Officials continue to investigate the death of an electrician who fell from a ladder at the construction site for the new Milwaukee Bucks’ arena. The county medical examiner’s office says a 57-year-old Menomonee Falls man complained of chest pains and fell from an eight foot ladder last Wednesday. Officials say he died Saturday at a hospital after suffering some traumatic injuries. An autopsy has been completed, but the cause of death has not been determined. The victim’s name was not immediately released.
