Disturbing new details have emerged in the death of Brian Laundrie, including evidence his body had been gnawed by animals.

Grisly new details emerged in the death of Brian Laundrie, including that the majority of his bones were discovered scattered in “plain sight” and had been gnawed on by animals after his death.

Laundrie, 23, died from a self-inflicted gunshot wound to the head that caused extensive fractures in his skull, according to a newly released report by a Florida medical examiner’s office, the New York Post reports.

The single bullet entered his head at the left temple and exited through the right, travelling slightly upward, said the full autopsy and forensic report.

Authorities recovered “the vast majority of the skeleton,” aside from a few bones from his teeth and his face, they said.

But his bones did show signs of “gnawing and chewing” from “post-mortem scavenging/carnivore activity” — including portions from his arms and legs, the report said.

Laundrie’s toxicology report showed no sign of drug use.

Other new information about the scene where Laundrie’s remains were discovered included that authorities found his skeleton and personal items — including a pair of green shorts, slip on shoes, a white metal ring, a backpack and a handgun — on the dirt ground. The scene was secluded by “overgrown vegetation,” the document said.

At the nearby “secondary” scene, authorities found animal skeletal remains that could be evidence of hunting, a handwritten half note and a “MOAB Coffee Roasters” hat, according to the report. Authorities also located a drybag with Laundrie’s journal and a wooden box with a small notebook and a picture of himself.

Laundrie was sought in Gabby Petito’s disappearance and death when his remains were discovered at the 10-hectare Carlton Reserve near his parents’ home in North Port, Florida, on October 20.

Police said his remains had been laying around for weeks inside the marshy park before they were found, initially creating some challenges for coroners.

The young couple was on a cross-country trip when Petito, a 22-year-old Long Island native, went missing and Laundrie returned home in her van without her September 1.

Her remains were found in a Wyoming campground on September 19.
