Rpietilä has succumbed to road accident on the 14th of august 2020.
Source? Link or it did not happen.
His facebook says "Remembering Risto Pietila", which takes an obituary.

There isn't much under his name on Google but somebody did make a Wikipedia page for him in Finnish, after his apparent death.
