Teton County Medical Examiner Dr Brent Blue said on Tuesday Gabby Petito's cause of death was strangulation and confirmed it to be homicide.
The doctor announced the results at a press conference on Tuesday, nearly a month after Petito, 22, was reported missing following a road trip with her fiance Brian Laundrie, 23.
His body was found in Wyoming's Bridger-Teton National Forest on September 19.
In his preliminary findings, the coroner had already found a homicide, but the cause of death had remained unresolved pending the results of the autopsy, according to the FBI.
Wyoming authorities provided an update on Gabby Petito's final autopsy report during a press conference early Tuesday afternoon in the United States which has allowed the question to be answered so far without answer on the circumstances of his death.
Brian Laundrie still wanted
Gabby Petito's body was found in a remote section of a Wyoming forest. "The FBI and our partners remain committed to ensuring that anyone responsible for or complicit in Ms. Petito's death is held accountable for their actions," Michael Schneider, FBI special agent in Denver, said in a statement. Brian Laundrie her boyfriend, the main suspect in this case was still not found on Tuesday. He is actively wanted by the police.
A call for witnesses has also been issued for anyone who passed the couple on a camping area in Grand Teton National Park between August 27 and 30.
The case fascinated American and foreign Internet users, who followed and commented on all the stages of the vast search operation to find the 22-year-old woman, who went missing on September 11 during a traveling trip with her companion. .
