In the meantime, that incredible scene overnight. Those two amish girls returning home a day after they were abducted from their family's roadside vegetable stand police searching for the suspect and ABC's gio Benitez has been on the scene live in upstate new York. Gio. Reporter: David, good morning to you. We are just miles from Canada and that is what had so many people here worried sick that these girls would be taken across that border but right now that headline found alive. This morning a manhunt is under way for the person or persons police believe abducted two amish girls before mysteriously letting them go overnight. There's still an active criminal investigation here because somebody still took these children away from their home. Reporter: 6-year-old Delila miller and her 12-year-old sister Fannie now back home with their family after a frantic day-long search around New York. They're cold. They were wet. They are talking to the FBI and the sheriff's department right now. Reporter: It all started Wednesday night. The two girls were working their family's vegetable stand when police say a red four-door sedan pulled up. By the time it drove off, the girls were gone. Their parents who do not have a phone running to a neighbor's house to alert police. Investigators forced to work with only a sketch of the 12-year-old because many amish shun modern technology. They did not allow police to draw a sketch of the 6-year-old. Then late Thursday after the small town gathered for a prayer vigil, a breakthrough. Rescuers rushing to the family home after learning the girls were alive. Authorities tell us the alleged kidnapper dropped them off in the small town of richville, about 30 miles from their home. The girls walked up to a stranger's house. Thank goodness they had enough courage to be able to do that. Knocked on the door and that person took them home. Reporter: State senator patty Richie speaking with their father before their return home. He said it was in god's hands now and shortly after we came back from the prayer vigil we got good news so maybe Mr. Miller knew something the rest of us didn't. Reporter: And back here at the search command center we can tell you that last night when that good news came in there was so much applause coming out of this building here and more good news right now, we're told those two little girls appear to be healthy this morning.
