30 year old Deveca Rose, (pictured above) was found guilty of four counts of manslaughter following the blaze in Sutton in December 2021.
She’d been at Sainsbury’s when the flames broke out.
Judge Mark Lucraft KC described the case as “deeply tragic”.

Emma Currie, of the Crown Prosecution Service, said: “This was an entirely preventable tragedy, resulting in the devastating loss of four young boys who had their whole lives ahead of them.
“Deveca Rose not only left Bryson, Kyson, Logan and Leyton unattended to go shopping, but she then lied about the circumstances to avoid responsibility for their tragic deaths.
“Our thoughts remain with their family, friends and wider community today – we recognise that nothing will bring back the young lives that have been lost.”
Kerrie Hoath is the children’s paternal step-grandmother.
Detective Chief Inspector Samantha Townsend of the Met’s Specialist Crime Command said:
“This has been a deeply upsetting investigation for everyone involved.
“Deveca Rose was a mother who placed her own self-interest above the safety of her children.
“Had she not left the children to go shopping, she may have been able to put out the fire, or at the very least, got the children to safety.
“Instead of taking responsibility for her actions, she invented a story that was built around a babysitter whose very existence could not be confirmed.
“The sadness at the needless loss of four young lives is beyond our comprehension.
“I cannot begin to imagine the devastation felt by the children’s wider family and loved ones and our thoughts are with them all today.”
