Renowned forensic pathologist analyzes Wyoming officials' declaration cause of death is strangulation, on 'The Story'.

A former prosecutor said Tuesday that the Grand Teton County coroner's ruling that Gabby Petito's homicide was caused by strangulation will likely result in a first-degree murder charge for whoever is arrested in the 22-year-old's death. .

Aside from the manner and cause of death, the Teton County coroner could not release much more information about the autopsy due to Wyoming state law. .

Gabby Petito and Brian Laundrie were involved in a domestic incident in Moab, Utah on Aug.

Criminal defense attorney Stuart Kaplan said Tuesday that law enforcement likely gleaned much more information from the autopsy than it has made public and is likely able to either exclude Brian Laundrie, who has been named a person of interest in the case, or connect him to his former fiancée’s death. .
