I suddenly realized that she used my stapler to kill them!

I stared at Caleb in a daze, and he continued. "But it's strange that we didn't find any fingerprints on the stapler.

"And why did the killer deliberately staple the victims' mouths after strangling them?"

I looked up and asked Caleb meaningfully, "Officer Foster, is it possible that the killer bound the mouth first and then strangled the person?"

Caleb looked at me in astonishment. "If the victims were still alive when their mouths were bound, why didn't they call for help?"

I lowered my head in silence, unable to help but think of the screams coming from the opposite dormitory last night.

They were clearly resounding through the sky, but it seemed like I was the only one who could hear them.

"Officer Foster, aren't you curious about how the killer entered the opposite dormitory? Why didn't the surveillance capture the killer?

"Or maybe it did capture them, but you just didn't notice!"

Upon hearing this, Caleb suddenly became interested. He put down the pen he was using to take notes and looked at me puzzled. "Jovie, what do you want to say?"

I took a sip of tea, and a slight smile appeared at the corner of my mouth. "Officer Foster, as I said, you should focus your investigation on my roommate."

Because my roommate, Chloe, was not human!

I could hardly remember when I discovered this thing!

Chloe and I used to have a good relationship. We were in our second year of graduate school and lived in a double room in the graduate student apartment.

So most of the time, we were together.

The close relationship in daily life made it easy for me to notice her abnormality.

She was a typical love-brained person. Once she entered a state of love, she would completely lose herself.

In my impression, she had only had one relationship, which lasted for six years. They were very close.

Her first love was also from our school. I met him twice. He was a clean and good-looking boy.

Just when I thought they were about to meet each other's parents, they suddenly broke up.

Now that I thought about it, it seemed that Chloe's personality changed a lot from that time.

At first, I thought she was just temporarily affected by the aftermath of the breakup, but as time went on, she became more and more abnormal.

I often woke up in the middle of the night and found her standing alone on the balcony, muttering something like a spell.
