Gabby Petito's anguished family went on "60 Minutes Australia" and pleaded for her fiancé to turn himself in as dogs in Florida assisted in the massive manhunt for him last week.
"He went home, he’s hiding. He used her credit card," said Petito’s mother, Nichole Schmidt, according to a sneak peak of the interview scheduled to air Sunday.
"Either way you look at, he’s a coward," said her father Joe Petito.
