In March 2018, Stacey Esterly’s husband, Kevin, made headlines when an AMBER Alert was issued for 16-year-old Amy Yu.

Stacey says she and Kevin considered Amy to be a “fifth daughter,” and although she claims she saw some unusual communication between her husband and Amy, she never imagined anything like this would happen.
