‘He didn’t hit a tree or a ditch, he was just found flat on his back and the quad bike next to him on its side,’ Mrs Cason explains.
He wasn’t wearing a helmet, and as he fell struck the back of his head. Killing him instantly.
Mrs Cason said she found out when the police came to her door that her eldest boy was gone - but they weren’t allowed to see him yet while police assessed the area.
‘That was hard to take, and if I had my time over I wish I’d just gone out there.’
Sam’s mum is now campaigning for stricter regulations for using quad bikes on private land - including banning children under 16 from riding them either as a driver or passenger.
'I don’t want to stop kids from helping on farms, but there has to be a middle ground where kids are kept safe.'
