911 Caller Said He Saw Brian Laundrie Hitting Gabby Petito: 'Gentleman Was Slapping the Girl'

A man who called 911 to report a dispute between Gabby Petito and Brian Laundrie told the dispatcher he saw a man hitting a female, according to audio of the call obtained by PEOPLE, seemingly undermining the assertion of police that the incident was not a domestic assault.

"We drove by and the gentleman was slapping the girl," the caller tells the dispatcher.

"He was slapping her?" the dispatcher replies.

"Yes, and then we stopped. They ran up and down the sidewalk. He proceeded to hit her, hopped in the car and they drove off," the caller adds.

After the 911 call, the couple was pulled over by police in Moab, Utah, on Aug. 12, and their encounter with officers was captured on body camera footage that has been publicly released. In the footage, Petito, 22, admits to striking Laundrie, 23, while Laundrie admits to pushing his fiancée.

A responding officer wrote in the police report, which was obtained by PEOPLE, "After evaluating the totality of the circumstances, I do not believe the situation escalated to the level of a domestic assault as much that of a mental health crisis."

However, another officer wrote in the report, "It wasn't clear, but I believe it was reported the male had been observed to have assaulted the female."

After the couple spoke with police, Petito went back to the customized van in which the couple was traveling and Laundrie stayed the night in a hotel, the police report states.

The incident was classified as "disorderly conduct."

Petito last made contact with her family on Aug. 24 and was reported missing on Sept. 11. On Sunday, authorities announced they had discovered a body in Grand Teton National Park in Wyoming they believe is Petito's.

Police in North Port, Fla., where the Laundrie family lives and where the couple had lived before they set out on a cross-country trip in their van, have said they believe Petito was in the national park when she last contacted her family.

While the body has not been formally identified, FBI agent Charles Jones said at a Sunday press conference that the bureau "would like to extend sincere and heartfelt condolences to Gabby's family."
