GREEN BAY, Wis. (AP) — Investigators are probing a fatal construction accident in Green Bay.

The Green Bay Press-Gazette reports a 52-year-old man was killed Friday morning on the city’s northeast side. Police would not identify the property where the incident occurred, saying only the death involved a vehicle accident.

The federal Occupational Safety and Health Administration confirmed it is investigating Jamar Co., a subcontractor working on a new mill project at Green Bay Packaging in the same block where the man was killed.

Miron Construction and Green Bay Packaging both issued statements saying the man worked for one of the subcontractors working on the site.

The $500 million mill project has required the work of about 600 subcontractors. Work at the site began in 2018.
