Last year, my boyfriend was taken to the police station after an accident and was given a blood test for DUI. We had been waiting for the court date, but never received anything or heard anything since then. Is there a way to find out the status of this without having to pay for a lawyer? Since we never received a summons, I am a little worried. Shouldn't the summons come in certified mail? Since it has been so long, could he possible have a warrant for his arrest? We are in the state of Pennsylvania.
Thanks for the answers.

His license has the correct address and the officer came back to my house directly to return the insurance papers when he was at the station. I am sure they had the correct address. I have no idea what could have happened.
