Input: Captain Victoria Gates:  You 're telling me Eric Chambers is not our shooter ? Based on what ?
Kevin Ryan: Physics , sir .
Kate Beckett: Congressman Lopez said that when he talked to Carolyn Decker , he saw Chambers by the far wall .
Kevin Ryan: Which is where CSU found his prints .
Richard Castle: And seconds later , our assassin opens fire , three shots .
Kevin Ryan: The first _ one _ strikes Lopez beneath the left clavicle .
Kate Beckett: The second one grazes Carolyn Decker 's shoulder , and then the third one strikes her in the upper back .
Kevin Ryan: That shot severs her pulmonary artery ; she never has a chance .
Captain Victoria Gates: How does any of this lead you to think that Chambers is not the assassin ?
Richard Castle: Chambers ' vantage point . He had a side - angle view of Lopez and Carolyn Decker .
Kevin Ryan: So how did Chambers manage to shoot Carolyn in the back ? The answer is that he could n't have . Not unless that bullet magically took a hard right turn in midair .
Richard Castle: Which means the shots were fired from the grassy knoll , metaphorically speaking .
Captain Victoria Gates: Detective Beckett , do you actually find any of this plausible ?
Kate Beckett: Yes , sir . Plausible enough that I 'm getting Ballistics to re - evaluate the crime scene .
