NORTH PORT, Fla. — The human remains found in a Florida wilderness park this week have been identified as Brian Laundrie, according to the FBI, ending the weeks long search for the missing fiance of murder victim Gabby Petito.
The bureau said in a statement the remains were identified using dental records. Authorities had turned to experts in analyzing skeletons and bones because the human remains found in the park were bones and not flesh, North Port Police Department spokesman Josh Taylor told the Sarasota Herald Tribune, part of the USA TODAY Network.
Earlier Thursday, the Laundrie family lawyer said the family was "heartbroken" after the discovery human remains and items that apparently belonged to him in the park,.
"It's quite sad, you can imagine as a parent, finding your son's belonging alongside the remains," lawyer Steven Bertolino told CNN. "That's got to be heartbreaking. And I can tell you that they are heartbroken."
Late Wednesday, the FBI announced the discovery in a park with trails that connect to the sprawling Carlton Reserve. Laundrie has been named a person of interest in Petito's death.
Law enforcement officials had searched the area for weeks, but FBI Tampa special agent Michael McPherson said the backpack, notebook and remains were found in an area that had been underwater. McPherson had said investigators would be on the scene for several days.
"I know you have a lot of questions, but we don’t have all the answers yet,” McPherson said Wednesday. “We are working diligently to get those answers for you.”
Just a day after reopening Myakkahatchee Creek Environmental Park, investigators again closed the park to the public Thursday. Marked and unmarked police vehicles rolled into the park.
Lee County Sheriff Carmine Marceno lauded local authorities and the FBI, who he said had been searching in sometimes chest-high water infested with snakes and alligators.
"These are very, very difficult conditions," Marceno said Thursday. "You're searching in areas that you just can't walk up and look. It's not like you're searching a house or a car. These areas are huge, and they're covered by water."
Laundrie disappeared days before Petito's body was found
Laundrie left his home on Sept. 13 for a hike in the Carlton Reserve, nearly 25,000 acres of land in southern Sarasota County, and never returned, his family says. Laundrie's car was found days later at the Myakkahatchee park. For five weeks, law enforcement had combed through the area but found nothing.
Laundrie's parents told the FBI and the North Port Police Department on Tuesday night that they intended to search the park Wednesday morning, Bertolino said. Law enforcement met them there.
Laundrie's father found his son's bag
The parents walked the trail with law enforcement personnel nearby when Chris Laundrie ventured off the trail "zigzagging in different areas" and found a white bag in some brambles, Bertolino told CNN. Chris Laundrie then found law enforcement officers – who had discovered found a backpack and remains, Bertolino said.
Bertolino dismissed as "hogwash" a suggestion that Chris Laundrie had planted the dry bag. He said the parents simply decided to walk the park Wednesday because it was the first day it was reopened to the public.
"The parents had assumed that the experts, the FBI and all the tracking teams they had would be able to locate Brian based upon the information that we had provided them to the specific areas and trails in the park that Brian liked to visit," Bertolino told CNN. "The park had been closed to the public. There was really no other reason for the Laundries to go search anywhere else."
Dental records used to ID remains as Brian Laundrie
FBI officials noted that the area where Laundrie’s belongings were discovered had previously been underwater.
Laundrie likely faced a significant amount of rainfall when his parents said he entered the park, WeatherTiger chief meteorologist Ryan Truchelut said. September and October are the transition months between the summer wet season and the fall dry season in the Sarasota area of Florida
If Laundrie entered the preserve on Sept. 13, his first week in the wild was met with "around 3 inches of rain," according to Truchelut. That week also was cloudy and less hot than normal, with highs in the mid to upper 80s, Truchelut added.
He also added that temperatures have been above normal due to limited cloud cover. Most days have seen highs in the lower 90s since Sept. 20.
By the time law enforcement and Laundrie's family found his belongings and body, all that was left was mostly bones and skeletal remains, according to North Port Police Department spokesman Josh Taylor.
Experts who specialize in analyzing skeletons and bones were brought in to help law enforcement with identifying the remains and the FBI said dental records ultimately showed they belonged to Laundrie.
