"Lin, how is your work over there?" The next morning, in the office of the North District Bureau, Lin Xiuyi received a call from Sean.

"It's just the beginning!" Lin Xiuyi replied coldly.

"Hey, man, don't be angry! You know, we're partners, so sometimes we have to help each other! You see I've got some things to do, and when I'm done, I'll go back to work with you on the North Precinct Police Department......"

Maybe it's because of the weakness of his heart, Sean's attitude on the phone is very polite. Although Lin Xiuyi came to the United States for training, Sean was not Lin Xiuyi's superior. Even to a certain extent, Sean still has to maintain a good relationship with Lin Xiuyi, because this is related to the cooperation between the American and Japanese police.

"So, you owe me a favor?" Lin Xiuyi's attitude changed, and he suddenly asked.

"Of course, I owe you a big favor!" Sean was relieved when he heard that Lin Xiuyi was not angry.

"Sean, I have a little thing I want to ask you for a favor! I have a friend's daughter who has run away from home, if you can, I would like to ask you to help me ask!" Lin Xiuyi took the opportunity to mention to Sean what Melanie asked him about last night. The search for missing persons still depends on the police, but if the FBI can intervene, the police may take it more seriously.

"No problem, I'll say hello to the North Precinct Police Department!" Sean happily agreed.

After the call, Lin Xiu continued his work of sorting out the case file with satisfaction. That's all there is to it, and with the FBI's involvement, the police should devote more resources to investigating Natalie's whereabouts.

Lin Xiuyi casually picked up the next case file, this case file looked a little old, and the cover and the handwriting on it were a little discolored.

"The Green River Murder and Abandoned Corpse Case—1982.8."

Lin Xiu lifted the cover of the case file and began to read the contents carefully.

……

One day in August 1982, Robert, an amateur kayaker, sat in his kayak as usual and paddled down the Green River toward the Seattle suburbs. Just as Robert arrives at his familiar waters as usual, a clump of hair from a floater in the distance catches Robert's attention.

As someone who often engages in water sports in the Green River Basin, it is not uncommon to see some household garbage on the Green River from time to time. Robert often sees all kinds of bulky garbage in Green River, such as worn-out sofas, obsolete furniture, electrical appliances, and dolls used to display clothing in the mall.

Robert paddled in the direction of his hair floating, as he could not tolerate the Green River being polluted by household waste, but as Robert pulled his hair up with his hands, a round and bespectacled human head was suddenly pulled out of the water, and he was so frightened that he almost rolled over the kayak.

Robert retreated the kayak in horror, but his bad luck was clearly not over, and just as Robert had just turned around and tried to flee the scene, his oars suddenly brought up a black human hand, and this time, Robert was simply frightened. He rowed to the shore with all his might, and as soon as he got ashore, he ran to nearby Route 90 to ask for help.

With the help of a kind driver, Robert was taken to the nearest pay phone to call 911.

After receiving the report, the Seattle North District Police Department quickly dispatched a large number of police to the scene of the incident. The police soon fished out two naked teenage girls from the river.

One of the bodies of the two victims was a white girl in her late teens who fell into the river with ropes tied hand and foot and a weight hanging between her legs. Judging from the appearance of the corpse, the decomposition is not serious, but the shocking thing is that the girl's body is covered with bruises and purple scars, which indicates that the girl may have been brutally beaten by the murderer during her lifetime.

The other victim was a black girl, also in her teens, naked, with many battering scars on the surface of her body. The girl's body was not tied, but only a pair of blue jeans tied around her neck. It can be deduced from this that the black girl may have been strangled.

The bodies of the two victims were taken back to the police station for further examination. According to the medical examiner's post-mortem report, the bodies of both victims had signs of hyoid bone rupture and cervical vertebrae dislocation. This means that they all died of mechanical asphyxiation. However, the examination of the superficial wounds of the corpse made the police officers who handled the case gasp.

The bruises and scars on the bodies of the two girls showed signs of healing to varying degrees, and some of the bruises and scars were probably caused a month ago, which means that the two unfortunate girls were likely to have been tortured by the suspect for up to a month before their deaths.

There were obvious signs of sexual assault on the girl's body, but the killer was very experienced in washing the victim's lower body with bleach. So it is no longer possible to discern the blood type of the murderer.

Reading this, Lin Xiuyi couldn't help but feel a little regretful, there was no mature DNA identification technology in 1982. So the police can only tell the killer's blood type from the killer's body fluids. However, even with the sophisticated DNA identification technology at the time, the police technicians were still powerless because the bleach would destroy the DNA in the killer's body fluids.

Two corpses covered in bruises, a few ropes that were everywhere, a weight to hold the corpse in place, and the murderer's DNA that could not be extracted. This is the only thing left by the murderer back then, and there are no other clues.

In most murder cases, the police can investigate by investigating the social connections of the deceased. Because more than 80 percent of the murder victims and victims are known. So the first thing the police have to do is to investigate the true identities of the two murdered girls.

After investigation and visits by the police, it took more than a month to finally determine the identities of the two girls.

The white girl named Winnie, who was only 16 years old when she was killed, lived in the suburbs of Seattle before her death, and a few months before she was killed, Winnie chose to run away from home because of a verbal altercation with her mother. After that, he disappeared. The black girl named Linnie was only 14 years old when she was killed, her mother died of a drug overdose, and her father was serving a prison sentence in Seattle. Lin Ni was taken care of by her aunt before her death, but according to the investigation, Lin Ni's relationship with her aunt's family was not good, and she also chose to run away from home half a year before she was killed because of conflicts with her aunt's family......
