A mother murdered her 3 year old daughter after the breakup of her marriage.

A mother who murdered her three-year-old daughter following the
break-up of her marriage has been jailed for life.
Claire Colebourn, 36, drowned Bethan in a bath at their family
home in Fordingbridge, Hampshire, in 2017.
Colebourn tried to take her own life after killing her daughter but
was revived by paramedics. She was found guilty of murder on
Friday.
She showed no emotion as the judge at Winchester Crown Court
told her she must serve at least 18 years.
Mrs Justice Johannah Cutts said Bethan was "a beautiful little girl
who was full of life. She had everything to live for".
The judge said Colebourn should have asked for help after her life
became an "emotional rollercoaster" when her marriage broke
down and her husband left the family home.
Despite being in a "highly emotional state" there was "no evidence
of mental illness" and there was "no excuse" for the killing, the
judge said.
"You were her mother, you were responsible for her care and her
wellbeing.
"You wanted to deny your husband the chance to bring up
Bethan. Bethan was entitled to and deserved a life," the judge
added.
In a statement released through the police, Michael Colebourn
said: "There are no words to describe the past 18 months. The
one thing in my life that gave me purpose has gone.
"My beautiful daughter has been taken from me in such a cold
and callous manner at the very hands of the one other person
that should have protected her and kept her safe.
"Throughout the criminal trial, I, and all those that loved Bethan
have had to endure the heartbreak of listening to her last
moments.
"I have also had to suffer endless unfounded allegations and lies
made against me with no opportunity to respond.
"I desperately miss being a daddy - we would have such great
times together; Bethan's laugh was infectious and her energy was
endless. There is not a second in the day that goes by that I am
not thinking about her."
Former biology teacher Colebourn was found guilty of murder by
unanimous verdict on Friday after the 11-strong jury deliberated
for two hours. She did not react as the verdict was delivered.
Bethan was found lying in bed at her home in Whitsbury Road by
her grandmother on 19 October 2017. Paramedics were unable
to revive her.
Prosecutors said Colebourn had an "unfounded" belief that her
husband Michael, a company chief executive, was having an
affair.
In a Facebook post Colebourn wrote: "Michael walked out on his
family on 7 September and we haven't seen him since.
"He has been having an affair with his financial director at work.
Everything has been pre-planned.
"They are aiming to conquer the business and set up a new life
together."
Colebourn set an alarm for 03:00 and then took Bethan to the
bathroom where she ran a bath and drowned her.
She had told police: "She woke up... she put her hands on my
cheeks, told me she loved me and said 'I don't want a bath,
mummy, I don't want a bath'."
'Personality disorder'
She then attempted to take own life by repeatedly injecting herself
with insulin.
During the trial, it was heard Colebourn had searched for
websites about suicide and drowning.
Karim Khalil QC, defending, said Colebourn appeared to have a
personality disorder but this was disputed by experts.
Colebourn has spent nearly a year in custody which will be
deducted from the minimum term before she faces the parole
board which will determine whether she is ever released.
