Jimmy was aware of Ruiz's concerns; he had just come into power and was now under pressure from the upper ranks to resolve the situation quickly. Clearly, this so-called upper level included more than just high-ranking government officials, possibly even the mayor and council members.
Jimmy was in a bind, much like before. Although there are two individuals now, the evidence is inconclusive and they need to wait for verification from the forensic department and the lab.
Jimmy's guess was correct. The gun recovered from the amusement park shooting scene, after ballistic comparison, did not match the gun from the first park shooting incident, meaning the park shooting case couldn't be closed yet and they still needed to find the second shooter from that case.
