Tokyo Police

Lin Xiuyi now has a general impression of a Green River Killer in his mind. He may own more than one car, and one of them can carry multiple bodies at a time. Because some of the victims were teenagers, they were actually more critical of their customers' choices. Young adults tend to be apprehensive when picking up customers for the first time, so the Green River Killer should at least seem to be inoffensive and generous.

From the three cases discovered so far, Lin Xiuyi found that from the first case in 1982, the Green River Killer had quite mature criminal skills. If you think about it from this point of view, the Green River Killer likely had several less successful crimes before this. If calculated by age, the Green River Killer's first crime is likely to have occurred in the underage stage.

The Green River Killers should have a place where they can hold their prey for a long time, because all the victims have traces of long-term abuse. In addition, there must be a reason why the Green River Killer has such a strong hatred for this particular group of people.

There has never been a natural killer in the world. Mature killing skills require the murderer to keep trying to master it. The reason why the Green River Killer can successfully commit crimes again and again depends on a set of criminal methods that can perfectly avoid the police and FBI technical investigation. Although the police can find a lot of evidence at the crime scene, these evidences can only guide the police to find the identity of the victim, and there are few evidences that can point to the identity of the Green River killer.

If one were to define the Green River Killer according to the binary analysis created by the FBI's Behavioral Sciences Division, he was clearly an organized serial killer. The Green River Killer knows how to plan carefully before taking action. He will choose his prey carefully, coax them into the car with experience, and then slowly torture these poor girls.

Lin Xiuyi had a hunch. He felt that his pursuit of Mary was meaningful, because before Mary was killed, there was still an unsolved mystery waiting for Lin Xiuyi to solve, and that was why Natalie's credit card was in Mary's hands. .

It's a pity that the provocation of the Green River Killer disrupted Lin Xiuyi's search plan, and there was not much time left for him. A lust-driven pleasure killer has a negligible crime cooldown. Who knows when the next body will be found, in a day, in two days, in a few hours.

Chief Musk has communicated with the Seattle Police Department. In order to prevent the Green River Killer from succeeding again, the Seattle Police Department agreed to increase the security level of Highway 90 in a short period of time, and will be equipped with patrol cars 24 hours a day on the 90th at night. Patrol on the road. However, this is only an expedient measure, not a cure for the symptoms.

After Sean reported the investigation during this period of time to Director Musk, Director Musk agreed that Sean and Lin Xiuyi would continue to follow the lead of the victim Mary.

According to the surveillance that Lin Xiuyi found at the gas station, in the week before Mary's body was found, she once appeared at a gas station on Highway 90. This was the last time Mary appeared in the public eye. Not long after that, Mary was brutally murdered by the Green River Killer. What the **** happened that week? Lin Xiuyi didn't know.

"Sean, at least we know one thing now, and that is that a week ago, Mary used to spend at the gas station. According to the bill provided by the bank, Mary filled her car with 10 gallons of gas. Now I want to know Mary's How much gas is left in the car, and based on these two conditions, can we calculate how far Mary's car has traveled after filling up the gas?"

Lin Xiuyi took a chance and asked Sean about the gasoline in Mary's car. The gas station Mary used to visit was located on the outskirts of Seattle, and Mary's car was parked within the limits of downtown Seattle. If the gasoline consumption in the car is not much, Lin Xiuyi can roughly give a vehicle's activity radius based on these data. And within this radius, it is very likely to contain the foothold of the Green River Killer.

After hearing Lin Xiuyi explain his thoughts in detail, Sean's frowning brows finally relaxed. Sean quickly reported the matter to Chief Musk. Director Musk made a special trip to call Lin Xiuyi into his office to ask Lin Xiuyi about gasoline.

"Sir Musk, let me ask you a question first, if you were the Green River Killer, would you fuel a car that is about to be abandoned?"

When Lin Xiu asked this question, Director Musk was speechless. Yes, if you had known that the car would be abandoned in the parking lot with the body, then according to the thinking of ordinary people, naturally they would not refuel the car.

"So, sir, we now know that the car once filled up at a gas station on Route 90, and from that time onwards, how far the car has traveled, there is always a part of the journey that hides the Green River Killer Since the Green River Killer drove the body from his hideout to the parking lot there's a good chance he won't notice the change in fuel ~www.wuxiaspot.com~ I think it's the Green River Killer so far One of the few oversights..."

Lin Xiuyi was just halfway through, but Director Musk had already understood the meaning of Lin Xiuyi's explanation. He excitedly stood up from his seat with a rare smile on his face.

"It's amazing, how did you think of it?" Chief Musk patted Lin Xiuyi on the shoulder and praised.

"Sir, Detective Sean and I have been tracking down the whereabouts of a missing girl. I also accidentally discovered the whereabouts of the victim Mary from the surveillance video of the gas station..." Lin Xiuyi said modestly.

……

Half an hour later, the experts from the crime laboratory of the Seattle branch carefully studied the remaining gasoline volume in the fuel tank according to Lin Xiuyi's ideas, and estimated that the gasoline consumed should be about five gallons, or about 19 liters. According to the displacement and fuel consumption of this car, it can travel about 95 to 130 miles, which is about 150 to 200 kilometers.

The next work is entirely a mathematical problem. How to run a distance of 95~130 kilometers on the existing road network between the gas station and the parking lot where the body was found? The place.

Lin Xiuyi didn't stay in the laboratory all the time waiting for the final result. He had to go to a rental car after get off work to pick up the GTR that he had already modified. However, at 10 o'clock in the evening, Lin Xiuyi's mobile phone Received the final results from the crime lab. According to Lin Xiuyi's ideas, the computer successfully compressed the hiding place of the Green River Killer within a 50-square-mile area along Highway 90.
