Brian Laundrie's Family Won't Hold A Funeral, As Autopsy Results Come Back As Inconclusive, Attorney Says

Brian Laundrie’s remains have been sent to an anthropologist after the results of an autopsy were inconclusive.

“No manner or cause of death was determined,” the family’s attorney Steven Bertolino told NBC News.

Bertolino added to People that the family plans to cremate the remains and “there will be no funeral service” to remember him.

Laundrie’s remains were discovered Wednesday at the Myakkahatchee Creek Environmental Park after a more than month-long search for the 23-year-old, who disappeared just as efforts to locate his missing girlfriend, Gabby Petito, were ramping up.

Bertolino told Oxygen.com last week that Laundrie had been “very distressed and upset” when he left his parents’ home on Sept. 13 and headed to the 25,000-acre Carlton Reserve, which connects to the environmental park where his body was later discovered.

Investigators found the remains in an area of the park that had previously been submerged in water. The FBI has said they were able to positively identify the remains—which were found alongside Laundrie’s backpack and a notebook—using dental records.

An anthropologist is now expected to examine the remains for “further evaluation,” Bertolino said.

Laundrie’s family has faced criticism for staying silent as investigators searched first for Petito, whose body was discovered in Wyoming on Sept. 19, and then for Laundrie, but Bertolino has insisted that the family stayed mum because of his advice.

He also shot down rumors that Chris and Roberta Laundrie had helped their son disappear or had reached a deal with prosecutors before agreeing to aid in the search to find their missing son, NBC News reports.

Petito and Laundrie embarked on a cross-country trek in July to visit the nation’s national parks as they traveled in a van they had converted into a camper.

Petito shared picturesque images of the pair on social media and in a YouTube video frolicking on the beach, kissing and hiking together as they toured the country, but the ill-fated trip soon took a dark turn.

Moab Police stopped the pair in Utah on August 12 after getting a report about a possible domestic dispute.

A witness called 911 to report seeing a “gentleman slapping the girl,” according to audio obtained by Fox News, but when police pulled the couple over outside Arches National Park, Petito told police that she had been the one to slap Laundrie first.

After talking separately with Petito and Laundrie, they determined that Petito had been the “primary aggressor.” They noted, however, that they believed it had been more of a “mental/emotional health ‘break’” and chose to separate the couple for night rather than make any arrests, according to a police report obtained by Oxygen.com.

Just weeks later, Petito disappeared.

Her body was later discovered in the Grand Teton National Park in Wyoming. A medical examiner determined the 22-year-old had been strangled to death.

Police have said Laundrie returned to Florida, without Petito, in the couple’s van on Sept. 1.

Her mother reported her missing on Sept. 11 after she had been unable to reach her daughter for days, launching the highly publicized investigation into her disappearance.
