The first page of the Contra Costa Times Web site this afternoon was blunt in announcing the departure of the paper’s editor, Chris Lopez. “Editor of Times replaced,” the headline said. Not something you would expect, like “Editor resigns.” Publisher John Armstrong said in an internal memo that Lopez is being replaced because his position had become “redundant.” On Aug. 11, nine days after MediaNews bought the Times, ANG Newspapers executive editor Kevin Keane was appointed to oversee Lopez, creating a situation where the paper essentially had two editors. Yesterday, less than three months after that move, MediaNews decided it could get by with just one editor — Keane. Lopez has been at the Coco Times since 2000, starting as an assistant managing editor, then ME and then executive editor. Previously he was at the Denver Post, where he was part of the team that won a Pulitzer in 1999 for coverage of the Columbine High School shootings.
