On Criminal Minds Season 12 Episode 11, Beth Simms' murder doesn't fit the pattern the BAU was expecting.
They've been tasked with looking into a bizarre case involving a clue uncovered on a series of bodies when an anatomy class teacher noticed something strange - a tiny ink drawing.
But this wasn't any teacher in the class. Also the county coroner, another ten-year-old case instantly came to mind and when the facts didn't add up, she knew she needed help.
Walker points out how the drawings change, almost seeming to grow as the bodies multiply.
What does it mean? Is it a message? If it's a killer's signature, changing it seems unlikely.
More importantly, why doesn't Beth have it?
Beth, who weathered tough times in the past, had cleaned up her act, but that didn't mean she fit into the group of seemingly Citizens of the Year who were also killed by this mysterious unsub.
Prentiss, Walker and Rossi, though, make relatively quick work of narrowing down the information, and with a call to Garcia, the pieces start to fit together.
It's off to Florida for our trusty team, and we have little doubt they'll go even further to solve the crime.
