Allentown police issued a missing person alert Wednesday for Kevin Esterly and Amy Yu. A warrant for Esterly's arrest for interference with the custody of a child also was issued Wednesday, according to the Allentown Morning Call.
Amy's mother called police on Feb. 9 to report Esterly had signed her child out of Lehigh Valley Academy earlier that day without permission, according to court documents obtained by the newspaper.
The mother called police again on Feb. 15, and officers arrived to tell Esterly and his wife, Stacey, to stay away from the family's home. It wasn't clear in the court records why the couple were there.
Police interviewed the teen a few days later, and she told them Esterly had signed her out of school about five times. However, investigators checked the Bethlehem charter school's records and found Esterly signed Amy out of school 10 times between Nov. 13 and Feb. 9 without her parents' permission.
Susan Mauser, CEO of the International Baccalaureate school, said protocol is that only guardians or emergency contacts can pick up students in grades K-12. She couldn't say whether Esterly was listed as an emergency contact for the teen.
The school is making sure all protocols were followed and are working with police to provide whatever they need in their investigation, she said.
"We just really hope she returns to her family soon," she said.
On Monday, Amy's mother reported her as a runaway. Police contacted Stacey Esterly, who told them she last saw her husband at 6 a.m. that day and that he'd taken personal documents and withdrawn $4,000 from her account. No phone number could be found for the Esterlys.
Police say Amy and Kevin Esterly, who works as a concrete contractor, had a "secretive relationship." They were last seen Monday near Amy's parent's home in Allentown and might be in Esterly's 1999 red Honda Accord.
