A 42-year-old woman has been jailed for 16 years for murdering her sons aged seven and 10 by giving them an overdose of pills.
The woman, known as Debby R, tried to commit suicide after killing the boys but survived. She and the children had been under social worker supervision since 2010.
Both her ex-husband and a neighbour alerted social workers to their concerns about the children following her divorce in 2011. Debby R also made similar complaints about her ex-husband.
In 2011 R, the boys and her new partner moved to a residential caravan park and contact with the authorities was broken. The court was told she had used internet to work out a combination of pills to kill herself and her children.
