A coroner has ruled Gabby Petito died by strangulation. But these questions are left unanswered

There is now a clearer picture of what happened to Gabby Petito after a coroner said Tuesday that she died by strangulation. But many questions remain unanswered including who killed her, when she was killed and what happened leading up to her death.

Teton County Coroner Dr. Brent Blue had previously ruled Petito's death a homicide, and though the cause was revealed Tuesday, he declined to provide details about Petito's autopsy or a potential suspect, saying he was limited in what information he could legally release.

Who killed Petito, when she was killed and what happened leading up to her death remain a mystery.

Even though there are more than 90,000 active missing person cases in the U.S., few have met with as much urgency and national attention as that of Petito, who was reported missing in September 11 and whose remains were found more than a week later in Wyoming's Bridger-Teton National Forest.

Authorities are still searching for her fiancé, Brian Laundrie, who returned to Florida without her after their trip across the Western U.S.
