A mother has been told she could spend the rest of her life in jail after admitting to the murder of her two teenage sons.
Thirty-five-year-old Sarah Barrass sobbed as she pleaded guilty to murdering sons Tristan, 13, and Blake, 14, in Sheffield.
She also admitted conspiracy to murder six of her children, including Tristan and Blake.
Family member Brandon Machin, 39, admitted the same charges at Sheffield Crown court.
No details were given in court about what happened to the two boys, and South Yorkshire Police has never released the cause of their deaths.
All four of the surviving children are under the age of 13.
Judge Jeremy Richardson QC told the pair: "No words of mine can ever fully reflect the enormity of what you have both done.
"The crimes you have committed quite frankly speak for themselves.
“The murder of two children, the attempted murder of four children and the over-arching conspiracy to murder those children.
"I repeat, those crimes speak for themselves. I have little doubt that each of you will in due course be sentenced to several terms of life imprisonment.”
According to the charges, the conspiracy to murder the six children took place between May 14 and May 20 and the murders took place on May 24.
The attempted murders of Tristan, Blake and two other children, who cannot be named, took place the day before, on May 23. The pair also attempted to murder one of these children again on May 24.
The pair will be sentenced on November 12.
