When the Night Comes Falling

Also known as a “tummy tuck,” an abdominoplasty is a popular plastic surgery procedure that removes fat and skin from the belly and abdomen, usually for cosmetic reasons. After losing a hundred pounds in his late teens, Bryan Kohberger undergoes the costly surgery to tighten the loose skin around his abdomen, as a way of acquiring the “rock-hard torso” of his dreams.

The Behavioral Science Unit (BSU), currently known as the Behavioral Analysis Unit, is a division of the FBI that specializes in the analysis of violent crime through an evidence-based understanding of the criminal mind. Shaken by the brutality of the four murders, Moscow Police Chief James Fry recalls a lecture by a member of the BSU about the psychology of killers; this inspires him to ask for the FBI’s assistance in the case.

BOLO, cop parlance for “Be On the Lookout,” is a bulletin issued to police and (sometimes) the general public, asking them to keep an eye out for a specific criminal or a clue that may help in an investigation. After the Moscow suspect’s car is identified by video analysis as a Hyundai Elantra, the Moscow PD issues a nationwide BOLO to both law enforcement and the public, describing the car but saying only that police believe the occupant may have “critical information” about the case.
