A HEARTBROKEN mum is launching her own investigation into how her teenage son died.
Mark Hallsworth, 18, fell as he ran from a fight in Bradley in October 5, 2002.
But his mother, Mandy Jessop, of Rockwood Close, is convinced he was attacked.
An inquest recorded an open verdict last November - but police today said they would be happy to look into any new leads.
Mandy, 44, is now putting out leaflets to friends and neighbours in the hope of unearthing fresh clues.
She believes many unanswered questions still surround Mark's death and is sure somebody saw the fateful moments as he fled from the clash between locals and Kurdish asylum seekers in Gisbourne Road.
She has delivered leaflets to householders living near to where the incident happened at the bottom of Alandale Road in a bid for more information. She also plans to leave them in local shops.
"Somebody said police did come knocking on the door but didn't really ask many questions," said Mandy.
She saw Mark's body a few days after he had died.
"It looked like he'd been hit in the back of the head," she said.
Deputy coroner Mark Hinchliffe
said the injuries the teenager sustained in his fall alone were unlikely to have killed him.
