It sounds like a civil lawsuit was filed and the other party obtained a default judgment against you which would allow them to garnish your wages 6-years post accident. As mentioned by my colleague, find out from your dad, if he had insurance at time which covered the moped. If so, contact them ASAP. If not, get a copy of the civil complaint, default judgment and wage garnishment and bring them to a Las Vegas Avvo Attorney.
