Kara Alexander drowned or smothered two-year-old Elijah Thomas and Marley Thomas, five, at home in Dagenham, East London.
When their dad Selvin Thomas came to pick up Elijah and Marley for a weekend visit, Alexander claimed they were sleeping.
A CANNABIS addict mum has been found guilty of murdering her two sons then leaving their bodies in a bunk bed for their dad to find.
The dad went to their bedroom to find the boys were both lying dead together on the lower bunk of their shared bed.
Selvin called 999 to tell them "she killed my children" as Alexander fled the home through gardens on to a neighbouring street.
