Porton (pictured) murdered her two young daughters because they interfered with her job as a sex worker and now faces life in jail
A mother who killed her two young children because 'they got in the way' of her job as a sex worker faces life in jail after she was found guilty of their murders.
Part-time model Louise Porton, 23, suffocated Lexi Draper, three, and strangled 16-month-old Scarlett Vaughan, just 18 days later.
The single mother, who earned a living sleeping with men she met online and sending them explicit pictures and videos, was today found guilty of two counts of murder.
Porton claimed her daughters died naturally but acted 'like someone had lost their goldfish' when she was informed of their deaths.
She stood poker-faced as jurors returned verdicts after a four-week trial.
Jurors heard Porton had accepted 41 friend requests on a dating app just a day after the first child Lexi died, and was described by prosecutors as being 'calm and emotionless' following Scarlett's death.
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.

The 23-year-old 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, on February 1.

Prosecutors said it had appeared to a funeral arranger that Porton was 'using FaceTime and that she was speaking to a man'.
Jurors were told that after police seized her phone, they uncovered searches including how long it took a dead body 'to go cold up to the shoulder' and 'five weird things that happen when you die'.
Opening the Crown's case at the start of the trial, prosecutor Oliver Saxby QC said: 'The overwhelming inference is that Lexi and Scarlett died because someone deliberately interfered with their breathing.
'That someone can only have been this defendant.'
Both children had symptoms consistent with deliberate airway obstruction and Scarlett had signs of recent bleeding in her neck tissue, suggestive of neck compression, jurors heard.
Mr Saxby said specialist doctors could find no 'natural reason' for why either child had died.
