How the search for Brian Laundrie unfolded

Nina Angelo opened up to “Good Morning America” on Thursday about purportedly seeing Gabby Petito and Brian Laundrie at the Merry Piglets restaurant in Jackson Hole, Wyoming, on Aug. 27, three days after her last known sighting.

The Blue Collar Restaurant Group told ABC News it believes Petito and Laundrie were at its Merry Piglet restaurant and have notified the FBI. However, its security cameras don’t go that far back so there is no footage of the duo allegedly inside the eatery. 

Angelo described Laundrie in vivid detail as "aggressive" and "angry". 

She said the couple was in an angry confrontation with restaurant staff.

“He was just very visibly angry. [Petito] was really upset, she was crying and he immediately went to the hostess stand and was just going in on the hostess and waitress, then eventually the manager,” Angelo said. 

“I think she was being apologetic towards the restaurant staff for his behavior. She just kind of wanted to diffuse the situation. She was like, ‘I’m sorry, come on, let's just go.’ But she was visibly upset. She was crying,” Angelo said. “You could feel his temper. He was he was angry."

Authorities previously said the last time Petito was seen was Aug. 24. 

Aug. 27, the day of the alleged restaurant sighting, was the same day Petito’s mom said she received a strange text from her daughter in which she referred to her grandfather as “Stan.” Petito’s mother said her daughter “never” referred to him as Stan.

North Port, Florida, police announced Wednesday evening that they ended that day's search for Brian Laundrie with no updates on his whereabouts.

The department said it will resume its search Thursday morning.

The Okaloosa County, Florida, Sheriff’s Office said Wednesday afternoon that a man whose image was captured on a wildlife camera in the Florida Panhandle this week is not Brian Laundrie.

The sheriff's office said deputies tracked down the individual, who is a local resident.

The owner of the wildlife camera told ABC News that the image was taken on a wooded trail in Baxter on Sept. 20 and that he alerted the sheriff's office because the man, who was walking with a backpack, resembled Laundrie. Baxter is about 500 miles northwest of where authorities have focused their search for Laundrie in the Carlton Reserve near North Port.

Several Okaloosa County sheriff's deputies who viewed the image recognized the individual from his neck tattoo, enabling authorities to locate and speak to him, the sheriff's office said.

The report of the trail camera image set off an extensive search of the area in Baxter on Tuesday, the sheriff's office said.

The Sarasota County Sheriff's Office confirmed on Twitter Wednesday that its Underwater Recovery Force team has been dispatched to the Carlton Reserve near North Port, where the search for Laundrie is focused.

The sheriff's office, one of multiple law enforcement agencies involved in the search, did not elaborate on why the team was needed at the search site.

"We continue to respond to requests for mutual aid from neighboring law enforcement agencies & federal partners. To confirm, yes, members of our Sheriff’s Underwater Recovery Force have responded to Carlton Reserve," reads the agency's tweet.
