The unnamed man was working with an industrial-sized machine near a car dealership when the accident happened.

"It's the type of wood chipper where the chute end actually will push the debris into the back of the truck so it can handle large branches," Detective Seth Tyler told KTVK.

"It's extremely powerful."

Police in Chandler, Arizona said the worker simply tripped and fell into the machine. He was decapitated.

Making matters worse, the Arizona Republic says the man's two sons were also on the crew and watched as their father was killed.

Family member Brenda Zapata told azfamily.com, "this situation is very terrible, yes." said family member Brenda Zapata. "We're never going to see his smiling face one more time."  The paper reports after the incident, “a straw hat lay on the ground next to the wood chipper."
