Magdelena Luczak and her son Daniel
The mother of murdered Daniel Pelka hanged herself in prison, an inquest has heard.
Magdelena Luczak, 29, was found dead in her prison cell at HMP Foston Hall in Derbyshire at 7.15am on Tuesday.
An inquest into her death was opened and adjourned at Derbyshire Coroner's Court this morning. The cause of death was recorded as hanging.
Luczak and her partner Mariusz Krezolek, both originally from Poland, were convicted of murder and sentenced to at least 30 years in jail in August 2013 after blaming each other for the head injury which ultimately caused Daniel's death.
Daniel, who was born on July 15 2007, weighed just 1st 9lbs when he died in March 2012.
The boy was the victim of what was described in court as an "incomprehensible cycle of cruelty and violence" which left him looking like "a concentration camp victim".
During their trial, the court was told Daniel was imprisoned in a room with the door handles removed, was fed salt when he asked for a drink, deprived of food and forced to defecate in his own bed.
He was so hungry he would steal food from other children, who subsequently had to lock their food away.
Staff said he picked up muddy and dirty pancakes from the floor, ate out of bins and even tried to eat beans which had been planted in soil as part of a school experiment.
