Apparent human "skeletal remains" were recovered Wednesday in a Florida wildlife preserve where the search for Brian Laundrie has centered, police told ABC News on Thursday.

“We have confirmed skeletal remains," said Josh Taylor, spokesman for the North Port, Florida, Police Department.

Asked of media reports describing portions of the remains recovered, Taylor said, "We have not said anything about a skull.”

Dr. Russell Vega, the chief medical examiner for Florida’s 12th District, confirmed to ABC News that he is working on trying to identify the apparent human remains found Wednesday in a nature preserve along with Brian Laundrie's backpack and notebook.

Vega said it could take several days to identify the remains. He declined to confirm media reports that the remains discovered at the Myakkahatchee Creek Environmental Park in North Port, Florida, were bones.

Early in the search for Laundrie, FBI agents collected samples of Laundrie's DNA from his parents home in North Port, according to the Laundrie family attorney.

Steven Bertolino, the family attorney for the Laundrie family, spoke with New York ABC station WABC Wednesday evening after law enforcement found human remains and items belonging to the fugitive at a Florida park.

The attorney said the area where investigators found Brian's belongings was shown to police two weeks ago when Laundrie's father, Chris, aided in the search.

"I can't say for certain that Chris showed this particular area to police at that point in time, but I can say that this is an area that we initially notified the FBI that Brian liked hiking," Bertolino said.

The attorney said the family is waiting for a proper identification before making any comments.

"As you can imagine, the parents are very distraught. ... At this moment in time they're grieving," he said.

Police have recovered apparent human remains that have not been identified in the search for Brian Laundrie, the FBI said Wednesday.

Authorities also found items belonging to Laundrie, like a backpack and notebook, officials said.

FBI Special Agent in Charge Michael McPherson said the area where the items were found had previously been underwater. McPherson said a team would be on site for several days processing the scene.

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.
