Suspected human remains, items belonging to Brian Laundrie found in Florida park, FBI says

What appears to be human remains and items belonging to Brian Laundrie, including a backpack, have been found in a nature reserve in North Port, Florida, according to FBI Special Agent in Charge Michael McPherson.

The remains were found in an area that has been underwater until recently, he said.

The FBI Tampa's Evidence Response Team is on the scene using "all available forensic resources" to process the area. According to McPherson, it's likely the team will be on the scene for several days.

"I know you have a lot of questions, but we don't have all the answers yet," he said reading a statement for the media.

The discovery comes 37 days after Laundrie, the fiancé of Gabby Petito, was reportedly last seen by his parents.
