VATICAN CITY – The Vatican is sending its top two sex crimes investigators to Mexico on a fact-finding and assistance mission as the Catholic hierarchy in the world's second-largest Catholic country begins to reckon with decades of clergy sex abuse and cover-up. Their new mission to Mexico, due to take place March 20-27, was announced Monday in Mexico and at the Vatican. In addition, two senators presented a legislative initiative to create an independent investigatory commission into clerical sex abuse in Mexico. The Legion scandal has resurfaced anew recently, with the Salazar case spurring other Legion victims to come forward. Earlier this year, a group of former Legion priests prepared a list of 30 Mexican Legion priests who were accused of abuse and presented it to the Vatican ambassador.
