Organic compounds such as aromatic hydrocarbons can stimulate sensory cells to cause a certain kind of pleasure, for example, many people think they like to smell gasoline because it contains these ingredients.

So when it was difficult to obtain the poison, this kind of thing became a substitute, which was once all the rage in Bend, and then introduced to Seris.

Later, in poor areas such as Southeast Asia and Latin America, especially among children, such behaviour became widespread.

Because after inhaling these volatile organic solvents, which are called "VOS-volatile organic solvents", people will have a certain appetite and can resist hunger and cold.

This group of people is easy to distinguish because long-term exposure to such fat-soluble volatiles can cause eczema in their mouth and nose.

"Long-term VOS use can lead to apathy, which may explain why the killer acted so brutally and violently."

"Where did the murderer enter the house?" Rosie asked.

"Here." Detective Daniels took two quick steps and opened a door that led to the semi-basement.

"This is their laundry room, and there is an unlocked window in it."

Rosie pointed to the electric iron on the table, "Apparently the murder weapon was also found in it." ”

"Excessive killing, full of violence, random selection of murder weapons, but methodical, following a set of fixed procedures after the murder, washing himself, rummaging through his belongings, eating, sleeping in his bed, this is a calm madman."

"Can you explain why he left these clothes?" Detective Daniels pulled out another large bag of evidence.

Rosie looked surprised, "His clothes? His own? ”

"Yes." Detective Daniels crouched down in front of the humanoid imprint drawn on the carpet and explained, "The male deceased, the male owner of the family, was found with the clothes draped over his chest and his pants over his legs. ”

"This detail was not recorded in the previous case, and this is the first time we have heard of it." Jack opened the bag and examined the dirty laundry, revealing large mud spots on his trouser legs.

"Why do you want to cover the body?" Rossi thoughtfully, "The murderer changed into the clean clothes of the master's house, slept in their comfortable bed, and covered his own dirty clothes over the male victim. ”

"Some form of empathy?" Jack answered.

Rosie nodded, "If you want to be recognized for your equal status, everything this family has is what he doesn't have, and he is dissatisfied with his living state, but he can't do anything about it."

So his way of comforting himself is to destroy other people's lives and pretend to be in them, which explains why he still stays in the house for so long after killing people and taking money, and he needs time to feel at home. ”

Jack feels that the difficulty of this case does not lie in the psychological profile of the suspect, and even he has a hunch that the police will soon be able to confirm the identity of the suspect, and the real difficulty of the case lies in how to find a murderer who is wandering around as soon as possible.

Detective Daniels had been nodding his head frequently when he heard another question pop up here.

"How did a homeless homeless man with no transportation manage to move around Central California so quickly? No matter how kind a driver is, he won't just let a stinky homeless man hitchhike. ”

"Maybe finding his way around will lead us to this guy, Jack, fill up your new car with gas, and we'll walk around Highway 99 and maybe open up ideas." Rosie smiled.

——

"You're now located in the Central Basin, which has a hot and arid climate, but at the same time has excellent irrigation conditions from the snowmelt of the surrounding snow-capped mountains, and is the most important agricultural region in the whole of California.

Citrus production here accounts for 70% of the entire federation, wheat production accounts for 40%, and there are plenty of other fruits and vegetables. ”

Little Encyclopedia Rad's words on the phone were endless, and Jack looked at the endless farmland and ditches in front of him and sighed in his heart, what is the Chosen Land, this is the Chosen Land.

They drove along Highway 99 for most of the day, and Jack was an eye-opener, and it was a different scene from the meadows he had seen in Texas.

After artificial reclamation, the feeling of being connected and boundless is even more shocking, and there is a sense of accomplishment after human beings conquer and transform nature.

"Obviously, we've found the suspect's vehicle in California, and he did commit the crime along Highway 99, but not because of it." Rossi said, looking at the railway line not far from the road.

"What do you mean?" Red, who was on the phone, was a little confused and raised his voice slightly.

"Trains, freight trains." Jack and Emily spoke in unison.

At the same time, a train dozens of cars long just passed by, and the wheels ran over the overwhelmed tracks, making a rumbling crash.

"I think we're going to speed things up, and with the rate of federal freight trains derailing at least three times a day, I'm worried that the killer will die from the derailment of the carriage before we can find him."

Jack teased with a little malice.

Nearly all freight rail lines in the United States are privately owned, and the freight rail industry in the country has been largely unregulated since Congress introduced the Sturges Act in 1980, which deregulated the rail industry.

In contrast, the passenger train industry, including the subway, is monopolized by the state-owned National Railroad Passenger Corporation (Amtrak), and although the safety and sanitation conditions in the subway stations are often criticized, the accident rate has remained low.

After a night's rest in a predominantly agricultural town, the trio set off again the next day, this time heading straight to the nearest freight station and contacting a person in charge.

A Mediterranean-haired, pot-bellied white, middle-aged railroad cop received three FBIs.

"We suspect that the suspect is traveling around on a freight train, and his target is a half-day walk from homes not far from the tracks."

After listening to Jack's intentions, the bald uncle looked helpless.

"The bulls and the nomads don't usually meet, and I probably won't be able to help them much."

Emily didn't understand and asked, "What are bulls and vagrants?" ”

The bald uncle shrugged his shoulders and led the three of them along the crooked railroad tracks.

"They call us Railroad Patrolmen Bulls, and we call them Bos, short for Hobos."

"You mean you rarely see those unemployed vagrants who hitchhiker?" Rosie asked, confused.

The bald uncle smiled and shook his head, and said hello to a few railroad workers in orange safety suits, almost all of whom were colored, passing by.

"I've seen a lot, but I've barely dealt with them, and to be honest, I'm just an armed scarecrow, and those things will run away when they see me."
