On Sunday, human remains consistent with the description of Gabby Petito, the "van life" blogger who disappeared while on a cross-country van trip with her fiancé Brian Laundrie and whose fate has stirred a growing digital frenzy, were found in Wyoming. On Tuesday, a tweet from the FBI Denver field office confirmed the remains found were those of Petito, who was reported missing on September 11, and said "the initial determination for the manner of death is homicide."
Stories like Gabby Petito's capture all women's imaginations because they highlight the fact that women are at most risk from those they should be able to trust. We listen to true crime podcasts, pore over the timelines from news stories, look at the apparently happy, carefree photos of the victims, and wonder whether we'd be able to spot or intercept a threat close to ourselves, a friend, daughter, or sister.
