(NEW YORK) -- A massive search for Brian Laundrie, the boyfriend of slain 22-year-old travel blogger Gabby Petito, took a dramatic twist Thursday with the announcement that human remains found in a Florida nature preserve are those of the wanted fugitive, according to the FBI.
The remains were recovered Wednesday, nearly five weeks after Petito's body was recovered in the Bridger-Teton National Forest in Wyoming. The Teton County Coroner ruled her death a homicide by strangulation.
The search for the 23-year-old Laundrie was centered around North Port, Florida, where investigators said he returned to his home on Sept. 1 without Petito but driving her 2012 Ford Transit.
Laundrie had been named by police as a "person of interest" in Petito's disappearance and a federal warrant had been issued for him alleging unauthorized use of Petito's credit card.
He refused to speak to the police and vanished on Sept. 13. His parents told investigators they believed he was headed to the Carlton Reserve in North Port.
The case grabbed national attention as Laundrie and Petito had been traveling across the country since June, documenting the trip on social media. Petito's parents reported her missing on Sept. 11 after not hearing from her for two weeks.
Here is how the weekslong search for Laundrie unfolded:

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.

Laundrie family attorney reacts to discovery of apparent human remains
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.
