Five tribes gathered at the Ak-Chin Indian Reservation in Arizona to celebrate National Missing Children's Day on May 25, 2011. More than 65 people, including federal, county, and municipal law enforcement officers, participated in the celebration and a two-day investigative training session. The Ak-Chin Tribe produced and showed a child abduction video, and the Tribe's youth council demonstrated dancing and constructed small adobe huts and native grass shelters for table centerpieces.
