Can't he change his name ? Leave puntland and live on the low ?
Nope. His own family will turn on him. Puntlands military system is harsh and they have a good track record of punishing and even executing soldiers that misbehaved.
I don't think he will be executed because rape is not a reason for death penalty according to the laws. But he'll be imprisoned, flogged and will pay thousands of dollars to the victim. The fucktard brought disgrace to our heroes that keep Puntland safe.
