"It was just a matter of making sure we had everything right," said the coroner.

Gabby Petito's official cause of death was strangulation and the manner of death was homicide, announced Teton County Coroner Dr. Brent Blue at a news conference.

In preliminary findings, her death had been ruled a homicide. It took a month to reach a final autopsy because officials were "exacting" in their examinations, waiting on other specialists to arrive, and finalizing toxicology results.

"It was just a matter of making sure we had everything right," Blue said at the news conference.
