KUALA LUMPUR, Malaysia (AP) — A court has sentenced former Malaysian Prime Minister Najib Razak to serve 12 years in prison after finding him guilty in the first of several corruption trials linked to the multibillion-dollar looting of a state investment fund that brought down his government two years ago. Najib was calm and stone-faced as he became the first Malaysian leader to be convicted. He has vowed to appeal the verdict. The judge sentenced him to 12 years in jail on one count of abuse of power, 10 years each for three counts of criminal breach of trust, and 10 years each for three counts of money laundering. The sentences are to run concurrently, meaning Najib faces 12 years in jail.
