Amber Alert Issued in Mexico For Missing Lehigh Valley Teen

Allentown police acknowledged Friday that they are now concentrating on tips related to Mexico.

A 16-year-old girl and a 45-year-old man missing from the Lehigh Valley since March 5 are believed to have taken a one-way flight from Philadelphia to Cancun, Mexico, according to Allentown police.

The new detail from police Friday comes one day after an Amber Alert was issued in Mexico Thursday for Amy Yu, who investigators now believe to have willingly disappeared with Kevin Esterly, a father of two.

On Thursday, an Amber Alert issued in Mexico read in part, "From the investigations, it’s determined that she might be traveling in national territory accompanied by ESTERLY, KEVIN MICHAEL. We consider the teenager’s integrity is at risk being that she could be a victim of a crime."

Allentown police acknowledged Friday that they are now concentrating on tips related to Mexico.

According to a warrant issued after the two disappeared, Esterly signed Yu out of school 10 times between Nov. 13 and Feb. 9 without her parents' permission.

Investigators said it now appears that the girl may have added Esterly to her school emergency contact list as a stepfather. That, they said, would have allowed him to remove the girl from school.

Esterly and Yu apparently had a secret relationship for months, and investigators said Yu may even have gone on family vacations with Esterly. He is married with two children.

Police said Yu's mother called Feb. 9 to report Esterly had signed her child out of Lehigh Valley Academy earlier that day.

On Feb. 15, records show police told Esterly to stay away from the teen's home.

Esterly may be driving a 1999 two-door, red Honda Accord with the license plate KLT-0529. Anyone with information about either person's whereabouts should call Allentown police at 610-437-7751 or by dialing 911.
