The Milwaukee County medical examiner's office confirmed the death Monday, according to the Milwaukee Journal-Sentinel .

The man, who was not named, complained of chest pain and fell from the ladder last Wednesday, suffering traumatic injuries.

He was transported to a hospital, where he died Saturday afternoon.

An autopsy was performed Monday.
