Although Czolgosz repeatedly denied Goldman's involvement, the police held her in close custody, subjecting her to what she called the "third degree".[67] She explained her housemates' distrust of Czolgosz, and it became clear that she had not had any significant contact with the attacker. No evidence was found linking Goldman to the attack, and she was released after two weeks of detention. Before McKinley died, Goldman offered to provide nursing care, referring to him as "merely a human being".[68] Czolgosz, despite considerable evidence of mental illness, was convicted of murder and executed.[69]
