19-year-old Harry William Column died of traumatic brain injury at Little Stonegate last June 24th after falling from the roof above.
Alison Norton, an aide to York and North Yorkshire, concluded that Callum died as a result of misfortune.
Mr. Callum worked as a barman at Kennedy's bar and restaurant in Little Stonegate.
In a statement, Callum's mother, Eileen Callum, said: “He loved this job that suited his lifestyle.”
“He loved his family,” she said, and “enjoying” the period of his life “happy” and “enjoying.”
“His memory lives on through his family and many friends,” Callum said.
Calam and the two friends he worked with went out for drinks with the others at the bar next door after finishing work the evening of June 23rd last year.
They left the last bar at 4am before Mr. Callum and his two friends went to McDonald's on Break Street.
An interrogation was then heard, one of his friends said he had previously climbed onto the roof above the Davigate retail unit.
He said that you can access the roof by climbing the building's fence and walking through the scaffolding.
Norton says a friend crossed the fence and climbed to the construction site, and Callum followed him, leaving the other friends on the street.
The two went to the roof of the building and then asked other friends to join them.
It was a dry night and enough light to see.
The roof area was large and had areas of various heights.
Callum and others were “hopping” between levels, the survey heard.
About 15 minutes later, two friends walked across the roof to see if they could find a workplace.
The survey heard them turn around and saw that Mr. Callum seemed to think they were on a lower level, beyond one level on the roof.
“Unfortunately, the roof level wasn't there. Harry fell to the ground below,” Norton said.
The two friends walked to the edge of the roof and saw Mr. Callum lying on the ground below, the question heard.
They rushed to Mr. Callum and realized he didn't respond.
One of his friends first arrived at Mr. Callum, calling 999, and the operator told him to start CPR.
He ran CPR until paramedics arrived and took over.
Despite their efforts, Callum was declared to have died at 4:40am, the investigation heard.
There are no health and safety violations, police say
A North Yorkshire police sergeant said there was a “proper safety railing” on the scaffolding, and the location is fenced with signs dictating pedestrians not to enter.
He said he was pleased with no health and safety violations from a construction site perspective.
Sergeant said it was concluded that Callum's death was not suspicious or involvement of third parties.
Toxicology reports found that Callum was twice the legal drink drive limit, the investigation heard.
Norton said that in the balance of probability, he was happy that Callum intended to “hop” from one roof to another “at a mansion that he had already done” when he fell to his death. I said that.
“(i) express my sincere pitiful dol to the family of both his family and his friend, Harry William Callum,” the coroner said.
