A police probe into the death of Alva architect Colin Machin has found “no suspicious circumstances”.

The 50-year-old was found dead in a walk-in freezer at his home in Boll Farm, Brook Street, on 25 June.

Due to the bizarre nature of his discovery, police treated it as “unexplained” and immediately launched an investigation.

That concluded last week and the Advertiser understands that the tragedy is now being treated as suicide.

A Police Scotland spokesman said, “Enquiries have concluded and a report has been submitted to the procurator fiscal. There are no suspicious circumstances and we are not looking for anyone in connection with the death.” His funeral is due to take place at St Mungo’s RC Church in Alloa on Wednesday, 10 September at 12pm and then Alva Cemetery.

The Machin family have asked for only family flowers, but for donations to be made to Rachel House Children’s Hospice.

Colin left behind his wife, Maria, and daughters, Sinead (23) and Erin (21). His youngest daughter, Orla, who suffered from rare genetic condition Edwards’ Syndrome, regularly attended the hospice in Kinross for respite until her death in 2008 aged 10.

At the time of her father’s death, Erin paid tribute to him on her Facebook page with words from the Dougie MacLean song Caledonia.

She wrote, “Let me tell you that I love you. And I think about you all the time.” Colin was well-known in Clackmannanshire as architect and director of Machin Associates Limited and The Boll Holiday Cottages which he ran with Maria. Last year he co-founded award-winning architectural practice, Machin Dunn & MacFarlane Ltd, which was appointed to work on the redevelopment of the former Co-op site in Alloa. He was also a director with Edinburgh-based firm Tigh Grian Ltd which is due to start work on 48 social-rented homes at the former Alva Academy site.

In addition to his work as an architect, Colin was tourism rep on the board of Clackmannanshire Business and was known for his charitable work through the Rotary Club of Alloa which he joined in 1992 and served as president in 1999.
