Hearing Dai Hong's final words, except for Lu Yangcheng and Yi Xiuzhu, who had just been pulled in for reinforcement, everyone else in the room furrowed their brows.
After his death, Yang Yongan's body turned into froth, leaving no trace of his fingerprints, iris patterns, or any other basic biological characteristics.
The man was gone, so what good would fingerprints and the like do?
But as long as there is residual matter, DNA can be detected.
The froth from his corpse was the last bit of Yang Yongan that remained.
The Forensics Department tested the foam and determined that it could not be matched with his pre-existing biological archives, which clearly indicates that DNA had been detected and compared.
The situation was different from Xie Guangkun's case.
Yang Yongan had been incarcerated in the North City Detention Center for half a year.
His identity had been thoroughly confirmed and was beyond question.
