A mother who murdered her two young daughters because they "got in the way" of her sex life has been jailed for life.
Louise Porton killed three-year-old Lexi Draper and 17-month-old Scarlett Vaughan less than three weeks apart.
She suffocated Lexi in the early hours of January 15, 2018, and was then heard laughing at a funeral parlour two days before killing Scarlett on February 1.
She only called the emergency services when she knew they were dead.
When Lexi was ill in hospital, just over a week before she died, Porton took topless photos in the toilets and was arranging to perform sex acts for money with a man she had met through a website.
And police said it was clear from the evidence that Porton had tried to kill her three-year-old twice before.
Porton denied killing her children but was found guilty by a jury at Birmingham Crown Court on Thursday, and jailed on Friday for life with a minimum term of 32 years.
The judge said she was sure Porton had been responsible for events leading to Lexi's earlier admissions to hospital on January 2 and 4, during which her life was only saved by skilled resuscitation by paramedics.
At the time, she used her Google account to search for "Why did my 3 year(-old) stop breathing", and "How long after drowning can someone be resuscitated?"
The judge added that the night Lexi was killed, Porton made further "sinister" internet searches about death.
"I am left in no doubt that you delayed calling for an ambulance until you were sure she was dead and could not be resuscitated," she said.
The 23-year-old, of Skiddaw, Rugby, Warwickshire, suffocated Lexi in the early hours of January 15 last year and was then heard "laughing" at a funeral parlour two days before killing Scarlett just over two weeks later,
Post-mortem examinations revealed signs of previous injuries, while Scarlett "had signs of prior airway obstruction".
Porton's only previous criminal history was a caution for wasting police time aged 15.
The judge said: "Those who loved Lexi and Scarlett have been left bewildered as to how and why you could have done something so evil. Your actions have devastated so many lives."
The children's father Chris Draper, who never met Scarlett, said he felt "broken", with "nothing to live for".
Mr Draper, who was in court for sentencing, said: "I hate Louise. No punishment will ever be enough, as I will never get my daughters back."
Porton, who sat in the dock throughout the hearing looking at her feet with her head resting on her hands, did not react.
