"In recent weeks, three women have been kidnapped and then murdered in various locations in Los Angeles."

Jiejie released several female avatars on the screen, all of which were white women with good faces and temperament.

"Sydney Otto, 23, bank teller, killed 15 days ago; Vicky Hagrid, 39, art teacher, killed six days ago; and Linda Dean, 28, a bartender, who was killed 2 days ago.

The locations of their disappearances are scattered in all corners of Los Angeles, and their social backgrounds are completely different, and the three of them have been abandoned in less than 24 hours from the time they disappeared to the time they were found, and the places where their bodies were dumped were all in public places. ”

"It looks like the killer made no secret of what he did." Emily said.

Jiejie nodded, and then released a photo of the police when the body was found, "Garcia cleaned up the snacks in the refrigerator after sorting out these photos, Jack, you need to replenish the stock as soon as possible." ”

The three corpses that appear on the screen are all barley and wrapped in a blue waterproof membrane.

"Looks like a floating corpse?" Red squinted at the projection on the screen, a little unsure.

The corpse was white, and the skin at the joints was wrinkled with layers of folds, as if it had been soaked in water for many days, but there was no particularly obvious swelling, and it looked different from ordinary floating corpses.

"The dumping site doesn't look like it's on the beach or the river, it's all a garbage dump, is it drowned elsewhere and then transported to the dumping site? Isn't that a bit of an overkill? ”

Jack was puzzled, it was common to dispose of the body after killing people in other ways, but it was relatively rare for the drowned body to be recovered and discarded, and the time of death was so short that it could be said to be unheard of.

"It's not the weirdest part." Jie Jie shook her head and sent the forensic examination report in her hand to everyone.

"They didn't drown."

"Methanol?" Red flipped through the report, surprised.

"Methanol was found in the lobes of each of the deceased's lungs, which means they drowned in methanol!"

Emily held her chin and flipped through the report, "It's different from throwing people directly into the water, if the purpose is to torture the dead, the murderer needs to have a sufficiently secret place. ”

"It's really exciting that Garcia is here." Jiejie shrugged her shoulders and pressed the remote control in her hand, and three photos of the soles of her feet appeared on the screen.

"A piece of skin was removed from the palm of the sole of each deceased's right foot."

"Methanol and skin? What is this guy up to? Even Rosie, the most experienced of the group, frowned.

"Methanol is the simplest saturated monoalcohol, first discovered in dry distilled wood, and is very versatile, pure methanol has only a slight alcohol odor." The small encyclopedia started today's popular science.

"Is this thing poisonous?" When analyzing the case, no one hates Rhett's rambling explanations, of course, provided that they can understand it, for example, now, Emily will take the initiative to ask questions.

"It is one of the most hated fusel alcohols of low toxicity and winemakers, and 5-10 ml of oral administration will make a person unconscious for 8-36 hours.

15 ml can cause retinitis, that is, blindness, within 48 hours, and 30-100 ml, which can cause damage to the central nervous system, leading to respiratory weakness and death. ”

Jack answered directly with a wicked smile on his face, taking Rhett's path, leaving Rhett with no way out.

"The way to detoxify is to drink a lot of spirits with an alcohol content of more than 60%, because methanol itself is not very toxic, but the metabolites formaldehyde and formic acid produced in the human body are highly toxic.

Ethanol, on the other hand, competes with methanol in the liver for alcohol dehydrogenase, giving the body time to eliminate methanol. ”

Red opened his mouth, and the expression on his face was a little aggrieved for a moment.

Emily gives her new landlord a punch and tells him to shut up.

Jack shrugged his shoulders amusedly, "Well, I've only been researching brewing lately, so I've looked up some information, methanol is one of the culprits of hangovers after drinking, so let's go back to Dr. Red and talk about what this stuff is for." ”

Red coughed lightly, gathered his thoughts, and resumed his science time.

"Methanol is used in a wide range of applications, including solvents, antifreeze, polyester raw materials, explosives, and during World War II, the Germans added it to rocket fuel.

It can even be used to make growth promoters for plants, increase crop yields, and of course, the most widely used way to separate other chemicals. ”

"So we can't narrow down the suspects by tracking the purchase history?" Rosie listened dizzily and finally came to this conclusion.

Red hesitated, then nodded, "I think so, even if the murderer needs the amount to soak the entire corpse, it is relatively easy to get it.

Because methanol is also used as a biofuel, California's agriculture is so strong that many people can make it themselves at home. ”

"Perhaps we can focus on the corpse itself for a moment, don't you think it's strange? Isn't it a bit contradictory that all the dead were barley, but no signs of surname infringement were found on their bodies, and that they actually fit the basic public aesthetic? ”

Jack banged on the table and offered a new perspective.

"It's true that even an incompetent like Robert Naper will vent his frustration and frustration on his victims, and in reality he will overkill, just like the 'Boston killer.'"

——

Robert Napper is one of the more inept examples of Scotland Yard in the 90s.

This pervert likes to attack women with children, and the number of victims is as high as 86 people, and Jack has seen one of the cases, which is quite high blood pressure.

In July 1992, a 23-year-old British female model named Rachel Rachel took her two-year-old son, Alex, for a walk in Wimbledon Park in London.

Robert Napper attacked them in broad daylight by a pond where he lifted 2-year-old Alex straight to knock him unconscious, then knocked Rachel down, dragging the mother and son duo into the bushes.

Robert Napper slit his mother's throat in front of two-year-old Alex and then attempted a medical examination, which did not go well for his own reasons.

During this time, Robert Napper used a sharp weapon to stab Rachel Rachel in the body a total of 49 times.

When the police arrived at the scene, they saw Rachel lying in a pool of blood, and young Alex was clutching his disheveled mother and shouting "Wake up, get up, Mom!" ”

He also put a note on his mother's wounds, as if trying to stop her bleeding, and it is said that the Scotland Yard police who saw the scene collapsed on the spot.

It took nearly a decade for Scotland Yard to catch the killer with the help of DNA technology, during which time a homeless man was wrongly wronged, a policewoman suffered from PTSD, and a police cameraman suffered a nervous breakdown.

After a lengthy judicial process, 16 years after Rachel Rachel was killed, he was successfully convicted and imprisoned in a psychiatric hospital for Robert Napper, who was not very clever at the modus operandi.

——

"And then there's this, and the fact that the skin on the soles of the deceased's feet was removed can't be inferred from a sexual point of view, and foot fetishism doesn't seem to be like that?" Emily continued to ask more questions.

Continue to ask for a monthly pass.
