'He's unconscious because I nearly drowned him': Text messages from Daniel Pelka's mother to boyfriend

When Magdelena Luczak was arrested at her home she was clutching the mobile phone which would help to convict her of murder.

Text messages sent from the phone provided evidence of the defendants' drug and alcohol abuse, their remorseless mistreatment of Daniel Pelka, and their attempts to keep the abuse from teachers, social workers and medical staff.

Here are some of the text messages which passed between Mariusz Krezolek and Luczak, translated into English from Polish for the court proceedings:

• 7th October 2011

• 21st October 2011

• 15th November 2011

• 14th December 2011

• 1st February 2012

• 2nd February 2012

• 8th February 2012

The final message was sent by Luczak to Krezolek, as Daniel lay dying of a brain injury:

Google searches were also conducted on the couple's home computer in Daniel's final hours, showing they were trying to work out what injuries he had suffered - and how they continued with everyday chores such as sourcing car tyres.
