Jamie Gilroy, well-known nationally as the founder of the Wickerman Festival, died on Friday in hospital after an incident allegedly involving a firearm.
Mr Gilroy, who was married to Dumfries and Galloway Councillor Patsy Gilroy, was found badly injured in the head at his home, East Kirkcarswell farm, near Dundrennan, Kirkcudbrightshire on Thursday.
Police Scotland are investigating, but said they were not looking for anyone else in connection with the incident.
In a statement, Mr Gilroy’s family said: “’It is with immense sadness that we confirm Jamie’s death.
“This has come as a huge shock to us, to his many friends, and to members of the local and wider festival community in which he played such a vibrant part.
“We’d like to thank everyone for their support at this very difficult time.”
Mr Gilroy was a co-founder of the ultra-successful Wickerman Music Festival and mid-summer event has been held at his farm for the past 13 years.
