Writer missing

At the Write4Gold Budapest and the Write4Gold Vienna there’s been a hungarian private detective around. We asked him whats up and why he is visiting the events. He told us he is looking for a hungarian writer who is dissappeared since more then 3 months. The parents of the hungarian boy have a big cause of concern since february. He never turned back from a trip to amsterdam in february. In a train from vienna to bucharest (via budapest) the police found his ID card and personal stuff so the anxiety of the parents is very serious and they call the european graffiti scene for help. If you saw the guy (photo above) or met him somewhere please send us an email, any help is very appreciated and needful.
Who met Nagy Miklos from Budapest (Hungary)?

Thanks for your time,
