its branding from "Fox 24" to "Fox Kansas," in order to help position KSAS and its satellites as a regional "network" along the lines of the other major stations in the market (such as the Kansas State Network, the Kansas Broadcasting System, and the KAKEland Television Network). Two years later, KBDK (channel 14, now KOCW) in Hoisington was added as another full-power satellite to serve Great Bend and Hays. The Wichita-Hutchinson market's four major network stations all require at least three full-power transmitters to cover the unusually large market, which covers over 70 counties stretching from the Flint Hills to the Colorado border (encompassing almost three-fourths of the state), making it the largest designated market area (DMA) by number of counties in the United States. In 2005, KSAS became a crucial location in the search for and apprehension of infamous Wichita serial killer Dennis Rader, known for decades as the anonymous BTK Killer. Rader's last known communication with the media and police was a padded envelope which arrived at KSAS' West Street studios (one of many stations in the Wichita market which Rader had contacted over the years) on February 16 of that year. Enclosed in the package was a purple, 1.44-MB Memorex floppy disk; a letter; a photocopy of the cover of a 1989 novel about a serial killer (Rules of Prey); and a gold-colored necklace with a large medallion. Police found metadata embedded in a Microsoft Word document on the disk that pointed to Wichita's Christ Lutheran Church and the document was marked as last modified by "Dennis". A search of the church website turned up Dennis Rader as president of the congregation council. On April 20, 2007, Clear Channel entered into an agreement to sell its television stations (including KSAS and its LMA with KMTW) to Newport Television, a holding company owned by private equity firm Providence Equity Partners; the deal closed on March 14, 2008. Longtime Wichita television broadcaster Sandy DiPasquale, the group's president and CEO, was part owner of Smith Broadcasting, and was the last local owner of CBS affiliate KWCH-TV from 1989 to 1994. DiPasquale moved Newport's headquarters to Kansas City in 2008 from his longtime base in Wichita. On July 19, 2012, Newport Television announced the sale of KSAS-TV to the Sinclair Broadcast Group as part of a group deal worth an estimated total of $1 billion involving the sale of 22 stations
