Daniel Pelka's stepfather found dead in prison
The man who was convicted of murdering a four-year-old boy in Coventry has been found dead in jail.
Mariusz Krezolek, 36, was found dead in his cells by guards at about 08:30 GMT on 27 January at Full Sutton prison.
He was sentenced to a minimum of 30 years in jail in 2013 after being convicted of murdering his step-son, four-year-old Daniel Pelka.
Daniel's mother, Magdalena Luczak, who was also convicted over his death, was found hanged in her cell in July 2015.
A spokesman for the prison service said Krezolek was found "unresponsive" in his cell, and despite efforts to revive him he was pronounced dead shortly afterwards.
"As with all deaths in custody, there will be an investigation by the independent Prisons and Probation Ombudsman," they said.
