Hans Geoffrey said he fell asleep at the time of the incident and knew nothing.
Such an answer was of no use to Purple Summers.
"What time did you go to sleep?" Purple Summers asked.
Hans Geoffrey said, "Nine o'clock... or around nine-thirty, I can't remember clearly. I had a little to drink, suddenly felt very sleepy, and went to bed early."
"You drank alone at home?"
"I have a habit of drinking half a glass of whiskey every night."
Purple Summers furrowed her brows and said, "Let's make an assumption now. Assume there's a person who has seen your chat records and hid in your house without you noticing. This person knows your habits, knows you drink, so they put sleeping pills in your drink. When you went to rest on the second floor, this person committed a murder in the basement storage room, found your car keys, put the body in your trunk, and left during the day amidst the chaos."
