When Tamesaburo and others came to Serizawa's room to see what was going on, there was a pool of blood inside, Hirayama's head was severed from his body, and Oume, who was sleeping with Serizawa, lay covered in blood, wearing only her yumoji and almost totally naked (it is not that she had a sexual relationship with Serizawa that night, and it is said that because Serizawa, being completely drunk, complained of being cold, so she put her dress over him and tried to warm him with her body. On the night of this incident, it had been raining since daytime, and the temperature was low).
為三郎たちが芹沢の部屋へ様子を見に行くと、中は血の海で平山の首は胴から離れ、芹沢と寝ていたお梅は湯文字一枚をつけただけのほとんど全裸（この晩は芹澤と情交があったわけではなく、泥酔した芹澤がしきりに寒がるために自分の着衣も着せ掛けてやった上で肌で温めていたためだという。事件当夜は日中から雨天であり、ただでさえ気温は低めだった）で血だらけで倒れていた。
