Shannon's law is named after Shannon Smith, a fourteen-year-old Phoenix girl killed by a stray bullet in June 1999. Smith's parents, after being informed that the assailant's activity constituted, at most, a misdemeanor offense, advocated stronger penalties, to prevent future incidents of this kind.
Otis and Lory Smith joined the board of directors for Arizonans for Gun Safety. They started a campaign that took them all over Arizona. Their efforts were supported by councilman Phil Gordon, the city council of Tucson, and president of the National Rifle Association Charlton Heston. After a speech by Governor Jane Dee Hull voicing her support, senate minority leader Jack A. Brown named passing the law a priority. The Arizona legislature failed to pass the bill twice in 1999, but it finally received both state senate and state house approval in April 2000. The bill was enacted that July, with Governor Hull signing the bill in the Smiths front yard.
