In 2008, Adam's adopted sister alerted the Missing Children Hotline in Wichita that he was missing. Adam's adoptive parents told police that he had a history of running away, and in 1999, he ran away and never came back. Family members confirm that prior to his disappearance, Adam was often kept locked in a bathroom and spanked with a metal belt buckle. Foul play is strongly suspected with his adoptive parents as the main suspects.
