Gadi Dechter, who writes the City Paper's biweekly Media Circus column, found several examples of similar language between Michael Olesker's columns in the Baltimore Sun and work by other writers in the Sun, the New York Times and the Washingon Post. Dechter decided to pursue the story after a Dec. 24 correction of an Olesker column referred to a failure of attribution rather than plagiarism. The Sun's city editor initially told Dechter that there would be no further investigation of Olesker, so Dechter and a research assistant took on the process of checking language from Olesker's past columns against the LexisNexis database. "There was something unusual in the correction, as if it were just a mistake," Dechter says. "Olesker is kind of an institution here in Baltimore, so I set about checking it out." A story in the Sun this morning announced that Olesker had resigned.
