The family of a Dickson native who died last year in the cooler of his restaurant has filed a multi-million dollar lawsuit against several companies and Metro Nashville Police for alleged negligence. The lawsuit filed last week in Nashville names several companies for their role in the June 17, 2012, death of Walter Johnson “Jay” Luther Jr., the co-owner and chef of Germantown Cafe East. Luther’s mother, Norma Luther of Dickson, and sisters, Debbie Ruf of Dickson and Kim Bartels of Nashville, are seeking $10 million from the company that supplied the dry ice and unspecified damages from the cooler company, two security companies and Metro Police. A 1983 graduate of Dickson County High School, the 47-year-old Luther died from carbon dioxide poisoning when he became trapped in the cooler of the restaurant at 5th and Main streets in Nashville. The lawsuit claims Southeast Cooler Corporation of Georgia was negligent in failing to provide proper safeguards, Continental Carbonic Products of Illinois did not warn about the dangers of dry ice, Signature Security Service of Smyrna failed to properly assist police, ADS Security of Pennsylvania failed to convey the urgency of the situation and Metro Police did not property investigate an alarm at the restaurant. Police said Luther apparently went to the restaurant while it was closed due to a planned power outage in the area to check on stock, for which the restaurant had ordered 500 pounds of dry ice to preserve. Police said the cooler door closed behind Luther and the interior release was broken. Luther apparently activated an alarm from inside the cooler but when police met a security guard outside the restaurant it appeared secure and they did not enter the business, attributing the alarm to the power outage. The medical examiner said Luther died from carbon dioxide poisoning in a matter of minutes. His body was found inside the cooler the next morning.
