A worker found unconscious at Lyondell Basell Industries Houston refinery on Thursday died from natural causes, the Harris County medical examiner's office said on Friday.
An autopsy found hypertensive and atherosclerotic cardiovascular disease to be the cause of death of the 56-year-old man, said Tricia Bentley, spokeswoman for the
Harris County Institute of Forensic Sciences.
The worker was unresponsive when found at the refinery on Thursday morning. He was taken to a Houston-area hospital where he was declared dead.
