For all the tumult and anguish he has caused to two families he should be executed in a painful way. Unfortunately no death penalty in Peru unless a prison murder is arranged by the father of the Peruvian lady he killed.
I rather hope they DON'T have the death penalty in this case. Because I hear the Peruvian prisons are far from pleasant. I'd like to think of him spending endless hours of endless days of decades there...and hopefully, never again see the light of freedom.
