"I know who the killer is." Ling Yi hurriedly ran into the bureau, "Call up all the information of male cleaners over the age of fifty in this area to see who has the experience of joining the army." ”

"You're saying the killer was a cleaner? Could it be a mistake? Big A was so shocked that he almost burned his mouth with a cigarette. No, in his impression, the cleaners are all simple uncles and aunts, and they can't fight with the cold-blooded murderer.

"It is likely that the killer hid the sniper rifle in a movable dumpster, and that he was wearing a cleaner's outfit, no one would suspect it."

"Okay, I'll check it out."

……

Fifteen minutes later.

"It was found that there are a total of 20 cleaners in this area, and there are eight men around the age of 50, and the information is all here."

Ling Yi stared at Big A's computer screen.

"No. 1, Yang Qing, the ...... of the city"

"No. 2, Fang Shan, age fifty-four......"

"No. 3, Chen Feng ......"

"Stop!" Ling Yi locked the screen, and the bald man with a long scar on his face, his dark eyes sank. "Get his details."

"How do you know it's him?" Xiaomei asked curiously.

"Intuition."

“……”

"There you go. Chen Feng, 55 years old this year, a native of this city, once served in Unit 923 as a sniper when he was young. His wife divorced him after he retired, and his children had little relationship with him, and they all moved to H City to hide from him, and he had no other relatives. He used to work as a security guard and a janitor, but he didn't work long, he clashed with his colleagues or leaders, and he was a violent person. In February of this year, he started working as a cleaner. ”

"The first shooting happened in February!" Big A's cousin, little A with a mustache shouted.

"It all matches, it's him!"

Ling nodded. "There have been a number of cases abroad in which retired military personnel have turned homicidal maniacs, such as former U.S. Marine Charles Whiteman, who later became known as the Texas Clock Tower Sniper. He shot and killed more than 10 people and wounded 30 others in 90 minutes on August 1, 1966, before being shot dead by the police. That massacre was planned with the utmost dispassione. ”

"This Chen Feng also committed a crime in a planned way?"

"Well, his modus operandi was very straightforward, and there was no evidence left at the scene, indicating that he knew exactly what he was doing. After retiring from the army, he felt that he was indignant that he had been treated unequally, and he could not adapt to society, so he resorted to crazy revenge. ”

"Great God, you are too good, you know intuitively that Chen Feng has a problem, and you are worthy of our FTK's Sherlock Holmes!" Little beauty eyes worship.

"People have studied a lot of cases and accumulated experience, okay, you think Sherlock Holmes is so good."

Big A immediately called the Health Administration, "I found it, now it's Chen Feng's turn to be on duty." ”

"He is likely to commit another crime, so arrest him quickly." Ling Yi took out the gun in the drawer and was the first to rush out.

……

The team members launched a carpet hunt around the Star Palace.

Ling Yi ran sweating profusely and panting, "Did you find it?" ”

"Nope." The big A on the other side of the headset spitted, "Then the bastard won't run away, right?" ”

"No, serial murderers will never stop committing crimes until they are arrested or killed. Keep looking! ”

The next second, a figure in a yellow cleaner's vest broke into her eyes, and a strong man was pulling out a black sniper rifle from a trash can and aiming it at the fountain.
