An Amish man who sent more than 600 text messages that included lewd images to a 12-year-old girl he randomly dialed was arrested when he arrived in his horse and buggy for what he thought was a meeting for sex, police said.

Willard Yoder, 26, faces four counts of child solicitation after being arrested June 15 in his hometown of Milroy, Indiana, about 45 miles (72 kilometers) southeast of Indianapolis. A not guilty plea was entered on his behalf during his initial hearing Friday.

Connersville police Detective Craig Pennington said authorities set up the meeting after the girl's mother alerted them her daughter was getting text messages from someone she didn't know.

The Amish are a conservative Christian sect that is known for simple living, plain dress and a rejection of most modern technology.

Jerry Beasley, director of the Menno-Hof, a nonprofit information center in Shipshewana in northern Indiana that teaches visitors about the Amish and Mennonite, said it's unusual for Amish to use either cellphones or landlines in their homes, but some do use community phones. They also have phones at their businesses and use cellphones for business, he said.

Pennington said that after the girl started getting the texts, she turned her cellphone over to her mother and the mother acted as if she were the girl.

"The mother made sure this person understood that this girl was 12 years old," Pennington said.

Pennington said the messages started out innocently, but eventually the man texting wrote that he was a 21-year-old Amish man named Willard and asked the girl to send naked pictures of herself and asked if she wanted to "make out."

Pennington said the man continued to send texts and the mother turned the cellphone over to police.

Pennington said Yoder also sent five pictures and two videos to the girl's cellphone, some of which included naked photos of him. Police then used the cellphone to set up the meeting.

Pennington said Yoder confessed to the sending the video messages, naked pictures and lewd text messages. Yoder told police he randomly dialed the girl's number.

"He says he just punched in the number hoping to have a conversation with someone," he said. "He said it was random. Everything else he said seemed to be true. But I'll find out more after his phone is forensically examined."

Yoder was released on a $20,000 bond on June 17. The horse and buggy were released to Yoder's family.

Court records don't list an attorney for Yoder. He is scheduled to appear in court July 1 with an attorney.
