A 22-year-old "van life" blogger who went missing on a road trip with her fiancé was strangled to death, a Wyoming coroner has ruled.
On Tuesday, Teton County Coroner Brent Blue said Gabby Petito been dead for three to four weeks by the time her body was discovered.
Her body was found last month inside a national park the couple had visited.
Fiancé Brian Laundrie is considered a person of interest in the case. He has been missing since mid-September.
The case of the missing travel influencer has captured national public interest and highlighted other similar missing persons cases.
Dr Blue told reporters in a news conference that Ms Petito's body was found in a wilderness campsite with signs of strangulation.
He would not confirm the specifics, or if an item was used to kill her.
He added that he could not disclose details of her toxicology report, but did say that she was not pregnant at the time of her death.
The ruling on her cause of death follows an initial post-mortem in September.
Ms Petito's body is in the local mortuary, Dr Blue said, and officials are in contact with her family about transferring her remains to them.
"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 do not get as much coverage as this one," Dr Blue added.
In July, Ms Petito set off on a road trip from her hometown in Long Island, New York, with Mr Laundrie.
The pair had been documenting their nomadic "van life" trip through national parks in the American West on social media.
The couple had been travelling for several weeks before Mr Laundrie returned home to Florida alone with their white van on 1 September. He did not contact police or the Petito family on his return.
Ms Petito's family reported her missing on 11 September.
Mr Laundrie, currently the only person of interest in this case, remains missing. His family say he left for a hike on 14 September and never came back.
Police and FBI teams are scouring the Carlton Reserve, a 24,000-acre county park in Florida's Sarasota County with police dogs, drones, and all-terrain vehicles.
The FBI has issued a federal arrest warrant, charging him with fraudulently using a debit card after Ms Petito's death.
He has not been charged with crimes relating to Ms Petito's killing.
