"We sent it over less than two hours ago, and I think the earliest we can expect results is around four o'clock,"

Zhou Ning nodded and looked at Sun Gaotie.

"Gaotie, wait in the testing department later, and let us know as soon as there's any news. Remind Mrs. Cui to be especially careful when collecting samples from the parts of the fishing line without blood—where it's folded. If someone strangled the victim with the fishing line, they might have left DNA. Of course, it's very likely they wore gloves, given the fishing line is so fine and can easily cut."

"The same principle applies to the vaginal swabs. If the nails could scratch, it means no gloves were worn. This is similar to the technique used in the Red Dress Serial Killings. If we find male DNA in the victim's mouth or vagina, we need to compare it with the DNA of Mi Qingzi from the 'Semen Spirit' case."

Sun Gaotie was diligent, carefully jotting down all that Zhou Ning had said before nodding.
