Chapter 47 Concealment

"Knock, knock..."

There was a knocking at the door.

Susan looked toward the entrance, "Come in."

"Creak..." The door opened.

Mary Su from the Scene Investigation Team walked in, "Captain Susan, the crime scene report for last night's illegal entry case is out."

"Thank you for your hard work." Susan took the report, glanced at it, and handed it back, "Hmm, there are quite a few technical terms, let's 'translate' them."

"OK, I'll just go over the key points."

Mary sat down at the conference table and started reading from the report, "First, the study's camera transmitted signals via a wireless device, but we never detected a receiving device. It's quite possible that the culprit noticed and left in advance.

Second, we have collected biological traces from the room, including but not limited to fingerprints, hair, DNA, footprints. However, no biological traces of any suspects were found.
