Regardless of what county in Florida that you are in, the way that arrest warrants work is the same. Because arrest warrants are extensions of the authority of the state of Florida, this means that you can be arrested no matter where you are within the state, and fleeing to a different county wont prevent that arrest form being made.
An arrest warrant can be created when, after a crime and investigation, police collect evidence and identify a likely suspect. Once this is done, the police appear in a court before a judge, and demonstrate their evidence. Provided that there is enough evidence to justify an arrest warrant meaning that it clearly implicates the individual in question he will sign and authorize an arrest warrant, which allows the police to arrest the suspect. A Monroe County FL arrest warrant is valid for 48 hours after being signed.
