Valero released a statement Friday regarding the death of a worker at the Valero West plant Wednesday.
The Nueces County Medical Examiner's Office reported that 52-year-old Ezequiel Guzman-Orozco, a contract worker at the plant, fell to his death. However, Valero said early findings from their own investigation show that the worker did not fall but actually suffered a heart attack.
Federal investigators are still looking into it.
