I didn't find anything in a local newspaper, but the Eau Claire Leader, Wisconsin newspaper wrote an article about the event, saying: "A motorman who attempted to take a car out of the barn was assaulted so badly that in all probability he will die."
Well, Horace did not die for another 45 years, all of which he spent in the Protestant Hospital for the Insane in Verdun, Quebec. My grandmother worked so my mother was looked after during the day by my great grandmother, Mary Jane Porter King. Mary Jane was Horace's oldest sister, and she would take my mother with her once a week to the hospital to visit Horace. My mother remembers being made to sit outside on a bench to wait, as she was too young to go in the hospital. Horace died in 1948, and was laid to rest beside his parents in Ulverton.
Horace was on both the 1911 and 1921 Censuses as an inmate at the Verdun Hospital. If you are missing an ancestor, did you look in the census or registers of the local Insane Asylum?
My step-son's great-grandfather, Dr. William Herbert Wiley was the owner of Blythewood, in Greenwich, CT.
