The answer is: It depends. Mostly it's dependent on the seriousness of the charge,
but also on the distance from the original jurisdiction holding the warrant.
Had a number of arrests where the defendant had some our or another 'local' jurisdiction,
along with a few from much further away; like in another state. When they finished either
paying the bond or serving the time out with us, the next closest was then contacted to
come pick them up. And for those further away, they had to then make the decision
on whether it was worth it for them to come and transport back. There were other times
that I'd come across someone with a valid warrant, but when the issuing agency was
contacted and inquiry made as to "do you want them?" They would say that it was
just too far away and the answer many times was: "Let 'em go." If there wasn't
anything that we had present charges on...... they caught a BIG BREAK and
were extremely thankful. I would usually recommend that they look into
taking care of that warrant a.s.a.p., because there could come a time
when the agency would 'change their mind' on the distance, or that
the person of interest would be back in the area of interest and
then something could happen to bring them back under the
scrutiny of law enforcement and then it would be too late.
Of course, it would seem that if that was the case (in the interest of 'fair play')
that those warrants should be wiped off the books.....but of course, they weren't.
Guess they hoped that the person of interest would swing back to their old stomping
grounds and then might slip up and be picked up "locally" 'again'.
To avoid such an occurrence from happening in the future, you might want your 'friend'
to contact the jurisdiction holding said warrant and arrange to get that thing taken care of......
some take payment plans depending on the seriousness of the charge(s).
