Capítulo 26: Chapter 26 Persevere and Redouble Your Efforts

"Who matched the DNA?" Jiang Yuan climbed up from the collapsible bed, took a sip of water, and casually used the remaining water in the cup to wash his face, feeling somewhat more alert afterward.

Wang Zhong chuckled and said, "You seemed pretty confident yesterday."

"They wiped it first," Jiang Yuan replied naturally. In crime scene investigation, being the first to act is definitely an advantage; if done thoroughly enough, there might be nothing left for others to do.

Moreover, whether or not one can wipe and detect DNA is all a matter of probability.

When DNA technology was new, criminals didn't understand it; they'd leave pools of blood at the scene, large amounts of seminal stains on the ground, and tufts of hair on the bed. Naturally, the success rate was high. Nowadays, the truly foolish criminals are becoming fewer, making it not so easy to work with "trace" DNA testing.
