On July 27, 1953, the U.S., North Korea, South Korea and China agree to an armistice that brings about an end to the Korean War. The armistice created a demilitarized zone between the two Koreas, and gave South Korea slightly more land than it had when the conflict began in June, 1950. On July 27, 1974, the House Judiciary Committee recommends President Richard M. Nixon be impeached on the charge of obstruction of justice in attempting to impede the investigation of the break-in at the Democratic Party national headquarters in the Watergate Complex in Washington. Charges of abuse of power and contempt of Congress will be approved later in the week. On July 27, 1981, 6-year old Adam Walsh is abducted from a mall in Hollywood, FL. His severed head would be found in a drainage canal 100 miles away two weeks later; the rest of his body is never found. Over the next decade, career criminal Ottis Toole would confess and recant on the crime repeatedly from his Death Row cell (from another case), until his death from AIDS in 1996. It wasn't until 2008 that police would say they had found enough evidence to pin the murder on Toole. In the wake of his son's death, John Walsh would co-found the National Center for Missing and Exploited Children. He also left his career as a hotel developer and became a TV producer, developing several crime-based programs, most notably America's Most Wanted, which ran for 25 years. In 1994, the Wal Mart chain introduced "Code Adam," a lock down and search procedure in the event a child goes missing in one of their stores. Many other national and regional store chains have copied the procedure.
