From the August 28, 1900 New York Times:

Chicago–Samuel Haynes, sixty-five years old, an inmate of the Hospital for the Insane at Kankakee, walked into the river yesterday and was drowned. Haynes was well known as ‘Senyah,’ the trapee performer. He introduced the flying trapeze act, first presenting it at the old Crosby Opera House. Being injured by a fall, he became a printer, later attempting other ventures, all of which failed. About two years ago he showed symptoms of insanity and was removed to the asylum at Kankakee.”
