Brian Laundrie, fiancé of Gabby Petito, whose disappearance caused a firestorm late last Summer, died of a gunshot wound to the head, according to an autopsy report released on Monday, Feb. 14.

The body of the young man, who was allegedly responsible for the murder of his then-girlfriend Petito, were found in a heavily wooded area in Sarasota County's Carlton Reservation in October, according to the medical examiner's report, and had been under "up to three feet and possibly more" of water for an extended period of time before being located.

Laundrie's family was informed that his body was found with a gunshot wound to the head, so his death was ruled a suicide, the family's attorney said in November.

Officials said that at the time the body was found, only Laundrie's skeletal remains were found due to "extensive carnivore activity," such as scavenging by coyotes, rodents and raccoons.

The 47-page forensic report also detailed items recovered at the site where Laundrie's remains were found, including a backpack with a tent and flares, a red paper and hat with a "Moab Coffee Roasters” logo, and a wooden box containing a small notebook and photos.

The FBI said the 23-year-old confessed in writing before committing suicide that he had killed his girlfriend in September 2021.

"A review of the notebook revealed written statements by Mr. Laundrie in which he took responsibility for Petito's death," the FBI said in a statement.
