This soymilk maker is a very common brand, with eye-catching brand logo words on the body.

What attracted Xiao Ran was, of course, not the handwriting of these logos, but the handwriting at the bottom of the soymilk machine, a line the size of a grain of rice: ICBC gifts. The color is about the same as the color of the fuselage, and you can't find it if you don't look closely.

Xiao Ran picked up the soymilk machine, the machine is relatively new, judging by the small print at the bottom, this soymilk machine is very likely, it is a gift that Du Keke got when he went to ICBC not long ago to handle business.

But if Xiao Ran remembers correctly, in the column of bank cards that Zhang Lei sorted out just now, there is no ICBC bank card at all!

"Brother Xiao, what's wrong with this soymilk machine?" He Liang looked at the soymilk machine on tiptoe and asked in a low voice.

Now everyone in the team knows that seven or eight out of ten things that can attract Xiao Ran's attention may contain deep meanings, but what He Liang can't understand is what can be hidden on an ordinary soymilk machine?

Xiao Ran pointed out the small words on the soymilk machine to He Liang, and then went straight to Zhang Lei and asked, "Leizi, is there an ICBC card in Du Keke's bank cards?"

There are so many different bank cards, Zhang Lei didn't remember too clearly, he thought for a while and said, "It seems that there is none, right? ”

As he spoke, he checked the bank card left by Du Keke again, and confirmed that there was no ICBC bank card in Du Keke's relics.

"Could it be that you haven't finished checking yet, and the deceased still has a bank card that hasn't been put with these cards?" Xiao Ran asked again.

Zhang Lei shook his head categorically and said: "Impossible, we have already looked at the corners and corners of this rental house, the relics are here, and the deceased's card and various documents are in this bag, it is impossible to have a bank card that has not been found." ”

"Then there's a problem, it stands to reason that she should still have a bank card. Xiao Ran frowned slightly, and said to himself.

Zhang Lei was stunned when he heard this, and immediately asked, "How do you know that she still has an ICBC card?"

Xiao Ran pointed to the soymilk machine in the kitchen: "I sent it for business at ICBC." - The deceased was a woman who lived alone, and it must have been given to her if she wanted to give it away. Besides, if the machine was given to someone else by ICBC, would someone else give a gift to such a girl with quite good economic conditions?"

"So you suspect that the deceased's death has something to do with that bank card?—— that is to say, this is not a suicide scene, but a murder scene carefully forged by the suspect?" Zhang Lei asked in a low voice with a serious face.

Xiao Ran shook his head slightly: "I can't draw conclusions now, after all, judging from the strangulation marks on the neck of the deceased, it is in line with the characteristics of voluntary hanging, and there are obvious test wounds on the wrists." By the way, what are you investigating on the spot?"

"After our investigation, the door of the deceased's house was locked, there was no sign of violent unlocking, and the key to her door was also found in the deceased's bedroom. And there are no less valuable items such as cash, mobile phones, valuable jewelry, and designer bags, and there are no traces of being turned over at home. After being scanned by the ultraviolet lamp, no abnormal fingerprints or footprints were found. Zhang Lei said.

"yes, I see. ”

Xiao Ran nodded, walked out of the bedroom with his feet raised, and just walked out of the bedroom door, he almost bumped into several comrades from the police station who were helping to carry the body out, and after the deceased was carried away, Xiao Ran found a large physical evidence bag and loaded the soymilk machine to take it back.

After returning to the team, after Xiao Ran submitted the police record, he found He Xiaoli and reported the situation at the scene and his own guesses.

He Xiaoli attached great importance to Xiao Ran's opinion, but because there were no clear clues and evidence to prove that Du Keke was killed by him, she instructed Xiao Ran: "Your intuition has always been very accurate, I believe in you, but we can't file a case because of intuition." And the forensic report will take a while to come out, in this case, you should start with the deceased's bank card and check it. ”

"Not only the bank card, but also the suicide note left by the deceased Du Keke, although the handwriting on the suicide note is very similar to the handwriting on the deceased's post-it note, and the family of the deceased also thinks that it was written by Du Keke, but I look at the suicide note, compared with the handwriting on Du Keke's post-it note, it always feels a little stiff, as if it was deliberately imitated. Xiao Ran added.

"If you want to authenticate the handwriting, you have to send it to the provincial department. He Xiaoli frowned and said.

"Sister He, you forgot, I still have some research on handwriting identification, although I didn't take a professional certificate, but there is no problem to help take a look first. Xiao Ran smiled.

He Xiaoli nodded and said, "Okay, if you feel that there is a problem, go and see it, if you are not afraid to see the problem, you are afraid that you will not be able to see the problem." If the deceased is really killed and we don't see the problem, it will make us feel guilty for the rest of our lives. ”

"Yes!" Xiao Ran replied solemnly.

After leaving He Xiaoli's office, Xiao Ran handed over the matter of checking Du Coco's bank card to Li Fangfang and He Liang, the two masters and apprentices, and he went to the technology center to ask for Du Keke's suicide note and those post-it notes, and studied them carefully.

Handwriting identification is generally divided into four types, one is general handwriting identification, the second is handwriting identification that deliberately changes the shape, the third is imitation handwriting identification, and the fourth is left-handed camouflage handwriting identification.

Xiao Ran first compared and studied the spacing between the words and lines on the suicide note and several post-it notes, the cultural level corresponding to the written words, and the font size.

I have to say that the handwriting size, writing tone, font shape, and interline spacing on the suicide note are really very similar to the handwriting characteristics of Du Keke on the post-it note, and Du Keco's handwriting is very distinctive, beautiful, and very distinctive.

For example, the word 'of' written on the post-it note by Du Keco is completely a small dot with a lying number '3', which can be imagined when Du Keco writes, and the general writing speed is relatively fast.

The writing speed is relatively fast, among which there are many consecutive pens, simple pens, and from these even pen and simple strokes, you can also peek into some of Du Keke's character, so to speak, Du Keke's words are chic and confident, full of the kind of strength that I live by me.

As the saying goes, it's hard to imagine that an independent woman who can write such freely and strongly, would commit suicide because of the loneliness and depression of the night.

And after observing through the microscope, Xiao Ran also made more discoveries.

After enlarging the font, you can see that the words on the Du Coco post-it note have few pauses in the way of writing, and it seems that such ligatures should be written quickly, but under the microscope, it is found that Du Coco is fast and slow.

For example, there is a word 'Yu' on the post-it note and the suicide note, when Du Keke writes on the post-it note, it seems to be written in one stroke, but in fact, when the pen is '亅', she will obviously pause the pen forcefully, and then gently put the pen away.

The word 'Yu' on the suicide note is two horizontal and one vertical hook strokes, without pause, and the pen is light throughout the whole process.

After studying like this, Xiao Ran found that many words on the suicide note, although they looked the same as the words on the post-it note, but after a closer look, the differences in their writing, structure, pen movement, stroke connection, and turning angle characteristics were very obvious!

A person's writing habits cannot be changed, and no matter how similar the imitation is, there are always differences in the gods within it.

Looking at the sincere suicide note, a chill welled up in the depths of Xiao Ran's eyes, and he was now sure that this suicide note was forged by someone else based on Du Keke's notes.

Du Coco's 'suicide', there is definitely something wrong!
