Old Lv's full name was Lv Yajun.
By the time Shen Xin and his partner arrived, he had already finished work and left for the day.
But after a quick phone call, he immediately turned around and came back.
"Fipronil?"
Lv Yajun was a man in his fifties who wore glasses. After hearing the details of the case, his brow furrowed immediately.
He gestured for the two of them to sit.
He was very familiar with Fu Lanting's poisoning case; he had been the one in charge of the toxicology tests back then.
He also knew that Shen Xin's team had reopened the investigation. Ding Yuwei and the others had come to ask him questions more than once.
But he never expected the investigation would now lead to Guo Jinhua.
After a moment of thought, Lv Yajun said, "It should be possible."
"After fipronil enters the body, it rapidly metabolizes into fipronil sulfone and fipronil sulfoxide. Fipronil sulfone is the key target for detection."
