Carmen Durso, an attorney who represented dozens of people who claimed they were sexually abused by Roman Catholic priests says there are at least several dozen more with similar claims against the Boston Archdiocese. Last year, the archdiocese reached an $85 million settlement with more than 550 people who said they were abused by priests. Durso represented 40 victims in that case. He is representing 12 people who allege they were molested from the 1950s to the 1980s.
