Sarah Sands was convicted after the Old Bailey heard how she stabbed 77-year-old Michael Pleasted eight times before he bled to death.
32-year-old Sands was acquitted of murder and found guilty of manslaughter, despite the fact she carried a knife to confront Pleasted in what was deemed a “sustained and determined attack”.
Cooke stated that Sands had been proven to have lost control as opposed to committing “vigilante conduct” and as such her act could not be considered murder.
The court also heard how Sands was fully compliant with police, handing herself over to authorities within just a few hours. She also did not remove or destroy any evidence, and is believed to have demonstrated genuine remorse.
Pleasted was awaiting trial at the time of his death, for two counts of sexual assault on two children aged under 13.
He also had 24 previous convictions for crimes spanning three decades, but he had not been placed on the sex offenders register as his crimes were committed prior to 1997.
The defendant argued how she had approached Pleasted to in order to convince him to confess to recent allegations, and that the situation escalated when Sands request was denied and allegedly met with a smirk.
Sands said to jurors:
I was frightened. It was not how it was meant to go. He was meant to listen to me.”
The single mum has already been in custody for 10 months, and could possible be granted parole in 11 months time.
