An unknown person is believed to have assisted a young man in taking a deadly shot of heroin, a court heard.
Adam Wells, 28, was found dead in his room at Poolsbrook Hotel, near Staveley, on April 5 last year.
Mr Wells – who was described by his family as a “loveable rogue” during an inquest at Chesterfield coroners’ court on Wednesday – was believed to have been using the drug for the first time.
Coroner James Newman told the hearing: “It’s highly unlikely that Mr Wells could have prepared the heroin and injected himself without some assistance.
“An unknown person would have been involved in the process of preparation and injection.”
The inquest heard Mr Wells and a friend, Daniel Banks, who was also staying at the hotel, had intended to go out in Chesterfield town centre.
Mr Banks knocked on Mr Wells’ door but there was no response.
The door was slightly ajar so Mr Banks pushed it open and found his friend unresponsive in the room.
Despite resuscitation attempts by Mr Banks and paramedics, Mr Wells was pronounced dead at about 2.20am.
PC Carl Davies, of Derbyshire police, said drugs paraphernalia – including an empty broken needle and a used needle – were found in Mr Wells’ room.
The officer said it was possible Mr Wells got the heroin from someone else at the hotel and added there may have been someone in his room when the drug was injected.
Items were also believed to have been taken from Mr Wells’ body after he died, the court heard.
Post-mortem reports showed Mr Wells had a single puncture mark on his arm.
Toxicological tests revealed he died of alcohol and heroin misuse.
Mr Newman recorded an open verdict, saying there were unanswered questions surrounding Mr Wells’ death.
He also warned: “It takes just one injection of heroin to kill.”
