Doheny was then placed under the care of Dr. E. C. Conroy and a nurse, Oberlin Howarth. Doheny's condition did not improve and was worsened after he read about the Pirates' fourth loss in the 1903 World Series. On the night of October 10, he forcibly removed Conroy from his home. Early the next morning, Doheny attacked Howarth with a cast-iron stove leg and knocked him unconscious. The police arrived, and Doheny held them off while threatening to kill anyone who approached. After an hour, the police finally overpowered him. Doheny was declared insane by doctors and committed to an asylum in Danvers, Massachusetts.
