Abstract: On June 15, 2009, Employee #1, a store owner, was heard gasping for air inside a locked restroom by a passing worker. The worker kicked the restroom door open and found Employee #1 lying on his back, on the floor, and unconscious. The worker then dragged Employee #1 out of the restroom and summoned assistance. A security systems installer who was in a nearby office helped the worker carry Employee #1 to the front of the store. Employee #1 died, and the death was attributed either to a heart attack or cyanide poisoning. The investigation revealed no chemical odor in the restroom, on Employee #1, or in the surrounding area; however, a hazmat team found a few ounces of a cyanide chemical inside a bucket in the restroom.
