"What unexpected joy?"
From her pocket, Cui Lili pulled out another report. Mr. Zhao reached out for it, but Cui Lili slapped his hand away and glared at him; he didn't dare say anything more.
"Come on, Big Sis, tell us what the unexpected joy is all about."
Cui Lili exhaled, but she couldn't hide the joy on her face.
"The yellow electrical wire with three loops that you sent for testing, I attempted multiple extractions. Surprisingly, on the eleventh extraction, I indeed found a set of male DNA, which, after comparison, turned out to be that of Zhang Yu.
The sampling location was on the wire's metal filament; presumably, he accidentally cut his hand while dismembering the body, or he already had a wound on his hand, which rubbed against this part and was preserved."
"That's incredibly lucky, or rather, Mrs. Cui, you're amazing for doing eleven samplings. Anyone else would have given up by now; it's your attention to detail that did it."
