Gabby Petito Update: Laundrie's Initial Autopsy 'Inconclusive' On Fugitive's Cause Of Death

The remains of Brian Laundrie were sent to an anthropologist "for further evaluation" before it will be cremated, according to the family's attorney, after autopsy results came back inconclusive.

"No manner or cause of death was determined," the lawyer, Steven Bertolino, said in a statement. He added authorities stopped short of informing the family when the anthropologist would conclude the evaluation of Laundrie's remains.o

Wednesday last week, Brian's partial remains, which are described to be skeletal by the North Port Police Department, were found in Myakkahatchee Creek Environmental Park, an area connected to the Carlton Reserve after his parents joined authorities in their search for their fugitive son, NBC News reported.

The same day, police would report locating Brian's backpack and notebook near his partial remains as confirmed by dental records.

It came more than a month since the police began their manhunt for the fugitive, who was the FBI's prime person of interest in the disappearance and death of his fiancée, Gabby Petito, 22.

Petito and Laundrie, 23, were chronicling their cross-country trip in the West when the man returned to his parents' North Port home alone on Sept. 1, 10 days before the victim's family reported her missing.

Meanwhile, Laundrie had been missing since Sept. 14 when his parents reported he went hiking in the 25,000-acre Carlton Reserve, which was closed for extensive searches and reopened only last week.

Before he vanished, he had declined to help police in their investigations as they searched for Petito. Police then issued an arrest warrant after Laundrie allegedly used Petito's debit card to make unauthorized withdrawals of more than $1,000 between Aug. 30 and Sept. 1, CBS News noted.

Meanwhile, his family's lawyer would repeatedly clarify that his client was a person of interest in her homicide case but was not charged with Petito's death.

Then on Sept. 19, authorities found her body at the Spread Creek Dispersed Camping Area in Bridger-Teton National Forest in Wyoming. At that time, Laundrie had already gone missing.

The coroner would later note the woman had been dead for at least three weeks when her corpse was found, ruling her death was a homicide by "manual strangulation," according to USA Today.
