+ism - missing type designer information

Hello community, I am looking for further information and the status of type designer Matius Gerardo Grieck, graphic/type designer responsible for the +ism foundry in the late 1990s and early 2000s.

Apart from basic information listed on Luc Devroye's depository there seems to be little to none other info – except for a lawsuit he filed against a TV Network in 2012. His fonts were once published on T-26 and Myfonts but have been discontinued.

See his profile here: https://luc.devroye.org/fonts-24426.html

I am interested in completing/reviving one of his lost designs that I could save from reference backups from 20 years ago, but can't seem to find any usable contact information.
