In April 1968, "The New York Times"—using Telfer as a main source—introduced the XYY genetic condition to the general public in a three-part series on consecutive days that began with a Sunday front-page story about the planned use of the condition as a mitigating factor in two murder trials in Paris and Melbourne—and falsely reported that Richard Speck was an XYY male and that the condition would be used in an appeal of his murder conviction. The series was echoed the following week by articles—again using Telfer as a main source—in "Time" and "Newsweek", and six months later in "The New York Times Magazine".
