Search for Brian Laundrie resumes after FBI confirms Wyoming body is Gabby Petito

The FBI confirmed Tuesday that the remains found over the weekend in Grand Teton National Park were those of Gabrielle "Gabby" Petito, the Florida woman who vanished during a cross-country trip with her fiancé.

According to the agency's Denver field office, the Teton County coroner confirmed the identity and said the manner of death was homicide, but a specific cause of death will have to wait for the full autopsy results.

The only person of interest in Gabby Petito’s case has yet to be found. On Tuesday morning, police announced they were resuming their search in the Carlton Reserve, the 25,000-acre park in Sarasota County, Florida, where crews were over the weekend. 

One of the final messages that Gabby Petito’s family is believed to have received from her was in the form of an "odd text" sent at the end of August, when loved ones began to grow concerned about her wellbeing, according to the state search warrant released Monday.

Gabrielle Petito, 22, sent her mother, Nichole Schmidt, a text message on August 27, in which she wrote: "Can you help Stan, I just keep getting his voicemails and missed calls," states the search warrant, filed in the Sarasota County Circuit Court on Friday and made public Monday.

According to the document: "The reference to ‘Stan’ was regarding her grandfather, but per the mother, she never calls him ‘Stan.’ The mother was concerned that something was wrong with her daughter."
