John Howland Wood Jr. (March 31, 1916 – May 29, 1979) was an American lawyer and judge from Texas. He served as a United States district judge of the United States District Court for the Western District of Texas before being assassinated by contract killer Charles Harrelson outside Wood's home in San Antonio, in 1979. Wood's killing was the first assassination of a federal judge in the 20th century.
Ben Thompson (November 2, 1843 – March 11, 1884) was a gunman, gambler, and sometimes lawman of the Old West. He was a contemporary of "Buffalo" Bill Cody, Bat Masterson, John Wesley Hardin, and "Wild Bill" Hickok, some of whom considered him a friend, others an enemy. Thompson fought for the Confederacy during the Civil War, and later for Emperor Maximilian in Mexico. After he was hired in 1881 as marshal in Austin, Texas, the crime rate reportedly dropped sharply. Thompson was murdered at the age of 40 in San Antonio, Texas, in the "Vaudeville Theater Ambush."
