A GRIEVING Huddersfield mum today hit out after an inquest into the death of her teenage son.
The mother of eighteen-year-old Mark Hallsworth, also known as Mark Jessop, pledged to continue her quest to find out how her son died.
He collapsed while running from a group of Kurdish asylum seekers in Gisbourne Road, Bradley, on October 5 last year.
At his inquest yesterday, it was suggested an undetected heart condition triggered by the chase could have caused Mark to suddenly collapse.
Recording an open verdict, West Yorkshire's deputy coroner Mark Hinchliffe said the injuries Mark sustained in his fall were unlikely to have killed him.
But Mark's mother Mandy Jessop was unhappy with the verdict.
She claimed unanswered questions still surrounded his death.
She said she was sure her son was attacked before he collapsed and that more evidence would eventually come to light.
She rejected the suggestion he had a heart condition.
"He's been chased by asylum seekers and all of a sudden just drops dead? I don't buy it."
She claimed one person had seen Mark get attacked, but had not yet contacted the police.
She said Mark was fit and healthy.
"This isn't the end of it. Not by a long shot."
On the evening Mark died, an argument had broken out at about 8pm between youths and the Kurdish asylum seekers.
Mark, who lived at Rockwood Close, Bradley, with his mum, was running from the disturbance towards Stuart Place when witnesses saw him fall next to a parked car, hitting his head as he did so. He died later at the Huddersfield Royal Infirmary.
Detectives and pathologists were unable to uncover any evidence to suggest Mark was attacked before he fell.
Dr Philip Lumb, a consultant pathologist for the Home Office, carried out the post-mortem.
He discovered Mark suffered cuts, grazes and bruises to the right-hand-side of his face.
His right cheekbone was fractured, consistent with a heavy fall.
Dr Lumb told the inquest that in certain people physical or emotional stress could trigger a cardiac disorder, leading to collapse.
In a statement read out at the inquest, Mrs Jessop said Mark had once blacked out when he saw his grandmother being attacked.
Mark's friends Declan Storey and Scott Scandling were with Mark when he died and gave evidence at the inquest.
Declan watched Mark jogging away from the trouble.
"He seemed to be staggering a little bit. Then he just went over and hit his head on the corner of the car."
Scott was walking with Mark down Alandale Road before they were chased.
"There was lots of shouting and I just heard a bang and turned round and saw Mark on the floor at the bottom of Gisbourne Road."
Det Supt Graham Shaw, who led the inquiry, said the case had initially been treated as murder.
Five of the six asylum seekers living in Alandale Road were arrested and questioned.
They told police bottles had been thrown at their house, triggering the fight.
Three local youths were also arrested.
Mr Hinchliffe concluded of Mark's fall: "No-one has come forward to the police to say they saw him being assaulted."
But he conceded a number of questions had not been answered satisfactorily.
