A former plant worker received an eight-year prison sentence for committing wire fraud and cheating his employer out of nearly $500,000, the Department of Justice announced. 

The perpetrator, 57-year-old John Laakso — who also went by John Trebesch — reportedly worked as a contractor and later became an engineering manager at GAF Materials Corporation’s roofing factory in Savannah, Georgia. His responsibilities included securing equipment and services for the facility, which makes products for residential and commercial roofing applications.
