U.S. Marshals in Plano, Texas, and Lafayette, La., are joining forces in tracking down 28-year-old Michael Gary Blasingame. They say Blasingame fled the United States with his then-18-month-old son, Eitan, instead of complying with the custody agreement he shared with Eitan's mother, Diana Huynh. It's been a frustrating two years for Diana and for U.S. Marshals, who believe Eitan is in danger.
