Police spokesman Steve Young says a worker at a Conoco station on the city's north side called police after finding the cardboard box late Wednesday. The box was labeled, "Keep refrigerated."

Young says police aren't sure if the eyes are human, or whether any crime has been committed. Surveillance video shows two men in a blue Toyota leaving the package on the trash bin.
