I got a voice mail from a male claiming to be a detective and saying I have five pending cases of assault and that he put out a warrant for arrest. He did not say what department he was from and just said call the number back that you see on your caller ID. I called the number back and a automated voice comes saying say your name and then the phone rings but no one answers the phone. I found out that this number is a google voice and the area code is 772 and I don't even live in Florida.

This is a known scam in these pages.  He will make those "charges" go away for a price.  This is also known as bribing a police officer (not that he really is a police officer, but if he was).  Which is a crime in itself.  If you had committed crimes and the police knew your name, they would come and pick you up, not call you and warn you.

Print out a copy of this page and go to your local police department.   There is an ongoing scam whereby someone pretends to be a real detective in a local police force  and engages in threatening statements basically telling you bad things will happen to you unless you pay him money.

He calls you again, tell him you KNOW this is a scam and that you are going to the local police department to make a complaint of extortion.

Assault cases and any other crime would be handled by your local police department and an investigator would talk to you in person.   You'd know about it from local law enforcement.   You would not hear about if from someone out of state.
Total scam.  Don't fall for it.
