Witness Says She Saw Gabby Petito In 'Blowout' In Wyo Restaurant

BLUE POINT, NY—Another eyewitness claims to have seen Gabby Petito before her disappearance in late August. Nina Celie Angelo, of New Orleans, recounted seeing what she called a "blowout" with Brian Laundrie arguing with restaurant staff at The Merry Piglet in Jackson Hole on August 27 while she was vacationing with her husband.

Investigators and the media have been tracking Petito's last days in Utah and Wyoming through social media reports, video footage and police reports. But if Angelo's account is true, this would be the last sighting of Petito alive.

Angelo told the story on Instagram this week, explaining that she and her husband didn't realize a couple they saw in an altercation at the restaurant were Petito and Laundrie until they viewed the body cam police footage of the couple that has been playing on news stations all week.

"It's something you don't see every day. The way he's acting, she's crying...you could tell he was angry," she said of what she witnessed during lunch in Jackson Hole that day.

Angelo told ABC News that Laundrie left and reentered the restaurant several times while Petito cried on the sidewalk. Petito at one point apologized to the staff for Laundrie's behavior, she added.

Laundrie, Petito's boyfriend who she was on a multi-month road trip with, is a person of interest in her death and is currently missing. A Florida manhunt in a nature preserve continues to search for signs of the 23-year-old, who is also a Long Island native.

"He was just being very aggressive. It's almost like he was screaming. He would not let it go," Angelo remembered, explaining she didn't know why he was mad at the wait staff.

The Mexican restaurant, The Merry Piglets, posted the following announcing on Instagram on Wednesday:

"Yes, we can confirm Gabby and Brian were in Merry Piglets. We have already notified the FBI and they are aware."

The news of the 22-year-old Blue Point native's death, which has been ruled a homicide by the FBI, has shaken Long Islanders as well as people from across the country and world.
