My girlfriend pressed domestic charges on me and dropped my clothing and personal effects at the police dept. I've tried to have someone pick them up but there is an active warrant so they say that nobody but me can pick these items up
What is the name of your state, April?
If you know there is a warrant out for your arrest, you can be arrested at any time. It is generally better to turn yourself in to the police before that happens.
Before you are arrested or before you turn yourself in, you would be smart to hire an attorney. If arrested on the warrant and jailed, it can be harder to find an attorney so jail time might be longer (especially if arrested on a weekend).
You will want this attorney to not only help you with the warrant but also help in your defense to the domestic violence charges.
Good luck.
