The police officer believed that no one would enter or leave the murder scene through the window.

Although the apartment floor here is very low, the property management is strict. Security guards often patrol on an electric two-wheeled balance scooter. Every intersection is monitored. It is almost impossible to rob or kill people.

There were no signs of forcibly opening the doors and windows, and Gu Yan was still the most suspected person.

Mu Zi gently opened the drawer of the dressing table. There were some cosmetics and some jewellery in a mess.

The clothes in the bedroom are also scattered and disorderly. The sofa, the foot of the bed, and the hanger are all clothes. There are several shopping bags with new clothes stacked on the wall.

Mu Zi thought: The deceased did not seem to be a tidy person.

There is a big four-door wardrobe in the room.

Because the deceased Wu Xinhan was a model, her clothes were so many that her wardrobe was half full, and the other side was slightly empty, with only a few coats hanging.

Mu Zi picked up a handkerchief from a corner of the wardrobe, rubbed it gently with his fingertips, tilting his head and thinking.

"Is there any problem?" Qu Mingjun came over and asked.

"I don't know." Mu Zi frowned slightly, holding the corner of his handkerchief and whispering, "I just feel that...this thing appears here, there is a sense of violation."

"It's a bit strange..." Qu Mingjun muttered while looking at the handkerchief, "Who knows how to use a handkerchief these days? Don't you just use tissues?"

Mu Zi said: "Some people are more accustomed to handkerchiefs, but...people who are accustomed to handkerchiefs usually don't have only one handkerchief, they should have more than two, so that they can be replaced on weekdays."

She looked around and shrugged, "There is only one handkerchief here."

"Could it be that the murderer stayed?" Qu Mingjun scratched his head, feeling unbelievable, "but the murderer came to kill, why bring a handkerchief?...could it be in the closet? For example...a gift for buying clothes?"

"It's not clear yet." Mu Zi raised his handkerchief and turned to ask the police officer, "Can we take this away?"

The police officer replied kindly: "It is not allowed according to the rules, but Tong Guanshi ordered to make it easier for the two of you. I just go back to the branch to make a report. This place has been searched countless times, and the rest is taken away. Two items should not be a big problem."

If you really want to act according to the rules, let alone take away the evidence at the crime scene, even on-site investigation is not allowed. After all, Qu Mingjun is only a lawyer, not a detective.

Mu Zi put the handkerchief into the ziplock bag and looked around the room again. The exhibits that can be taken are basically recorded in the case file, and there are no valuable discoveries in the room.

They left the apartment, and Mu Zi walked around to the position under the window. There was a flat green belt without any traces of trampling.

She looked up at the nearby tree and couldn't help saying: "The tree here is very tall."

Qu Mingjun had an idea and said, "If the murderer leaves the tree, can't he avoid the surveillance cameras?"

The police officer laughed loudly after hearing this: "Unless he is an acrobat and can't get down from a tree for the rest of his life, otherwise he will still be photographed by surveillance!"

Mu Zi frowned, thought for a while, and asked Qu Mingjun: "Can you climb up?"

Qu Mingjun was stunned: "Me?!"

"Yeah." Mu Zi nodded, "Climb for a try."

There is still some expectation in his eyes.

...

Five minutes later, Qu Mingjun came down from the tree embarrassedly.

The police officer couldn't help but smile: "Lawyer Qu, you must pay more attention to exercise!"

Qu Mingjun blushed, he climbed...about fifty centimeters.

The police officer’s physical fitness is obviously much better than that of Qu Mingjun. He climbed to the height of two floors in one breath, but the trunk is thick and lacks focus. It is not so easy to climb up again. The position where he finally climbed. It's not far from four floors.

"I think, let's check the surveillance video, right?" Qu Mingjun suggested with a wry expression, "It's okay to flip through the trash can..."

Just don't let him climb trees...
