Psychic assistant to the forensic doctor

Chapter 68
The cause of Mu Zhanhua's death was unexpected—he was poisoned to death by rat poison.The burns on his body were caused during his lifetime, that is to say, he died of poisoning during the first aid.

Fire brigade technicians quickly found the source of the fire.There was some residual red powder there, which was confirmed to be red phosphorus after inspection.Soon, they found a small concave-convex mirror on the windowsill.The cause of the fire, as Cheng Jin and the others guessed, was that a concave-convex mirror was used to focus sunlight and ignite red phosphorus.

And they detected that some of the remaining items had paint on them.The general pigments are flammable, which accelerates the spread of the fire.

Obviously, this is a man-made fire, someone deliberately set it on fire.

Fang Rui and the others quickly found a suspicious point. The studio was locked all the time, and Meng Ran didn't have a key. How did she get in and arrange all this?

What is even more puzzling is why Mu Zhanhua died of poisoning?Rat poison is an acute poison, and its effect is short-lived.When Wen Zixian and Su Ye saw him, he was still in good condition, but he was poisoned not long after.So who could have poisoned him in such a short time?

For a while, Meng Ran's suspicion dropped again. If she was really the murderer, then it would be impossible to explain how Mu Zhanhua was poisoned.From this point of view, it is also possible that someone set the fire on purpose to clear Meng Ran of suspicion.

Fang Rui and several technicians checked the suspicious traces around the studio and obtained the surveillance video, intending to use these to find the person who set the fire.

And Cheng Jin conducted a toxicology test on the deceased's personal items, such as water cups, toothbrushes, and breakfast lunch boxes, but found no trace of poison there.

Poisons like rat poison generally only work when taken orally.Then the poison is likely to be in the drinking water or food of the deceased.However, no trace of poison was found in the tableware and water cup of the deceased, indicating that the murderer's method of poisoning was very special.

"Cheng Forensic Doctor, can't you find out how the deceased was poisoned?" Wen Zixian asked.

"Did the deceased take any medicine or health care products?" Cheng Jin frowned slightly as he looked at the death certificate issued by the hospital.

"Yes, the deceased had high blood pressure and was taking some blood pressure-lowering drugs, basically every morning." Wen Zixian's eyes lit up, and she asked, "You mean, the murderer put the poison in capsules and mixed them with In the medicine, let the deceased take it without knowing it?"

"No, this method is too clever." Su Ye beside him sighed, "In this way, the police don't even know when the poison was injected, let alone who the murderer is."

A perfect crime doesn’t necessarily require complex technical means and a “gorgeous” crime scene. Sometimes a very simple design can allow you to achieve your goal. Of course, the premise is that the police you meet are not smart enough.Otherwise, as long as it is a crime, it will definitely leave traces.

Cheng Jin really wanted to tell Su Ye that this kind of method was actually not very clever, because any experienced police officer could think of it, and some mystery novels often described similar killing methods.

"So, the person who poisoned him is someone who can get close to him," Wen Zixian concluded. "Then, Meng Ran is still suspected, because she can also get close to Mu Zhanhua's office."

If this method was used to kill people, then Meng Ran's alibi would not be valid, because the poison could have been placed before she was arrested, and it happened that Mu Zhanhua ate it today.

After a full circle, the suspicion returned to Meng Ran.

"Don't you think it's a coincidence? Hao Wei's phone was dropped and Meng Ran picked it up, so Meng Ran knew about the dirty deal between Chi Li and Mu Zhanhua." Su Ye straightened out his thoughts and found There are too many coincidences.

As the old saying goes, all the coincidences combined are not coincidences.

In fact, Cheng Jin and the others also felt this way, too many coincidences.The most important thing is that they don't think Meng Ran is the person who can design all this, even though she has referred to so many mystery novels.Because the mood of a manic-depressive patient is unstable, there is no way to execute a series of criminal acts so strictly.

"Let's think about it carefully, what is the source of all this?" Su Ye held her chin and thought intently, "It was Meng Ran who discovered the evidence of Chi Li and Mu Zhanhua's pornographic transactions. You said, Hao Wei has so much Such secret information, will it threaten the two deceased? If it were me, I would probably try to blackmail or something."

Su Ye recalled what the deceased's roommate said. It seemed that Chi Li's depression appeared shortly after the competition, and Meng Ran picked up the phone a week ago.This shows that there is more than one person threatening the deceased, and Hao Wei may have used the secret he possessed to threaten the deceased.

"That is to say, that cell phone should be very important to Hao Wei." Wen Zixian recalled Hao Wei's attitude when he mentioned that the cell phone was dropped—it didn't matter. Find the old phone. Could it be that he deliberately let Meng Ran know about it?"

Su Ye frowned slightly. Was Hao Wei, a person who had entered their line of sight but was excluded, related to this case?
