The robbers, though not seen initially, were attempting to escape a heist they had committed, trying to flee the chasing Linden County police in the process. As they were chased, Rick, Shane, Leon, Lambert, and several other King County policemen set up a roadblock and waited for them. The road-spikes set punctured the robbers tires and flipped the car over, resulting in a wreck. The men from both stations then surrounded the trio and ordered their surrender. The men, one by one, began exiting the vehicle, firing at the officers, almost injuring some. The first two to exit, who were thought by the police to be the only men inside, were immediately shot down, with Rick being shot in the stomach. After the initial shootout, Rick reveals that he was wearing a Kevlar vest, saving his life. As Rick confronts Shane about not telling Lori about his near death experience, the third robber exits the vehicle and shoots Rick in the back, the man is quickly shot dead by Shane. This shot resulted in Rick's trip to the hospital and put him in a coma for an unknown period of time.
