In March 2018, Kevin Esterly was arrested and charged with interfering with the custody of a child when it was discovered that he ran away from Pennsylvania to Mexico with his daughter’s 16-year-old best friend, Amy Yu. According to police, the father of four had been carrying on a secret relationship with Yu, whom he considered to be a “fifth” daughter, for months.

TELL DR. PHIL YOUR STORY: Have a story in the news?

Esterly’s estranged wife, Stacey, claims that in the months leading up to Kevin and Amy’s trip, she noticed some unusual behavior between her husband and the teen, who called the couple “Mom” and “Dad,” but she says she never suspected the two were involved in a relationship.

Stacey, who says she’s filed for divorce, recalls the first conversation she had with her husband since he’s been in jail.

“He said, 'Thank you for accepting my call,'” Stacey tells Dr. Phil in an exclusive interview airing Thursday. “He never once apologized, never once, you know, said he was sorry. All he said was when he gets out he’ll explain the whole story.”
