5 became the first television station in Texas to present all of its news film footage in color. In 1967, Fort Worth native Bob Schieffer began his broadcast career at WBAP-TV as a reporter and anchor of the station's 10:00 p.m. newscast. After leaving the station in 1971, Schieffer went on to Washington, D.C. to work as a reporter for independent station WTTG (now a Fox owned-and-operated station) and the now-defunct Metromedia news service, then embarked on a long career with CBS News that lasted until his retirement from full-time broadcasting in August 2015 and continued thereafter in a contributing role. In February 1970, WBAP-TV debuted the first locally produced television newsmagazine, Texas '70s, a monthly half-hour program showcasing feature reports focusing on the culture of Texas. On January 25, 1986, a KXAS news crew was assigned to cover a standoff started by 40-year-old Thomas E. Stephens, when he barricaded himself inside an Arlington 7-Eleven store where his estranged wife, Patricia (who filed divorce papers that Thomas was served with the day before), had managed. Believing she had initiated the idea of the divorce to Patricia, Thomas fatally shot her roommate and store clerk, Terry Palmer, and wounded fellow employee Craig Talley; Patricia later snuck out of the store's front door as Thomas talked to a hostage negotiator over the phone. Around 6:40 p.m., during an update on the standoff within the extended 6:00 p.m. newscast as a live shot outside the store was being shown, the videographer on-scene captured Thomas coming out and killing himself with a .357-caliber pistol, ending the seven-hour standoff. Weekend anchor Mike Snyder, who joined KXAS in 1980 and served as the main anchor of the weeknight newscasts from 1992 until he retired from broadcasting in 2013, issued an on-air apology to viewers for the live broadcast of the suicide. In 1989, KXAS became the first television station in Texas to implement closed captioning for its newscasts. In 1993, KXAS-TV launched the "Public Defenders", an investigative reporting unit (consisting of reporters Sabrina Smith, Mike Androvett, and Marty Griffin) that conducted investigations into businesses that have ripped off local consumers and uncovered various consumer scams as an ongoing segment during the 10:00 p.m. newscast until 1999. On March 28, 2000, the tower camera based in Sundance Square in Fort Worth caught footage of a multiple-vortex F3 tornado that struck the city's downtown area. Master control operators
