Sanchez is believed to have fled the state Illinois in August 2003, shortly after being charged with predatory criminal sexual assault, the release said. Police linked Sanchez to the sexual assaults of the three children.

Bond was arrested and initially held without bond in the case. But a judge later set a bond, and Sanchez was released. But he failed to appear at his next court hearing and has not been seen since, the FBI said.
