UPDATED 10/21, 5:42 p.m. ET: The human remains that were discovered earlier this week are those of Brian Laundrie, the FBI said in a statement on Thursday.

Steven Bertolino, the attorney representing the family of Brian Laundrie, agrees that the human remains found earlier this week are likely to be those of the 23-year-old person of interest in the Gabby Petito case.

“It’s quite sad, you can imagine, as a parent,” Bertolino told CNN’s Chris Cuomo during an interview on Wednesday. Asked about the remains, which have not yet been officially identified, Bertolino pointed to the likelihood that they are indeed Laundrie’s while also noting that he and the family will await formal results.

“It’s not about belief,” he said. “As you said at the onset, the probability is strong that it is Brian’s remains but we’re gonna wait until the forensic results come in and verify that.”

Bertolino, who’s known the Laundrie family for “well over 20 years,” also addressed the speculation surrounding the family’s silence amid the widely publicized case.

“I’m the one who told them not to talk,” he said. “That’s been on me from day one. That’s not on the family. And if it turns out my legal advice is wrong in that perspective, so be it. But that’s on me, not on the family.”
