Guatemala's former police chief Erwin Sperisen on Friday received a life sentence in Switzerland for seven murders committed in the Central American country.
Sperisen, 43, holds Swiss and Guatemalan citizenship and, having left his homeland for Geneva, could not be extradited to stand trial for murdering prisoners in the mid-2000s.
But under Swiss law, any citizen of the Alpine country can be tried at home for crimes committed abroad.
