The parents of a Minnesota boy abducted 26 years ago say they have as many questions as everyone else after federal authorities identified a "person of interest" in the case.

Patty and Jerry Wetterling gave brief statements Tuesday outside their central Minnesota home, not far from where their 11-year-old son Jacob was abducted in 1989.

Last week, authorities identified 52-year-old Daniel James Heinrich as a "person of interest" in Jacob's disappearance, but refused to call him a suspect. They say Heinrich has denied involvement. He faces unrelated child pornography charges.

Patty Wetterling says the family will let the legal process continue and "watch impatiently for answers." She and her husband asked anyone with knowledge about the case to come forward.
