side of the sixth floor just before President Kennedy's motorcade, "leaving the whole scene in disarray, with stock shifted as far as the east wall, and stacks in between piled unusually high." Lee Harvey Oswald was working as a temporary employee at the building, and fired three shots from a sixth floor window at the presidential motorcade on November 22, 1963. Second building The Texas School Book Depository Company maintained a second warehouse at 1917 Houston, several blocks north of the main building. The short four-story structure was well removed from the parade route, half-hidden on an unpaved section of Houston. Oswald's supervisor Roy Truly told the Warren Commission that he had the option to assign Oswald to either building on his first day at work. "Oswald and another fellow reported for work on the same day [October 15] and I needed one of them for the depository building. I picked Oswald." This second building was eventually destroyed to make way for the Woodall Rodgers Freeway. Later years During his two terms as mayor of Dallas, Wes Wise guided Dallas out from under the cloud of the assassination and at the same time saved the Texas School Book Depository from imminent destruction, preserving it for further research into the president's murder. The Texas School Book Depository Company moved out in 1970 and the building was sold at auction to Aubrey Mayhew, a Nashville, Tennessee music producer and collector of Kennedy memorabilia, by the owner D.

After renovating the lower five floors of the building for use as county government offices, the Dallas County Administration Building was dedicated on March 29, 1981. On President's Day 1989, the sixth floor opened to the public (for an admission charge) as the Sixth Floor Museum of assassination-related exhibits. On President's Day 2002, the seventh-floor gallery opened. The gallery opened on February 18, 2002 with the exhibit: "The Pulitzer Prize Photographs: Capture the Moment". A $2.5 million renovation turned the storage area on the seventh floor into a new gallery space for the museum. Other exhibits that have hung in the space include works of Andy Warhol. On May 4, 2010, burglars attempted to steal a safe from the Sixth Floor Museum, but fled when "they were confronted by a security guard," leaving the
