In a recording first obtained by FOX News, a person tells the dispatcher that he saw a man “slapping the girl.”
The caller goes on to say, “They ran up and down the sidewalk. He proceeded to hit her, hopped in the car and they drove off.”
The incident happened Aug. 12 in Moab, Utah, while Gabby Petito and her fiance Brian Laundrie were on their road trip. A fight between the couple reportedly turned physical outside a Moab grocery store.
Someone called the police, who caught up with the couple’s van near the entrance to Arches National Park. Officers said they spotted the van going 45 mph in a 15 mph zone.
Last week, the police department released body camera footage of that stop. Petito appeared emotionally distraught and told officers that the two had been arguing during the day.
While the 911 caller reported a man hitting a woman, Petito did not report that Laundrie struck her during the traffic stop, according to police.
Laundrie, who had visible marks on his face, told police that Petito had “gone into a manic state” after thinking that he was “going to leave her in Moab without a ride” and slapped him repeatedly before scratching him when he tried to push her away.
The incident happened just weeks before Petito was reported missing.
On Sunday, authorities announced they found remains in Wyoming believed to be those of the 22-year-old.
A search continues for Laundrie, 23, who authorities said is a person of interest in the case.
The FBI was seen at his family’s Florida home Monday.
