The Milwaukee County Medical Examiner’s Office reports the 60-year-old worker injured at the Caterpillar weld shop last week has died of his injuries. Steve Wade of Oak Creek suffered what the office called “traumatic crushing injuries” last Thursday when a heavy metal plate fell on him while he was on the job. Wade’s death was announced Monday. The Occupational Safety and Health Administration has a team of investigators on the scene to determine if more action is necessary. The Milwaukee County District Attorney’s Office and South Milwaukee Police Department are handling the case locally.
