After police appeals and facial reconstruction created by Liverpool John Moores University, officers can confirm the man was 61-year-old Ean Coutts who lived in the village of Kinglassie.
His remains were found at Whitehill Industrial Estate in Glenrothes in September, 2020.
His death was treated as suspicious, and on Tuesday, January 12, a 30-year old man was arrested in connection with the death and released pending further enquiries.
Detective Chief Inspector Kevin Houliston, from Police Scotland's Major Investigation Team, said: "We received a significant number of responses following release of the facial reconstruction and I would like to thank all those who contacted us.
“This has allowed us to identify the man as Ean Coutts and my thoughts are with his family at this time. Ean had lived in Kinglassie for a number of years and was well known in the village.
"We are treating his death as suspicious and officers will be carrying out enquiries in and around the Kinglassie and Glenrothes areas as part of our ongoing investigation.
“It Is vital that we establish the events leading up to his death to provide answers to his family.
"I am appealing to anyone who knew Ean, who may have had any contact with him from around August, 2019, and anyone who has information that could assist with our investigation to contact us as a matter of urgency.”
Anyone who can help is asked to call 101, quoting incident number 2692 of Sunday, 27 September, 2020.
