A Tumblr blog collects testimonies [fr] of people who know a sexual predator. The “About” page of the site states that the goal is to show that rapists are not just psychopaths who are statistical outliers but people we know (80% of rape victims knew their aggressors). One contributor recalls one such tragic story [fr]:

He was 38 when he left for a village in Africa on a missionary journey. Everyone [back home] admired his work for the population. He came back 3 years later and no one know why. [..] I learned a year ago he reason he returned: He raped children there. He confessed to his crime but he is still free. [..] I hate how my parents and their friends try to find excuses for the horrors he committed.
