WHITE PIGEON, MI   (WKZO) --   State Police have released the name of the St. Joseph County man who was found dead in a vat at the White Pigeon Paper Mill just before noon on Sunday. 

They are hoping that autopsy results will tell them whether 61-year-old Robert Knight, who had a history of heart problems, suffered a medical issue before falling into the vat or whether it was an industrial accident.  Knight was a welder.
