This particular type of crime, yes, I think extradition is appropriate. Basically, any type of crime where someone has been injured or killed, should definitely be extraditable. But the burden of proof has to be upon the country in which the crime occurred. Whether the act is a crime in the country in which the suspect has taken refuge should have no bearing on the case, in most instances. Although I can think of some cases where that might be a factor. The potential punishment for the crime should also be considered. A possible death penalty can be grounds for withholding extradition.
