Doctors have been unable to explain what caused the death of a healthy 16-year-old at his family home in Chorley.
However, they say it is likely Daniel Nicholls suffered a seizure.
The 16-year-old had been fit and healthy and had helped to clean the drive at his grandmother’ss house the day before he died.
Deputy coroner Simon Jones recorded a verdict of natural causes after ruling out any suspicious circumstances surrounding the tragic death of the Runshaw College student at an inquest held in Preston.
Daniel’s devastated mum, Lorraine, said; “I just miss him with every breath I take.”
Daniel was found in the living room of his family home in The Spinney, Chorley, at around 2pm on December 10.
His mother had left him a list of jobs to do when she went to work but when she could not contact her son by phone she asked her daughter, Leanne, to go and check on him.
A post-mortem examination, carried out by Prof Timothy Dawson proved inconclusive, but the consultant neuropathologist said it was probable that Daniel died from a seizure.
He told the family: “His heart stopped and he stopped breathing. I am sure Daniel wouldn’t have known anything about it.”
Paying tribute to her son, Ms Nicholls said: “He was a lovely little boy who was growing up to be a fun loving, humorous, caring young man.
“Everybody liked him and so many people miss him.
“He was a good lad. He didn’t have a bad bone in his body. He was a genuine, good boy.”
Deputy coroner Simon Jones said: “Daniel had no history of any medical condition. It is also clear from the evidence there is nothing suspicious or untoward about Daniel’s death.
“I am entirely satisfied whatever the cause of death it was from natural causes.”
