After weeks of speculation, the cause of death for Gabby Petito has been released. When Petito’s autopsy was performed, the coroner said quickly that Gabby was murdered. This week, we found out that the young woman was strangled to death by “human force.” Dr. Brent Blue said that Petito was throttled. In today’s Body Bags, death investigator Joseph Scott Morgan explain what throttling means, and what clues the coroner may have found to lead to that ruling.
