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?"
