As we reported, the FBI discovered a skull and other remains while walking around the park with Brian’s parents Roberta and Christopher.
The bones were found near other property belonging to Brian including a notebook and a backpack.
The Laundrie family attorney Steven Bertolino confirmed Brian’s parents were notified the autopsy did not determine the cause or manner of death. The Medical Examiner explained he was unable to solve the mystery.
Bertolino said law enforcement will now send the bones to an anthropologist to examine. It appears the remains had decomposed so much that the examiner wasn't able to do anything with them.
Brian has been missing since September 13 after telling his parents he was going for a hike at the park. His parents say they quickly told authorities about him being MIA. The FBI and local police immediately launched a manhunt for Gabby Petito's fiancé.
Prior to him leaving, Brian refused to speak to police about Gabby's disappearance and hired a lawyer. A couple of days later, her remains were found inside Wyoming's Grand Teton National Park.
An attorney for Gabby Petito's family said the slain 22-year-old's parents would not be commenting on Brian being found. "Gabby’s family is not doing interviews or making a statement at this time. They are grieving the loss of their beautiful daughter. Gabby’s family will make a statement at the appropriate time and when they are emotionally ready," he said.
