The prior warrant to search the motel room for Rosa had to be limited in time and scope. It did not extend carte blanch authority to the police power. It was proper, therefore, and good police work, to seek a second warrant with the specificity to search for poison and secure potential evidence that would not be excludable at trial.
Henri Lubatti (who played Costa Vayas), Brad William Henke (who played Sal Vayas), and Monique Gabriela Curnen (who played Amaya Vayas) all had small roles in various episodes of CSI: Miami.
