Mystery although it has since reverted to its original title, which mainly presents "true crime" documentaries. On nights except Sundays where live primetime breaking news coverage from CBS News occurs, the timeslot of that coverage is branded as a special edition of 48 Hours, but is not part of the Saturday program's yearly ratings average and has little to no involvement from dedicated members of the 48 Hours production and on-air staff. In 2009, the program featured interviews with Jodi Arias concerning the murder of her former boyfriend, Travis Alexander. These recordings were later used in 2011 as evidence in court to convict Arias, the first time the program's interviews had ever been used in a death penalty trial. On September 17, 2011, 48 Hours began broadcasting in high definition, making it the last prime time newsmagazine on U.S. broadcast television to convert to the format. Variations 48 Hours Investigates/Mystery The program was revamped in 2002, when Lesley Stahl took over hosting duties from Dan Rather, and its title was changed to 48 Hours Investigates. The title was changed again to 48 Hours Mystery in 2004, and with its single-topic format, it does not use a single host but is narrated by the reporter assigned to the story. The current format of the documentary primarily deals with real-life mysteries and crime stories, again with just one mystery per episode (such as the murder of Brian Stidham), owing to its heritage structure of featuring a single topic per episode. The program is not confined to reporting mysteries; CBS often uses the 48 Hours title or timeslot to present mainly special reports on breaking news events only scheduled on the same day, such as a 2006 report on the fifth anniversary of the September 11, 2001 attacks, coverage of the Virginia Tech massacre in April 2007 or coverage of the Sandy Hook Elementary School shooting in December 2012. However, the relationship between these special programs and the rest of the program's editions are essentially limited to the program's title. 48 Hours: Live To Tell 48 Hours: Live To Tell uses a different format from the earlier versions of the program. This format does not utilize a narrator; instead the stories are recounted entirely by the victims and those who know the victims of crimes; some episodes also focus on other life-threatening situations, but are recounted in the same manner. 48 Hours: NCIS
