章 163: THE ART OF FINGERPRINTING

"Now look at these."

As she said that, Santina put out three photographic negatives and slid them closer to the envelope.

This was for them to take a closer look at it, all together, and compared them with one another a lot easier.

These photographic negatives came from the first victims of the serial killing case occurring at District 12

However, his surprise did not just end there. Because when Mikael looked closely at the grooves at the negative, he then soon noted that they actually had a striking resemblance to the lines on the adhesive of the envelope.
