I think jailing him during the proceedings is fitting because it ensures he is present.
You mean after he is extradited? He fled the country long ago.
I'd not be surprised to find out he's back in the US. especially if his marriage went further south.
He updated his info to a US P.O. Box and gave his us based cell phone number to the court. Yes he could have been using it in Bulgaria, but why not just include it the last time?
