A Wyoming coroner on Tuesday said Gabby Petito, the 22-year-old travel blogger whose remains were recovered in September in a national park, died by strangulation.
Petito's boyfriend and cross-country traveling companion, Brian Laundrie, has been named by investigators as a person of interest in her death and is the subject of a massive nationwide search being directed by the FBI.
Teton County Coroner Dr. Brent Blue told reporters Petito's manner of death was homicide. The cause is officially listed as "manual strangulation/throttling."
Blue described conducting a "detailed investigation" with the assistance of the FBI that included a full-body computed tomography scan and examinations by a forensic pathologist and a forensic anthropologist.
"We hereby find the cause of death by strangulation and manner is homicide," Blue said.
Petito's body was discovered on Sept. 19 in the Bridger-Teton National Forest near Jackson.
Blue said the autopsy determined that Petito's body had been exposed to the wilderness for three to four weeks. He did not release an exact day investigators believe Petito was killed.
Blue said that Wyoming statutes limit the amount of information he is allowed to make public about the autopsy.
He did say Petito was not pregnant at the time of her death.
Blue declined to answer when asked if he suspects Laundrie is responsible for Petito's homicide, saying that will be up to law enforcement to determine.
"Nothing is obvious in a situation like this, so detailed analysis was used both to determine manner and cause of death," Blue added.
Blue's announcement comes amidst a nationwide search the FBI is leading for Laundrie, who drew suspicion after returning to his parents' North Port, Florida, home on Sept. 1 without Petito but driving her van, authorities said.
Laundrie's parents told police they last saw their son on Sept. 13, two days after Petito's parents, who live in Long Island, New York, reported her missing. Laundrie's parents told investigators their son may have been headed to the Carlton Reserve, a 25,000-acre wildlife preserve near their home.
Blue said the case has been "quite the media circus, and continues to be."
"Unfortunately, this is only one of many deaths around the country of people who are involved in domestic violence, and it's unfortunate that these other deaths did not get as much coverage as this one," Blue said. "I'm assuming, because the deceased was a blogger, that this received more coverage than others but there are a lot of both men and women who have lost their lives that aren't covered with this kind of media attention."
