Two California nuns who stole around $500,000 dollars from the school where they worked and splashed out on travel and gambling in Las Vegas are facing criminal charges, their order confirmed Tuesday. Sisters Mary Margaret Kreuper and Lana Chang, who are said to be best friends, reportedly embezzled the huge sum over the course of a decade from St James Catholic School in Torrance, south of Los Angeles. The Archdiocese of Los Angeles said the money was discovered missing during a routine audit after Kreuper, who was principal at the school for 29 years, retired earlier this year.
