@x 7: "Is that because the extradition to the USA could be deemed illegal, so he's been put in a USA territory outside the regular legal system?"
Take off your tinfoil hat - Guam is a US territory, and isn't "outside the regular legal system". It would have been the closest US soil to the Maldives, so it makes sense that he would have been held on remand there while charges were prepared.
An extradition treaty isn't necessary; two countries can still agree to hand over a person without one.
Fuck him, I hope he enjoys his 27 years in federal prison. These weren't victimless crimes - he ruined the lives of a lot of small business owners.
