A Milroy man who police said showed up at an undercover sting in a horse-drawn buggy has been charged with soliciting a 12-year-old girl for sex.Willard Yoder, 21, who is Amish, sent 600 texts, nude pictures and videos to the girl, saying he wanted to have sex with her, Connersville police said.The girl's mother discovered the texts and went to police, who then set up a sting at a local restaurant.When Yoder arrived in his horse-drawn buggy to meet the girl, he was arrested on four counts of soliciting a minor, police said."We set up in our positions, and we heard the vehicle coming down the roadway," said Connersville police Detective Craig Pennington. "We thought, 'Well, this is obviously going to be it.'"Investigators said Yoder later confessed to sending the texts. He was released on bond.The girl's father, who didn't want to be identified, told 6News' Ericka Flye he was outraged by the messages."When the pictures started coming in, and they got more graphic, I was like, 'Oh my gosh, this is unbelievable," he said.The girl's father said he and his wife, acting as their daughter, kept communicating with Yoder."I thought police needed to handle it immediately or I would," he said.Police said that Yoder told them the sexting began when he sent out a random text and got a response."(He) started a new conversation with just a random text. So, that's kind of frightening, but it does happen," Pennington said.Even though the Amish typically shun any technology, Milroy residents said they are used to seeing Amish people with cellphones.Yoder is set to appear in court in September.
