A one-hit kill!
At least in Zheng Fenyong's view, the testimony presented by Dr. Ding was a true strike that could kill the defense's case!
First, he was himself a technical professional, an expert witness.
Next, he could prove that there was an error in the DNA report from 20 years ago.
Last, and most crucial, there was a problem with the evidence itself—the DNA comparison results were totally different from those of Mr. Li.
This last point was key.
"Dr. Ding, please repeat that, I'm afraid some people didn't hear it clearly!"
After getting the answer he anticipated, Zheng Fenyong still repeated the question, "Are you saying that the DNA extracted from this single hair is completely different from the DNA of the plaintiff in this case, Mr. Li?"
"Yes, the DNA comparison results show a huge error. Generally speaking, only when the DNA match rate is 99.99% can it prove to be the individual's DNA!"
