(AP) - An airman at Dyess Air Force Base is set to appear at a military hearing related to the case of an Abilene toddler who died from dehydration and malnutrition. Senior Airman Christopher Perez is charged with child endangerment, failure to report child abuse and adultery. Perez allegedly was dating the toddler's mother, Tiffany Klapheke, who claims she neglected her children because she was distraught over her husband's military deployment. Her 22-month-old daughter died in August after being found unresponsive at their home at Dyess. The preliminary autopsy report says the toddler had chemical burns from human waste. Klapheke, a civilian, is charged with three counts of injury to a child. Evidence will be presented at the Article 32 hearing to determine if Perez should go to trial.
