A former priest who left the St. Louis Archdiocese more than seven years ago has been sued by a south St. Louis County resident who accuses him of sexual misconduct in the 1980s. The Reverend Robert Yim is accused in a lawsuit filed by a person only identified as John Doe 73. The plaintiff was a grade-school boy at St. Paul Catholic School in Fenton at the time of the alleged abuse. Yim left the Archdiocese and joined the United Church of Christ.
