Dallas (WBAP/KLIF) – The Jesuit College Preparatory School of Dallas has been sued by another former student who claims he was sexually assaulted by a priest while attending the school in the 1980’s. The lawsuit alleges the unidentified former student was abused by the Rev. Patrick Koch. It also claims the Dallas diocese covered up the abuse. The diocese does have Koch on a list of clergy “credibly accused” of sexually abusing children. Koch was never charged with a crime, and died in 2006 at age 78.
