James Henry Throssell 1866 naturalised US citizen, baker of Newark NJ unknown death

1896 Tuesday 1st Sep The Chicago Chronicle P1 refers. James Henry sustained serious injuries whilst a patient at Dunnings Mental Institute in 1896. There was a report the following year in the Chicago Times-Herald 1897 Jan 9 about body snatching from Dunnings. I can find no record of his death or burial/disposal. He had a wife who was alive at the time and should have been informed. Are there any records of Dunnings that might shed a light on his death or discharge or any history up to his death thereafter. Thank you for your time. Regards JT
