The girl is discovered sitting upright, clutching a guitar with her throat slit. Crews and Reese are able to figure out the girl used to play her guitar outside a grocery store nearby. After interviewing one of the grocery store employees along with his son, they become highly suspicious of their behavior.

Meanwhile, Crews decides to take action towards the murder investigation mounting against him.
