No internet or shared public information on criminal backgrounds, but vocation directors in the 1980's did ask probing questions about personal history, faith formation, sacraments, church attendance, family, schooling, sexual history, dating, employment etc. during the interview process.  These also came up during the course of hours and hours of spiritual direction in seminary.  If he simply chose to withhold this information from those charged with his admission to seminary and formation, there is a problem because those who called him to holy orders were grossly deceived. To put it another way, his past might well have proven to be an insurmountable impediment to ordination which raises the question: Did his ordaining bishop know about his past and elect to ordain him anyway?
