A staff reporter for The New York Times committed frequent acts of journalistic fraud while covering significant news events in recent months, an investigation by Times journalists has found. The widespread fabrication and plagiarism represent a profound betrayal of trust and a low point in the 152-year history of the newspaper. The reporter, Jayson Blair, 27, misled readers and Times colleagues with dispatches that purported to be from Maryland, Texas and other states, when often he was far away, in New York. He fabricated comments. He concocted scenes. He lifted material from other newspapers and wire services. He selected details from photographs to create the impression he had been somewhere or seen someone, when he had not. - Ian Dexter Marquez
