Although it was already late at night, the criminal investigation team's office was still brightly lit, shadows moving back and forth.
The clock on the wall pointed to 2 AM, and everyone was energetically busy.
When the two black lip tissue samples arrived at the laboratory, the on-duty technician immediately started the examination process to extract DNA samples for testing.
At 4:15 AM, the laboratory finally delivered exhilarating news.
A young technician rushed into the task force office, panting heavily, clutching a fresh test report in his hand.
"Mr. Ma, Mr. Wang, the results are out!"
Mr. Ma rubbed his sore eyes, "How is it?"
The technician adjusted his glasses, speaking cautiously, "The DNA from these human substances has a 99.99% match with Li Dong's biological sample."
Mr. Ma gave a knowing smile and waved his hand.
"Zhang, we're all practical people here, no need to be so professional."
"Just tell me directly, did this stuff fall from Li Dong?"
