Han Jingshen knew this child, but Yan Hua didn't.

Yan Hua turned around and glanced at Ji Xiaofan and the child, Ji Xiaofan explained at this time:

"This child is the grandson of Ma Xiaohong's mother, Sun Xiulan."

As soon as Ji Xiaofan said this, Yan Hua understood.

Ji Xiaofan's expression is so serious now, he must know something.

Yan Hua nodded, and then said:

"Go ahead."

After waiting for the group to arrive at the police, Han Jingshen was still in the car, and Ji Xiaofan took the child and Yan Hua in.

Regarding this case, the police also investigated similarly.

There were no fingerprints on the murder weapon, so it can be concluded that the murderer wore this glove to hide the fingerprints when he committed the crime, and it was a fatal knife that hit the heart.

This method is generally done by professional killers or people whose strength is very different from Ma Xiaohong, Ma Xiaohong's mother Sun Xiulan is over 50 years old this year, and compared with Ma Xiaohong, she does not have much advantage, so the possibility of Sun Xiulan's murder can basically be ruled out.

Han Jingshen fled, Ji Xiaofan didn't know anything about Han Jingshen's situation in the detention center, so the police didn't know how old he was this year, judging from his size, Han Jingshen was an adult.

So he is more likely than Sun Xiulan.

The police were about to call Yan Hua and ask him to bring Ji Xiaofan back and ask about the specific situation of the person who escaped that day.

At this moment, Yan Hua led Ji Xiaofan in.

At this time, Ji Xiaofan was still followed by a child.

Ji Xiaofan was at the door with the child, but he didn't come in, Yan Hua came in alone and whispered a few words to the staff inside.

Then someone nodded and came out, and after Ji Xiaofan saw it, he pulled the child on the ground at the door and continued to play with the child's marbles.

"It's the same as just now, you win a game with me and give you 10 yuan, I win you, you continue to answer me a question."

The child looked at the policeman standing next to him, and thought that on the train, when the policeman grabbed his grandmother and asked his grandmother to make up the ticket, he had a psychological shadow on the uniformed person and asked Ji Xiaofan:

"You're not going to arrest me, are you?"

"No, I said, I'll send you back later, I won't lie to you."

The kid was already familiar with Ji Xiaofan, so at this time, he believed Ji Xiaofan's words, nodded and continued to play with Ji Xiaofan.

Ji Xiaofan asked the two questions he had just asked again, and the kid answered truthfully.

The two policemen standing in the back were taken aback, they didn't expect it to be like this.

Yan Hua had already said it just now, saying that this child was Sun Xiulan's grandson and Ma Xiaohong's nephew.

Children don't lie, and what he says must have been seen with his own eyes.

And there is a suspicion about Ma Xiaohong's son, if the person was killed by Han Jingshen, how could they have time to deal with Ma Xiaohong's son?

But what the kid said was that the man in black took the kid away, and it made sense.

After knowing such an inside story, he brought Sun Xiulan out of the detention center for a new round of questioning.

After all, Sun Xiulan is just a woman in her 50s with little knowledge, and it is not difficult for the police to ask what to say from her mouth.

Especially now that she has a target, under the offensive of her heart and spirit, Sun Xiulan recruited it at night.

is the same as her grandson said, after she was kicked out by Ma Xiaohong, Sun Xiulan was angry and hateful, and was instigated by the man in black to do something wrong.
