"Look, is this Mao Cuihua?!" Dong Dapeng shouted excitedly as he pointed to the surveillance. After looking for Mao Cuihua for a long time, she was finally found in the surveillance. "Why is there another person next to her?"

This monitor is installed on the ceiling of the waiting hall, although you can only see a distant back on the edge of the monitoring, but the special braiding technique, Liang Xiaojun can recognize it at a glance, it should be Mao Cuihua can't be wrong. Mao Cuihua in the surveillance was not alone, she held the arm of another patient, and the two of them were not fast, walking towards the corner of the waiting hall step by step. "What's in the corner?"

Liang Xiaojun and Dong Dapeng looked at each other for half a second, and suddenly said in unison: "It's an elevator!"

There are a total of six elevators in the elevator room, and after checking the surveillance video in the six elevators one by one, it was found that Mao Cuihua and her family were riding in the No. 3 elevator.

The monitoring in the elevator is clearer, and it can be seen that the person who has been holding her arm in Mao Cuihua's hand is an old lady wearing a hospital gown. The old lady had gray hair and a very thin body, but she always had a kind smile on her face. This old lady Liang Xiaojun recognized it at a glance, it was the Wang Grandma who was basking in the sun on the lawn yesterday, and she wanted to introduce her son to herself.

The two of them walked into the elevator with a smile and a smile, but unfortunately the monitoring in the elevator did not have a sound reception function, and they couldn't hear what they said. When the old lady stood firm, Mao Cuihua pressed the button to close the elevator door, and the number of the floor she chose was neither the ninth floor where she lived nor the eleventh floor where the old lady lived, but ...... Top floor!

Seeing this, Liang Xiaojun's heart "chuckled", and a very bad premonition suddenly enveloped her heart.

"It's strange, what are they doing on the top floor?" Dong Dapeng was on the night shift today, and he only came from home in the evening, and he didn't know about the old lady falling from the building in the afternoon.

But Liang Xiaojun's heart is like a mirror, and she is silently thinking about a question in her heart at this time: Murder requires a motive! If a little girl who was deliberately kidnapped, ravaged, and injured by someone saw the enemy's mother one day, would she be ruthless and take revenge?

There were several people going up and down in the elevator, but Grandma Wang and Mao Cuihua had no intention of going down. As the elevator rose higher and higher, Liang Xiaojun's heart felt more and more cold. She hoped that Grandma Wang could get off the elevator by herself and let Mao Cuihua, a poor girl, clear her suspicions. Unfortunately, things seem to be moving towards the darkest side.

When the top floor arrived, Mao Cuihua helped Grandma Wang down the elevator. Surveillance footage in the corridor outside the elevator showed that they were not going anywhere, but walked into the stairwell step by step. Walk up the stairs to the rooftop of the First People's Hospital!

The time in the surveillance shows that it is about 14:50 a.m., and the time when Liang Xiaojun and Captain Yu found the old lady's body in the parking lot was about 15 o'clock!

Watching the door of the stairwell gradually close, Liang Xiaojun felt that there seemed to be something blocked in her heart, she really didn't want to believe that the poor little sister she had been with and cared for so many days would be a person who ruthlessly pushed the old lady downstairs! Could hatred really make people lose their minds and lose their kindness?

There is no monitoring equipment installed on the rooftop, so what happened to these two people on the rooftop, no third person in the world knows.

Liang Xiaojun blushed and patiently observed the surveillance video of the corridor on the top floor, until the monitoring time showed fifteen:20, Mao Cuihua poked her head out of the stairwell. She walked into the elevator alone and pressed the button on the ninth floor like a nobody.

"She actually went back to the ninth-floor ward?" Liang Xiaojun, who has not been back to the ninth-floor since Grandma Wang fell from the building in the afternoon, was quite surprised, but the surveillance video will not lie, since 3:20 p.m., Mao Cuihua has been staying in the ninth-floor ward, and has never gone out again.

"Dapeng, come with me!" Liang Xiaojun couldn't sit still anymore, and rushed out of the monitoring room. Dong Dapeng hurried and hurried, and finally caught up, he didn't know what kind of evil fire Liang Xiaojun was sending in a daze! He didn't dare to ask more, so he had to follow closely behind.

Taking the elevator to the ninth floor, Liang Xiaojun took three steps and two steps, and pushed open the door of the 901 ward. Mao Cuihua, who she had been looking for for for a long time, was sitting upright on the hospital bed, still nibbling on the apple that Liang Xiaojun bought for her.

"Sister Xiaojun, what's wrong with you?" asked Mao Cuihua with a casual look.

"Mao Cuihua! You're still acting with me! What did you do on the rooftop in the afternoon? Tell me honestly!" Liang Xiaojun couldn't control the anger in her heart anymore, and broke out hysterically.

"What are you talking about? Why can't I understand?"

Liang Xiaojun stepped forward and slapped the apple in Mao Cuihua's hand. "Why are you leading Grandma Wang up to the rooftop? Did you push her downstairs?"

Mao Cuihua, who was exposed to the hole card, flashed a trace of imperceptible anger in her eyes, she climbed down lightly from the hospital bed, picked up the apple that fell on the ground, and said: "This apple is very expensive, when I was in my hometown, I could only eat it during the New Year's holiday." She gently wiped the ash from the apple peel with her sleeve, and took another big bite, greedily chewing the rich juice of the flesh.

"Don't pretend to be crazy and stupid with me! If you don't explain honestly, I'm not polite to you!" The fire in Liang Xiaojun's stomach obviously couldn't be suppressed, and anyone who was teased like this probably wouldn't feel good.

"I didn't...... I really don't have ...... I didn't do anything...... I really didn't do anything......" Mao Cuihua shook her head wildly, throwing all the braids on her head into a mess.

"Dapeng, what are you waiting for, handcuff her!" Liang Xiaojun sharply instructed Dong Dapeng, who was standing at the gate.

But Dong Dapeng didn't go to Mao Cuihua, but walked over to Liang Xiaojun, and whispered in her ear: "Xiaojun, why do I see that her eyes are wrong! Is she sick again?"

Mao Cuihua, who was squatting on the ground, did not look quite right now, and the nervousness, anxiety, restlessness, and panic in her eyes all ran back!
