Caroline's mother Michelle meets with Kinsey and asks her to work the case because she cant go home without knowing someone is on the case full time.
Kinsey meats with Caroline's boss David Cole at the dinner she works at to see if anyone was harassing her or threatening her or someone Caroline talked about that she was worried. After this she thinks she finds the car of the murderer but she finds out it was the wrong one.
Kinsey talks to Caroline's roommate Judy about somebody who might of had something do do with it like an old boyfriend and everything that Kinsey asks Judy responds with I dont know.
Kinsey finds the blue truck at the shooting in the roommates house garage and finds the gun used in the front seat of the car and when she is leaving she spots the person she had seen at the shooting supposedly Caroline's brother.
When Kinsey spots the person she saw at the crime scene which was Caroline's roommates brother and chases him and when she chases him he crashes in the exact same spot where he killed Caroline and Kinsey goes back to her office and looks at the picture of Caroline and says what used to be a sad face is not so sad anymore.
