Matthijs didn't have it easy as a kid, he grew up in a poor neighboorhood in Arnhem and turned to a life of crime at the age of 14, he started dealing drugs at his school and was eventually caught and send to a Youth Detention Center in Amsterdam. The smart guy that he is decided to act by their rules and behaved properly, resulting in his release 3 years later. He continued dealing drugs for another year before moving to Amsterdam. After moving there he got into contact with some Irish lads and started smuggling weapons by car from Ireland across Britain and the channel back to Amsterdam. After bringing the weapons back home he sold them to the Moroccan Mafia for large profits. He continued to do so for a couple of years and his relations with the Irish improved greatly. They told him they would go to Chernarus to get a hold of more weapons and could use his help. So he decided to go with them.
