The father a missing 22-year-old slammed the family of the girl’s boyfriend, who returned alone from their cross-country trip and has now been named a person of interest in her disappearance.

Brian Laundrie’s family issued a four-line statement through an attorney, saying they hope Gabby “Petito is re-united with her family” but they intend to stay “in the background at this juncture and will have no further comment.”

“To be honest, that wasn’t a statement,” Joseph Petito said on “Crime Stories with Nancy Grace” on Wednesday. “That was four lines of crap. But what do I know?”

“If you honestly wish for her to come home already, then cool, let’s sit down and answer questions.”

Gabby Petito last spoke with her mother on August 23 or 24, CrimeOnline previously reported. Her father said he last spoke with her on August 21. Laundrie, 23, and Gabby started out on their trip earlier this summer. Her father said it was well planned.

She did it right,” he said. “She had an itinerary. She planned. She prepped. She did everything she was supposed to do.”

She spoke with family members several times a week, Joseph Petito said. And the family knew something was wrong when that stopped. They reported her missing on September 11. Laundrie returned home with the couple’s van on September 1. Laundrie has not answered questions has refused to respond to Gabby’s family.

Her father told Nancy Grace he doesn’t understand that.

“You’re gonna stay in the background? You just traveled the the country with this girl, and you’re gonna stay in the background,” he said. “Does anybody take that seriously? Do you think they care if she’s missing if they’re going to stay in the background?”

Petito decried the lack of response. “You can’t tell me you care. Not even a little bit,” he said.

Gabby was last seen in the Grand Tetons of Wyoming, he said, but he has no idea if that’s even close to where she might be. So he has a message for the Laundries.

“First and foremost, answer some questions. Are we in the right spot? Help us. At the end of the day, if I don’t have my daughter, it doesn’t matter. But they’re not helping.”

“And that’s the biggest issue right now,” he added. “The Laundries’ son is home in their house. And i don’t even know where to start looking.”
