FEASTERVILLE, BUCKS COUNTY (WBRE/WYOU) Jen Betz says it’s what she saw a stone’s throw from her home that prompted her to call Pennsylvania’s Child Line.

“You notice these little children, these little girls, only little girls and they be outside rarely, sporadically, you’d see one or two,” Jen Betz said.

This mother’s complaint has uncovered deeply disturbing case. Police on Thursday removed 12 girls, including an infant, they say were living in a house in the 400 block of Old Street Road in Feasterville.

The children had no birth certificates, and weren’t enrolled in any school. It’s alleged – Lee Kaplan- was gifted the oldest of the girls by her own parents, who live in Pennsylvania’s Amish Country.

Today, she is 18 years old and they say Kaplan began a sexual relationship with her starting when she was 14. Police say she gave birth to two of Kaplan’s children.

“Mr. Kaplan had her living there as some kind of repayment for a financial situation,” Lt. John Krimmel of Lower Southhampton Police said.

News of the charges and allegations sent shockwaves through the community.

“We are flabbergasted, we are amazed this is all going on…. And nobody knew,” neighbor Irene Guille said.

“Just amazed, been going on right under our noses,” neighbor Chris Schwab said.

“I thought they were just part of his family,” neighbor Barbara Heckman said.

Police have also charged the couple to be the mother and father to ten of the girls. Arrest papers reveal David and Sevilla Stoltzfus knew their daughter, starting at 14 years old was engaged in a sexual relationship with Kaplan.

Neighbors say they were often curious about the living arrangements in the home.

Some call Jen Betz the hero of the story, she calls it motherly instinct.

“I just made the call. I don’t know, just an instinct. I just feel like I wasn’t going through another summer, where everybody should be outside and I not see those little girls out again,” Betz said.
