A Tayside mum returned from a hair appointment to find her youngest son lying dead in the house they shared.
Michael Cuthbert, 35, died suddenly in the Friarton area of Perth.
His death is being treated as unexplained and Michael’s body has not yet been released for burial.
A report has been sent to the procurator fiscal.
Now his heartbroken family – who claim that Michael was worried he had heart trouble – are seeking answers.
His mum, Patricia, 61, said that her much-loved son’s death was her “worst nightmare” and she didn’t know what she was going to do without him.
She said: “He was my best friend – I am really going to miss him so much.”
Patricia said that on the day Michael died she had left the house just after noon to go to the hairdresser.
She said: “I was meant to be meeting him at 3pm but he didn’t turn up.
“I tried calling his number but couldn’t get a response.
“I knew something was wrong and I hurried home.
“When I got there he was lying on the floor. I tried to rouse him but I think he had already gone.
“I dialled 999 and an ambulance with paramedics arrived.
“While I was waiting for them, a woman tried to talk me through what to do but I couldn’t move him – he was too heavy.
“When the paramedics arrived they did everything they could but Michael was gone. I’m absolutely heartbroken. I’m going to miss him so much.”
Patricia added: “I had to identify his body which was awful.
“His body remains with the police and we have been told it won’t be released for about two weeks.
“I desperately want answers. I want to know how my son died and to be able to bury him.”
Michael was born in Dundee and attended St John’s Academy in Perth.
He lived in England for a while where he completed a mechanics course before travelling back north to stay in Perth.
His brother, Frankie, 39, said that Michael had been in and out of hospital with concerns about his heart.
Frankie said: “Michael believed something was wrong with his heart and he had various tests and scans over the years.
“However, the hospital kept sending him home and nothing was ever diagnosed.
“He was on a methadone programme but he was desperate to come off it.
“He was trying really hard to get completely clean.”
Frankie said that his younger brother would have done anything for anyone.
He said: “He was loved by so many people.
“I have literally had thousands of messages of condolence since he passed away.
“When we were boys we fought like cat and dog.
“Michael was wild but he was my best mate.
“He was a talented and skilled footballer and rugby player and he loved sport.
“At one time he was even being watched by football scouts.”
Michael’s other brother, Stephen Munro, 43, who travelled from England following his death, said the family were now waiting for answers.
A Police Scotland spokesman said: “We attended at Drummond Crescent, Perth, following the sudden death of a 35-year-old man.
“The death is being treated as unexplained and a report will be sent to the procurator fiscal.”
