A woman who backed out of a suicide pact, leaving a man to die alone, has been given a four-year jail term.
Natasha Gordon, 44, was convicted at Leicester Crown Court in December, two years after Matthew Birkinshaw, 31, was found dead in his car at Rutland Water.
She met the postman, from Walsall, West Midlands, on an internet forum where she agreed to be his “suicide partner”.
Gordon, described as a “suicide advocate” in court, was found guilty of encouraging Mr Birkinshaw’s suicide.
The court was told that after exchanging messages the pair travelled together to the UK’s largest reservoir on 17 December 2015.
But Gordon was found by police after leaving Mr Birkinshaw alone in his Fiat Punto, having suffered carbon monoxide poisoning.
An officer who attended the scene said Ms Gordon told him Mr Birkinshaw had given her £60 to get home but “asked her not to change his mind”.
The court heard Gordon contacted other men about more deals within hours of Mr Birkinshaw’s death.
Prosecutor Tim Cray said she was “prepared to say to people she hardly knew” that taking their own life “was the right thing to do”.
Sentencing judge Mrs Justice Bobbie Cheema-Grubb told Gordon, from Paston, Peterborough, she was “gripped by self-centredness” and had no “settled intention” to commit suicide herself.
“I have found you misled [Mr Birkinshaw] into believing you were genuine and firmly intent on committing suicide with him, although you were not fully committed.”
Gordon, who had a history of depression and had previously attempted to kill herself, had denied the charge and said she had no input into his decision to die.
After they met online, Gordon sent a message to Mr Birkinshaw which said: “I really can’t wait to go tomorrow, I hope you do not change your mind.”
Mr Birkinshaw then travelled through the night to the defendant’s home.
Mrs Justice Cheema-Grubb told Gordon: “He was a stranger to you. You took no trouble to find out anything about him. You introduced the method that he used and advised him on how it was to be deployed.
“He may not have gone through with it if you had not accompanied him.”
How was she caught?
On 17 December 2015, Ms Gordon contacted her partner from Rutland Water to tell him she was going to kill herself.
He then raised the alarm with the police, who found Ms Gordon in a leopard-print coat with matching hat and leggings.
It was then later when Ms Gordon disclosed that police should be looking for “another person at risk” – Mr Birkinshaw.
The court heard that Royal Mail employee Mr Birkinshaw was found locked in the car and a police officer had to break the window with his baton.
Mr Birkinshaw, who had been in good health and had a stable girlfriend, was pronounced dead at 19:24 GMT.
The police then investigated Gordon and discovered the messages.
Mr Birkinshaw’s parents said upon her conviction that it had been the “longest, hardest, saddest and most traumatic two years of our lives”.
They also urged others who may be struggling to speak to some that has “your best interests at heart”.
“If this message averts one tragedy, it will mean that something positive has come out of the death of such a beautiful and much-loved son.”
