Human remains and the body of a dog were found in Florida, in the Tampa area, not far from where objects belonging to Brian Laundrie, the boyfriend of Gabby Petito, the girl found strangled in Wyoming, were found.
The FBI has made it known.
Exams are underway to verify the identity of the body.
Among the objects found off a trail in the Myakkahatchee Creek Environmental Park and, apparently, belonging to Brian Laundrie, are a backpack and a notebook, the investigators explained.
A medical examiner is on site to investigate the case.
