The Forensic Doctor Better Than a Detective Chapter 347 - 214: Jiang An’s Ultimate Assist

"You don’t necessarily have the chance to report it unless you write a report letter in prison against ."

While speaking, Li Jian emphasized heavily on the phrase "write a report letter in prison."

Li Jian then continued, "Aren’t you going for an outdoor barbecue this weekend?"

"Do you rember where you bought the charcoal?"

"What’s up?"

"Is there anything wrong with buying charcoal for a barbecue?"

"Of course there’s a connection because Liang Yan and Yang Guang died of carbon monoxide poisoning."

Then, Li Jian stated word by word: "Charcoal is the best source of carbon monoxide."

Upon hearing this, Liu Tie shifted his position and unconsciously moved his hand across the panel.

"I don’t understand what you’re saying?"

"Earlier, I heard they died from alcohol poisoning. How did it suddenly beco carbon monoxide poisoning?"

Li Jian said, "There’s no need for to tell you how we discovered the true cause of death."

"But, I want to tell you one thing."

"The cause of their deaths has been confird, it’s carbon monoxide poisoning."

"The murderer was very cunning, using a thod that defies common sense and typical cri patterns, trying to deceive everyone."

"But now, I’m telling you solemnly."

"In Jiangcheng, this criminal thod won’t work and can’t be hidden."

Li Jian’s words were powerful, and his expression was very serious.

Liu Tie sat there with a blank stare after hearing this.

"Scared?"

"Hearing about carbon monoxide poisoning, did you think your criminal sche was exposed?"

"What should I be afraid of! I don’t have any sche."

"Now, the only thing I wonder is why they died of carbon monoxide poisoning."

"The key is, how is their poisoning death related to our barbecue?"

"On the surface, it doesn’t seem related."

"However, both incidents used the sa dium, which is charcoal."

"Moreover, we searched your balcony and found two-thirds of two boxes of charcoal missing."

"Don’t tell , that two-thirds of the box of charcoal was used in advance."

Instantly, Liu Tie looked up swiftly.

His eyes were full of hatred and anger.

Two minutes later, he said in a deep voice, "Yes."

"I did use a part of the charcoal ahead of ti."

"I was trying to barbecue at ho."

"I did it a few tis in college, but I’m not very skilled, so I wanted to practice at ho first."

"You are lying!"

"Where are the charcoal remains? Where did they go?"

"In the neighborhood’s trash bin, but it’s been days, so they should’ve been cleared."

As soon as he finished speaking, Li Jian harshly said, "You’re lying."

"We didn’t see any tools for using charcoal in your house."

"Even the purchased barbecue grill has no scorch marks from charcoal."

Liu Tie laughed at the corner of his mouth.

"I didn’t use the barbecue grill; I used a steam grate."

"Stead grate?"

"No need to argue further!."

At that mont, Li Jian’s phone rang.

It was Mr. Fu calling.

Li Jian took out his phone and answered it.

"Hello!"

"Captain Li, we’ve retrieved the surveillance of the unit where Liu Tie lives; on the night of the incident, he returned ho around four in the morning."

"Anything else of value?"

"On the day of the incident, he left with a bag in the morning, but what’s inside isn’t clear."

"Okay, I understand."

After hanging up the phone, Li Jian continued to ask, "After you and Li Yong sent her ho, where did you go?"

"We each took a taxi ho."

"What kind of taxi?"

Liu Tie thought for a mont. "It should’ve been a roadside unregistered taxi."

"Where did you get off?"

Liu Tie pretended to think for a while and said, "I apologize. I drank quite a lot that night, so I’m not clear about where exactly I got off."

"When did you return ho?"

"I can’t rember that either, I only know that I woke up the next day in bed."

Li Jian stood up and walked over.

He said clearly, "Since you can’t rember, let tell you."

"That night, you didn’t return ho until around four in the morning."

Li Jian asked, "You left the talent apartnt around 10:30, and returned ho around 4:00, where did you go during those five and a half hours?"

Liu Tie raised his hand and rubbed his forehead.

"I drank a lot then and blacked out completely, I might have slept sowhere and then went back."

"Nonsense! Utter nonsense!"

Seeing his sly expression, Li Jian clenched his fists, eager to unleash his rage.

But he held back in the end.

Then, Li Jian shouted, "I advise you to be honest."

"Confess for leniency, resist for severity."

"If you say nothing, we can still use the evidence in front of us to take you to court."

Seeing Li Jian angry, Liu Tie relaxed even more.

He leaned back in the chair and said, "Take to court? Do you have solid evidence?"

"Isn’t it possible?"

Captain Li Jian’s eyes widened, staring at Liu Tie.

"As the head of the criminal investigation team, I don’t believe I can’t put you behind bars."

After speaking, Liu Tie’s mouth twitched, and he said nothing, just stared straight at Li Jian.

At this mont, Jiang An raised his hand and patted his shoulder.

"Mr. Li, take a break and let ask so questions."

Li Jian nodded lightly.

Then, Jiang An looked up at Liu Tie.

At this mont, Liu Tie had the upper hand, looking like a fearless pig.

Jiang An began asking, "In fact, you are a very cunning person and also ticulous."

"Throughout the case, you executed an unconventional murder thod, killing invisibly."

"However, I think there’s one thing you didn’t consider clearly.

As soon as he finished talking, Liu Tie raised his head and looked at Jiang An.

"After you first sent them ho, you and Li Yong went on to create an alibi."

"But, there’s one thing you overlooked."

"You put the previously obtained key on their shoe cabinet at ho."

"Perhaps, in your view, with the key inside, the house was a closed-off scene, unable to be tampered with."

"Moreover, they drank a lot the day before. Alcohol poisoning death."

Pausing slightly, Jiang An said, "We’ve learned that at the party the night before, you were very active and made Yang Guang drink a lot."

"Therefore, after their deaths, many people thought they had overdrunk that night."

"But, that key betrayed you."

As he spoke, Liu Tie just silently looked at Jiang An, not saying anything.

He was waiting for Jiang An to reveal the key evidence.

Jiang An said, "That night, when you set the charcoal to kill, you had carbon dust on your hands."

"Besides being on your hand, it transferred to the key the mont you opened the door."

Upon hearing this, Liu Tie’s face flashed with dread, recalling the night’s scene.

Then, he glanced at his right hand.

After a slight pause, Jiang An pulled out a set of keys from his pocket.

He said, "Normally when we open locks, we instinctively use our index and thumb to pinch the key to unlock."

"Actually, your behavior precisely left your fingerprint in the form of carbon dust on the key."

Speaking, he took a fingerprint press box and a fingerprint card from the interrogation room drawer.

Imdiately, he said, "If you don’t believe it, let demonstrate."

"To leave a fingerprint mark on this card, one must press the ink box once.

In an instant, Liu Tie’s heart raced, sitting completely still in his chair.
