The middle-aged waitress gritted her teeth and sneered: "Okay, I want to hear what your so-called evidence is!" ”

All of them also held their breath.

He Zheng glanced at her coldly and spoke slowly.

"First of all, you're in charge of cleaning the countertops, so you can walk around the store without attracting other people's attention."

"And you deliberately destroyed the circuit in order not to be caught by the surveillance, you know, the store manager will not think of restarting the monitoring as soon as possible."

"Then, by packing up your things, you walk to the next table where the other person is......"

The middle-aged waitress's face changed drastically, and she interrupted him almost with a roar: "Nonsense! Can you count this as evidence? It's just your subjective speculation! ”

"What are you anxious about?" He Zheng's tone was cold, "I haven't talked about the most critical part yet." ”

Everyone was curious and listened intently.

"You reached into your pocket and dialed the victim's number in your phone, and of course, your phone was muted, including the sound of the call."

"You take the opportunity to drop cyanide into her cup while the victim turns around to get her phone."

"At that time, the lights were dim, and you used your body to block it, and you practiced the movements many times, and the speed was very fast. So no one notices your unusual behavior. ”

"You put cyanide in your cup and leave as if nothing happened, and the victim drank his coffee without knowing it. Moreover, the bitter taste of the black coffee just masked the bitter almond taste of cyanide, and she drank the highly toxic chemical in this way......

The middle-aged waitress's body began to tremble.

Despite the low air conditioning in the café, everyone could see that sweat was oozing from her forehead.

He Zheng's eyes were cold, staring at her, and he said word by word: "And the biggest evidence is ......"

"If I'm not mistaken, you still have a phone in your pocket that you didn't have time to delete your call history...... Just take it out and compare the first number with the victim's mobile phone number. ”

The middle-aged waitress's face turned completely white.

At this moment, the sirens of police cars and ambulances sounded from a distance, and they approached quickly.

The middle-aged waitress suddenly sat down on the ground, and her whole body was depressed.

"Why...... You can know why this is the case...... Why? ”

She only felt that her plan was almost seamless, and even if the police came, they would not suspect her.

But why is such a perfect plan so easily seen by this man?

The corners of her mouth twitched, and she suddenly screamed bitterly: "She should die, she should die!" ”

"Mu Yongkang killed my husband and my son, and I want him to taste the pain of losing his own child! But why is this happening...... Why ......"

He Zheng didn't even look at her, but said lightly: "I don't care why you killed her, you better stay and talk to the police." ”

At this moment, Xu Yancheng walked over, unbuttoned the collar of his shirt, and wiped his sweat: "Fortunately, I rescued her in time, and now she is out of danger." If you send it to the hospital for further treatment, it should not be a big problem. ”

When the middle-aged waitress heard this, her expression was almost crazy: "Why? Isn't cyanide the fastest poison to kill? Why can you still save her?! ”

Xu Yancheng glanced at her, put his hands in his pockets lazily, hooked the corners of his lips and said, "I, but I am the best forensic doctor in the whole country." ”
