NCIS crime of the day is a triple homicide discovered by a stripper.
Killer set up Officer Shelley, framed the crimes as if he was retaliating- having a serious grudge against Shelley's bullies in high school. Not surprisingly, we are led to believe it is the stripper's boss, Hector. Elena as the revealed killer, who also set up Shelley, is somewhat of a stretch. Not nearly as interesting as the subplots of the team members- especially the big reveal discussed below.
