(Meredith/AP) -- Police released audio of a man calling 911 in August to report a "domestic dispute" between Gabby Petito and her fiancé, Brian Laundrie.
The man said he saw Laundrie slap Petito on the side of the road in Moab, Utah, on Aug. 12, according to a recording of the 911 call obtained from the Grand County Sheriff’s Office.
"We drove by, and the gentleman was slapping the girl," the caller told a 911 operator. "Then, we stopped. They ran up and down the sidewalk. He proceeded to hit her, hopped in the car, and they drove off."
Video released by the Moab Police Department showed an officer pulling the couple's van over on the same day after it was seen speeding and hitting a curb near Arches National Park. The body-camera footage also showed an upset Petito.
Laundrie said in the video that the couple had gotten into a scuffle after he climbed into the van with dirty feet. He said he did not want to pursue a domestic violence charge against Petito, who officers decided was the aggressor.
Moab police separated the couple for the night, with Laundrie checking into a motel and Petito remaining with the van.
In the footage, Gabby Petito cried as she told the officer that she and Laundrie had been arguing over her excessive cleaning of the van. She told the officer she has OCD — obsessive compulsive disorder.
On “Dr. Phil,” her father said that wasn’t literally true. She just likes to keep her living area orderly and was using slang, he said.
Weeks after the Utah incident and Petito's reported disappearance, the FBI announced that agents discovered human remains at a Wyoming national park that were "consistent with the description" of Petito. Authorities found the body Sunday on the edge of Grand Teton National Park, which the couple had visited.
No details on the cause of death were released. An autopsy was set for Tuesday.
Laundrie has been named a person of interest in the case, but his whereabouts in recent days were unknown.
