“Chris and Roberta Laundrie have been informed that the cause of death was a gunshot wound to the head and the manner of death was suicide,” said attorney Steven Bertolino.
CNN has reached out to authorities for further comment, and has followed up with Bertolino regarding how Laundrie came to be in possession of a gun.
The couple had been traveling across the country over the summer in a converted van and documenting their travels on social media. The case gained national attention as authorities searched for both.
Laundrie returned to his parents’ house in Florida on September 1 without Petito. As police were trying to question the family about Petito’s whereabouts, Laundrie went missing on September 13 or 14 after leaving home with a backpack, according to his parents.
Petito’s remains were found in Wyoming on September 19. Her death was ruled a homicide by manual strangulation.
Petito’s family says they are “aware of the circumstances” regarding Laundrie. But they are not making an official comment at the request of the US Attorney’s Office and the Teton County Prosecutor’s Office in Wyoming, according to a statement from the family.
The family was asked not to make any comments while the investigation into her death is ongoing, the statement said.
A Florida medical examiner’s office confirmed Tuesday Laundrie had died of suicide by a gunshot wound to the head.
The office won’t make the autopsy report public “until the law enforcement investigation is complete,” the office said in a release.
What led to Petito’s death remains a mystery. The FBI had described Laundrie as a “person of interest” in her murder, but he was not charged. He had, though, been indicted for allegedly using two accounts that belonged to someone else in the days after she died.
The notebook was wet at the time, and officials haven’t yet said whether they have gained any information from it.
Bertolini said in October Laundrie’s parents had discussed “several times” the possibility their son had died by suicide.
