept thinking and thinking about that baby. I thought that the colour, it did not go.”
She spoke about her experience that “mixed-race” babies were “rosy cheeked”, adding: “There was no colour and that baby was white.
“I do think that baby had died. It was dead.”
Asked if anything else caused her to think that, she said: “It was inappropriately dressed. There was no blanket, no hat, no socks, thin cardigan.”
Mrs Mason said that she continued up the path but looked back towards the couple because she “could not believe” what she had seen.
John Femi-Ola, cross-examining for Gordon, asked if she could have been mistaken about seeing him.
She replied: “Yes. I might have been. But I believe that they were connected and as soon as I saw her and him behind her I knew they were together.”
On seeing the baby, she said: “I was quite shocked when I saw it. I did not want to believe it.
“I did not want to know it was dead.”
On Monday 27 February, Marten and Gordon were arrested in Brighton.
Two days later, Victoria’s body was found in a Lidl supermarket bag for life, covered in rubbish in a disused shed.
Previously, jurors were shown CCTV of Victoria alive and moving around with the defendants in East Ham, east London, on Saturday 7 January last year.
The couple moved on to Whitechapel, where Gordon had bought a two-person tent and camping bedding, including a children’s unicorn sleeping bag, in Argos, the court was told.
The couple allegedly abandoned a buggy and were carrying Argos bags and a Lidl bag when they got into a black cab shortly after midnight on Sunday 8 January.
In a statement read to the court, taxi driver Abdirisakh Mohamud said that he became “suspicious” and “uncomfortable” during the journey.
The male passenger allegedly asked the driver if he was a Muslim, whether he was “trustworthy” and if there were cameras in the cab.
Mr Mohamud said that he told the man that there were cameras, even though there were not, because he wanted to feel “safe”.
The man then asked him: “Are you sharing this conversation with anyone?”
Mr Mohamud said: “No.”
He asked the couple why they were wearing blue covid facemasks and the woman said that she was a Muslim and it was her “hijab”, the court was told.
On being told by the driver that it was not a hijab, she allegedly told him that it was the only thing she had.
The man said that he was wearing a mask because he “had a problem with his hair”, the witness said.
Mr Mohamud said that he decided to drop the couple off early in Green Lanes, Haringey, rather than the Enfield Tesco Extra where they had asked to go.
He said: “The more I thought about it, the more concerned I felt about the baby.”
Another taxi driver, Hasan Guzel, described hearing “meowing” noises when he drove the defendants from Haringey to Newhaven early on Sunday 8 January.
He said: “I heard what sounded like a cat meowing. I was annoyed at first because I thought she had a pet without telling me.
“I could see it was a baby. I could see the noise was coming from a baby.
“I thought, why didn’t she tell me about this. It’s been nearly four hours we have been travelling.”
He said that when he dropped them in Newhaven, it was cold and dark and he was “concerned as to what they were going to do next”.
The couple were captured on CCTV heading towards the South Downs at around 6.30am and were not spotted again until they were seen at a Texaco garage four days later, on Thursday 12 January.
The defendants, of no fixed address, deny manslaughter by gross negligence between Wednesday 4 January and Monday 27 February last year.
They are also charged with perverting the course of justice, concealing the birth of a child, child cruelty and causing or allowing the death of a child.
The Old Bailey trial continues.
