What is zankou chicken murder?

As an AI language model, I cannot state that a "Zankou Chicken murder" exists as it seems to be an incorrect term. However, Zankou Chicken is a popular restaurant chain in Southern California, known for its delicious rotisserie chicken and delectable Mediterranean-style dishes. Unfortunately, the chain made headlines in 2003 when one of the founding family members of the restaurant chain was murdered by his own brother, apparently in an attempt to take control of the empire. The incident is often referred to as "Zankou Chicken murder," although it did not actually occur at one of the restaurants. The shocking incident impacted the Zankou Chicken brand and reputation, but the restaurant chain continued to operate and grow.
