However, based on witnesses and preliminary findings, Mr. Guzman did not fall. Early indications are that he may have had a heart attack."
Guzman's employer Brand Energy & Infrastructure Services also said in a statement that his death was not work related.
"Early investigations at the site indicate that Mr. Guzman's death was not the result of a fall from height or other work-related accident," the company said, KRIS-TV reported.
