Why did Lin Xiuyi dare to conclude that the van he encountered on the road was the car of the Green River Killer? First of all, judging from the temperature of the coffee in the cup, Melanie had not been away for a long time. Secondly, from the location of Melanie's house, although it belongs to the urban area, it is still a residential area, and most of the surrounding houses are independent wooden houses. And at that time, there weren't many cars on the roads around Melanie's house, because it was a low-density residential area rather than the main road of the city. So the appearance of a van here, in fact, is very conspicuous.

Now Lin Xiuyi's biggest hope is the two coffee cups on the coffee table. These two cups of coffee were apparently used by Melanie to entertain the Green River Killer. It is likely that the Green River Killer deceived Melanie's trust by falsely claiming to know Natalie's whereabouts. Melanie unsuspectingly lets the Green River Killer into the house and serves him coffee. The Green River Killer then somehow subdued Melanie and put her in the van.

The entire criminal process was executed cleanly, but the time was still too short, and there was a high probability that there would be omissions. Such as leaving some fingerprints on the teacup, or residual saliva left on the cup when drinking coffee. Although it is not known that the cup belongs to Melanie, the police can extract the DNA of Melanie and Natalie on the comb or toothbrush in the bathroom for comparison, and if the DNA of a third person other than the two can be detected, it must be the Green River Killer.

Barney's test results will not be available until at least tomorrow, and just after Shaun reported the situation of the white van to the North Precinct Police Department and the FBI, Sean has received some information from the Seattle police about the white van that once appeared on Mayflower Street during this time. A total of three suspicious white vans were found by the North Precinct Police Station from road surveillance. Videos of the three cars were uploaded to Sean's mobile phone one after another.

"Lin, come and take a look at this!" After Shawn received the film, he found Lin Xiuyi with his fingers, and the two recognized the van that almost collided with them just now by impression.

"Sean, this is the car! Notify the North Precinct Police Department to find the whereabouts of this car. Lin Xiuyi's depressed mood was finally alleviated, and now that there is a video of the car, it should not be difficult to obtain the registration information of the car from it, and there is finally another clue.

After Sean and Lin Xiuyi confirmed the video of the car, they immediately contacted the North District Police Department. At the same time, the video was transmitted to the FBI's crime lab. Technician Matthew was there to carry out the restoration. Matthew processes images much faster than detecting DNA. In just about ten minutes, Lin Xiuyi got all the registration information of this van.

To Lin Xiuyi's surprise, the truck was actually registered in Idaho. Lin Xiuyi and Sean really didn't expect that it would be such a result.

Idaho is located east of the HSD state where Seattle is located, and borders the HSD state. If the Green River Killer was driving an Idaho-affiliated van, does that mean the Green River Killer was from Idaho or had lived in Idaho?

Is that why the Green River Killer hasn't committed a crime for 35 years?

"Contact the Idaho FBI Bureau to see if there have been any murders similar to the Green River killers in the past thirty-five years, and if so, get the information over as soon as possible!"

What Lin Xiuyi said was exactly what Sean thought. He couldn't figure out why the Green River Killer would commit another crime after years of silence. Now a registration in Idaho points them to a new lead. Is it because the Green River Killer settled in a neighboring state, and has he been committing crimes in Idaho for the past thirty-five years?

Melanie's disappearance suddenly brought Lin Xiuyi a lot of new clues. At the same time, it also brought Lin Xiuyi more pressure. Now time is Lin Xiuyi's biggest obstacle, and the Green River Killer has taken the way of kidnapping rather than killing Melanie directly on the spot. Lin Xiuyi didn't know what kind of intentions he had, but Lin Xiuyi knew that at least the Green River Killer thought that Melanie still had use value. What is Melanie's worth?

Thinking about that poster, the Green River Killer must have seen that poster to find Melanie. This also means that the Green River Killer is actually concerned about Melanie's missing daughter, Natalie. So is it possible to think of it this way, the real intention of the Green River Killer to kidnap Melanie is actually for Natalie.

Thinking of this, a bold idea suddenly appeared in Lin Xiuyi's mind. Could it be that the Green River Killer is looking for Natalie. For Natalie's sake, the Green River Killer even abandoned his old proven criminal methods and switched to a burglary kidnapping during the day. Why Natalie deserves the attention of the Green River Killer is difficult to understand is because Natalie knows some information and details about the Green River Killer.

Lin Xiuyi stood on the grass outside Melanie's house, and the associations in his mind became richer and richer. All along, Lin Xiuyi thought that Natalie had fallen into the hands of the Green River Killer. Now it seems that it is very likely that Natalie escaped from the Green River Killer. There's a good chance she's one of the few people who's seen the Green River Killer......

"Sean, let's go to the North Precinct Police Department. I think we have something to do!" After Lin Xiu greeted them one by one, Sean followed Lin Xiuyi back to the car without saying a word. As soon as Lin Xiu started the car, he began to tell Sean some of the ideas he had just thought of, little by little.

"So Lin, now we're in a race against the Green River Killer to find the missing Natalie sooner. As long as we find Natalie first, we can rely on the clues provided by Natalie to find the Green River Killer......"

Sean re-said Lin Xiuyi's meaning in his own words, and Lin Xiu nodded to affirm Sean's understanding. This case originally started with the investigation of Natalie's disappearance, but now it has come full circle and returned to the original starting point.

"Lin, where do you think this Natalie is now, and since he's seen the Green River Killer, why doesn't he seek refuge from the police?" Sean asked curiously.

"I don't know, but I think Natalie may have been stumped by something, so we and the Green River Killer couldn't find him!" Lin Xiuyi said seriously.
