I understand that if you fail to show up for a court appearance that they issue a warrant for your arrest.Let's say the person decides to turn themselves in a year or sevaral years later... does this person face any additional consequences.

Scenario:

I was suppose to show up for court for weapons posession( a felony here in NYC)... however I decided not to show up for court because my fiancé was pregnant. ( there was no trial as of yet) Now I want to turn myself in... Somebody please help me!
