Chapter 552 Murder Weapon [2]

Fang Ze pointed to the examination table behind him and said, "I found magnesium ions and calcium ions from the internal tissue of the deceased's wound."

"Don't you think it's strange?"

Hearing this, Tai Wei scratched his head and said, "What's strange?"

When it comes to knowledge of chemistry, it touches his blind spot.

After all, that's what I learned in high school, and I've long forgotten it.

"ion"

On the other hand, Sun Li's eyes narrowed and he said, "Fang team, there are no ions in solids."

"That's right."

Fang Ze nodded.

Such a simple common sense question, any high school student would know.

unless it is an ionic compound.

But those...things are crisp and can't kill people.

Then, where do these magnesium ions and calcium ions come from, there is absolutely no human body.

There must be external reasons.

And there is a high possibility that it was dropped from the murder weapon.

Sun Li frowned and fell into thought.

Fang Ze's test results have brought the current problem into a paradox.

The deceased must have been killed by a blunt weapon, that is, a solid solid.

In hard solids, ions cannot exist.

Either one or the other, but all must be satisfied.

Is there such a possibility? Tai Wei also understood at this time, that is to say, things that could not exist before have now been detected.

Fang Ze glanced at the two of them and said, "Magnesium ions and calcium ions are actually very common."

Hearing this, Tai Wei and Sun Li looked at Fang Ze at the same time.

Fang Ze continued: "When the tap water boils, there will be deposits at the bottom, that is, scale."

"These scales, which are trace minerals, are mainly composed of magnesium and calcium."

"Tap water!"

Sun Li's expression changed.

Fang Ze nodded and said, "Yes, tap water."

"Also, I also detected chloride ions from the wound tissue."

"You should know that tap water is disinfected."

"The disinfectant ingredient is sodium chloride sodium chloride."

"While these chloride ions are negligible, they are real."

Hearing this, Sun Li subconsciously said, "That is to say, the murder weapon is tap water."

"Um."

Fang Ze nodded and said, "The tap water that has been frozen at low temperature is also called ice cubes."

"I don't need to say more about the hardness of the ice cubes"

"It's okay to kill someone if you punch a vulnerable part of the body."

Tai Wei listens to the two

He opened his eyes wide and said, "Guo Peng smashed Zhang Mao to death with an ice cube!"

Fang Ze said calmly: "There is only one possibility."

"Depend on!"

The next moment, Tai Wei smashed his fist on the corpse stage and said angrily, "No wonder I haven't been able to find the murder weapon!"

"This thing, after melting, evaporates into air, who can find it!"

"asshole!"

At the end, Tai Wei scolded directly.

That kid Guo Peng really knows how to choose a weapon.

As long as the body was not found until the ice melted.

Then, it is impossible for anyone to know what the murder weapon was.
