Steven Bertolino is the attorney retained by the Laundrie family after Brian returned to their North Port, Fla., home on Sept. 1 without his fiancée, Gabby Petito. "The probability is strong," Bertolino said to CNN, "that it is Brian's remains." Bertolino's comments followed Wednesday's development that human remains, along with a backpack and notebook belonging to the 23-year-old fugitive, were discovered in Myakkahatchee Creek Environmental Park. The area in which the FBI found the remains had previously been underwater, authorities said.

Prior to the discovery of the remains, the Sarasota County medical examiner's office and a cadaver dog were sent to the park after several items belonging to him were found there on Wednesday.

A warrant for his arrest was issued in late September, accusing Laundrie of unauthorized use of a debit card. His family's attorney has said his parents have no idea where he is. Petito — a Long Island, N.Y., native — and Laundrie had embarked on a cross-country journey in July, traveling from Florida to New York in her white Ford van, then heading west. Petito documented their adventures on her YouTube channel and planned to start a blog about their new, so-called "vandwelling" lifestyle.
