David McLachlan QC, prosecuting, told a jury at Preston Crown Court that they were dealing with a 'very sad case'.

The court heard that in the days before Willow was allegedly attacked she'd been unwell but a doctor who examined her believed there wasn't anything seriously wrong.
On the day itself - December 3 - Willow's mother Jade Bell gone to work and left her in the care of her partner Lee.
All appeared to be well at first, said Mr McLachlan, but 'matters took a turn for the worse' when the defendant's brother, Daniel Lee, who also lived at the address, messaged Jade at 1.18pm.
'He's seriously not fit to be a father,' he wrote. 'I feel sorry for Willow.'
'Alarm bells' started to ring for Jade, the court heard, and she responded saying 'What's happened?' and 'Is Willow OK?'
But according to Daniel Lee, Mr McLachlan said. that everything 'wasn't OK' and he sent a message to Jade saying how Willow had been crying all day and his brother was 'getting really angry and shouting at her.'

Daniel Lee attempted to calm things down and offered to look after Willow - prompting his brother to pick her up by the ankle and say 'here you go' before putting her back down again.
Their neighbour Samatha Holmes was also said to have become concerned by Willow's crying and had heard bangs and shouts including 'Shut the f*** up or I will…', 'It's done now there's nothing we can do about it',
