A Colorado father has broken his silence, more than a year after his teenage daughter and two friends boarded a plane to the middle east intending to join ISIS. In an exclusive interview with Denver7 Investigator Tony Kovaleski, the father said he learned the terrorist organization recruited his then-15-year-old daughter and two of her friends on social media for more than a year before they boarded a plane from Denver International Airport bound for Turkey. The father reported their plan to the FBI and law enforcement intercepted the trio on a layover in Germany. "This is my little daughter going to join ISIS," the father told Kovaleski. "That's just the worst thing you can think about."
