Claire Colebourn, 36, did not react as the jury foreman read out the verdict at Winchester Crown Court, Hampshire, today
A former biology teacher has been convicted of murdering her three-year-old daughter by drowning her in the bath.
Claire Colebourn, 36, did not react as jurors returned their verdict at Winchester Crown Court in Hampshire today.
The court had heard she hit “rock bottom” after her high-flying husband Michael ended their 16-year-relationship.
She woke the couple’s little girl, Bethan, at their £400,000 home in Fordingbridge, Hampshire, in the early hours of October 19, 2017.
She then led the youngster to the bath and drowned her by holding her body down under the water, jurors were told.
Colebourn, who used to teach Sixth Form, was discovered by her mother about 14 hours later, in a diabetic coma.
She initially denied all memory of the incident, but later recalled how Bethan agreed to have a bath in the middle of the night.
She told police: “Sadly, my little girl trusted me completely.”
There was silence in the public gallery this afternoon as Colebourn was convicted of murder by jurors.
The five women and six men had deliberated for around two-and-a-half hours following an eight-day trial.
Colebourn had met Mr Colebourn, now the chief executive of luxury marine interior company Trimline, at university.
She admitted she killed Bethan but said she only wanted to “save” her from the little girl’s father.
However, jurors rejected her account, delivered during a fraught and emotional day’s evidence from the witness box on Wednesday.
Kerry Maylin, prosecuting, said: “Bethan was three years old, she was a much loved daughter of Claire and Michael Colebourn, but she was found dead at her home.
“Claire Colebourn, when Bethan was found, was also in the house and she was at the time suffering a diabetic episode.
Bethan died because she had been put in the bath at home and held under the water, the act was completed by her mother.”
The prosecutor said that just over a month before Bethan’s death, her parents had separated and Mr Colebourn had moved out.
Miss Maylin said their relationship had been difficult and the defendant went on to make “unfounded accusations” on Facebook and in an email sent to his work that her husband was having an affair with the company’s finance director.
In the email to Trimline, she wrote: “He has been having an affair with his finance director at work, everything has been pre-planned, of course the finances.
“They are aiming to take over the business and set up a new life together.”
Miss Maylin said Colebourn also told friends she had visited Ms Futcher’s home looking for her husband’s car.
The lawyer said Colebourn also became worried, without foundation, that Mr Colebourn was monitoring her computer and arranged for an IT firm to supply her with a new laptop and wifi at her home.
She said that within minutes of receiving the new computer in October, she began searching for suicide-related websites.
Miss Maylin said that following her arrest, the mum told medical staff she had tried to kill herself the previous day.
The prosecutor said a doctor described how she was “only emotional when discussing the fact Michael Colebourn had left her and her daughter and her father had done the same to her mother”.
She later wrote in a letter intercepted at a hospital she was staying in: “In my eyes I saved her, everything over those days is a blur.”
And she told police: “I am responsible for Bethan’s death because she drowned and I am responsible for it.
“Bethan drowned because I was there, I held her under the water.”
An NSPCC spokesperson said today: “This is a desperately sad case in which a young child lost her life in the most tragic of circumstances.
“Bethan would have looked to her mother for love and protection. Sadly, Colebourn failed her daughter in the worst possible way.
“We all have a responsibility to protect children. Adults can report their concerns to the NSPCC helpline on 0808 800 5000 or dial 999 if a child is in immediate danger.”
Colebourn will be sentenced on Monday morning.
