An employee of an exterminating company who was found unconscious in the company's parking lot died of a heart attack that had no connection to any toxic materials, the Los Angeles County coroner's office said.
Patrick S. Stevenson, 39, a Chino resident and sales manager of Orkin Exterminating Co., was found slumped over the steering wheel of his car Jan. 14, a day after a toxic chemical leak was detected at Orkin Exterminating Co. in Glendale.
He died 90 minutes later at Glendale Memorial Hospital, prompting the attending doctor to speculate that his heart attack may have been induced by an organic phosphate poison.
However, an autopsy report released last week stated that Stevenson's heart failure had no connection to any toxic substance. "What happened was his coronary arteries were just plugged up," coroner's spokesman Gary Gilmour said.
