The former governor of the Mexican border state of Tamaulipas was caught Sunday in Italy, and both Mexico and the US want him extradited.
Italy can choose which country to send Tomas Yarrington to. In a joint statement today, both countries say they are "working together on a legal strategy which will allow Tomas Yarrington to face justice in both countries."
Suspects can be tried in one country and immediately sent for trial in the other, before serving any sentences in either.
