After amnesia, I became a forensic doctor

Chapter 383 The Biggest Suspect 2
"Recently, a few days ago..."

Su Jin raised her head, exchanged a glance with Shan Chenxun, and asked again, "Are all the barrels here?"

Master Liu took a look, "They should all be there..."

He wasn't sure, and besides, he didn't usually pay attention to these details.

"Not sure?" Shan Chenxun frowned.

Master Liu shook his head: "I have to ask Manager Qin, he is responsible, he should know."

"When will Manager Qin come back?" Yuan Ke walked over with a notebook.

"It is estimated that it will take another two days. This time the invitation is longer. Cheng Fangfang is in charge of his work."

"Cheng Fangfang? Manager Yin trusts her..." Yuan Ke said casually.

"How can such a small matter need to be appointed by Manager Yin? Manager Qin has the right to hand it over to whoever he wants! Fang Fang is very popular, let alone Manager Qin, everyone will turn to her for anything..."

Master Liu talked eloquently, and his words were full of admiration for Cheng Fangfang, "Fang Fang is diligent and efficient. Manager Qin entrusts her with any important work. Every time she is praised by customers, almost Top [-] employees every year! Excellent representative of our cleaning department!"

Shan Chenxun signaled to Yuan Ke to continue questioning her, while he walked back to Su Jin's side.

The man asked in a low voice, "Can this material hold sulfuric acid?"

"Iron is of course no problem." Su Jin explained, "The reaction between iron and sulfuric acid will form a protective substance on the surface to prevent corrosion. In addition to ceramics, glass and other utensils, iron containers are also better tools for storing sulfuric acid."

"A barrel is about four or five catties." Shan Chenxun weighed it, "It's not a problem to put a dozen bottles on the work truck, not to mention that there are towels covering it, so it won't be eye-catching at all."

Su Jin looked at the work car and said in a low voice, "Just find the evidence that Cheng Fangfang appeared on August 8..."

Shan Chenxun put down the bucket silently without saying a word with a sullen face.

After the inquiry, the three returned to the meeting room.

Soon, Lao Yang and others also came back, and they didn't find anything suspicious.

"Why isn't surveillance installed in the guest room corridor?" Yuan Ke questioned.

"It is installed at the gate and in the elevator, but it is not installed in other places, saying that it is to protect the privacy of guests." Gao Shan explained.

"Didn't Cheng Fangfang be found in the monitoring?" Seeing Gao Shan nod, Yuan Ke continued: "Since no one was found, she shouldn't have done it, right? Do you think, if Cheng Fangfang killed Anna, what was her purpose? It must be to avenge her son. But she just found out about her son being violated, which doesn't make sense..."

"Xiao Yuan, you've made progress!" Lao Yang praised her and gave her a thumbs up.

"So, maybe Cheng Fangfang's reaction was fake? She already knew about her son's assault?" Li Bai recalled how Cheng Fangfang cried two hours ago, and he couldn't tell if it was fake.

Shan Chenxun knocked on the table, "Don't make random guesses, investigate the case and tell the evidence."

"Yes." Li Bai nodded without making another sound.

The meeting room fell silent, and within a few minutes, Shan Chenxun received a call from Gu Sir, who told him, "Forensic doctor Su took a sample of sulfuric acid in the bathtub for me. After testing, it was found that in addition to sulfuric acid and a small amount of water, there was also Some chemical ingredients, substances that are mainly used to clean dirt."

"detergent?"

"Yes, it's the type of ingredient that's found in heavy-duty cleaners that remove grease."

"Hmm...Understood." Shan Chenxun's face was solemn, and the coldness in his eyes was spreading.

He picked up the line and remained silent for a long time.
