Greif Brothers (defendant) hired Bator (defendant) as an armed security guard to protect its property. Other than telling Bator to periodically check the parking lot, Greif Brothers did not instruct Bator about the methods to protect its property. One night, Bator became involved in a confrontation with a trespasser, Pusey. Bator shot and killed Pusey, and Pusey’s mother (plaintiff) brought a wrongful death and survival action against Bator and Greif Brothers. Bator settled with Pusey, but the trial court granted a directed verdict in favor of Greif Brothers. The appellate court affirmed the judgment.
