Chapter 765 This is impossible!
Everyone regrouped again. This time Aubrey went to the CSI laboratory to monitor the DNA test results. With his communication skills, he should be able to get familiar with Mike Taylor's people quickly. Jiejie Team up with Hannah to investigate new suspects.
Soon Hannah had the results, “According to the Northern Westchester County Housing Authority, 5 months ago Sigby applied to rewire his cafe and I contacted the contractor, A total of about 1 ton of No. 14 wire was used in the project. "
"It seems the time is right," Jack said, "Let's take him back and ask."
Two hours later, a young man with a somewhat panicked expression was invited into the interrogation room.
Hannah and Jiejie were in charge of questioning, while Jack and Jubal were still standing in the observation room separated from the interrogation room by a one-way glass.
Hannah motioned for the other party to sit down, and then went straight to the point, "Mr. Sigbee, why do you need to rewire your cafe?"
"Why?" Kenneth Sigbee was The question was a bit confusing. He thought about countless possibilities along the way, but he didn't expect to be asked such a question after being invited into the interrogation room.
"Because. Because my store was closed for a while, and I want to attract customers back." He explained with a slight stutter.
“People usually sit in coffee shops just for a good Wi-Fi network and to charge their mobile phones. They don’t care if the coffee tastes really good.”
"That makes sense." Jiejie was almost amused by his overly nervous expression. She glanced at each other and then looked at the one-way glass behind her.
The two people behind the glass were both a little disappointed. Jubal was experienced and Jack was proficient in psychology. From his first reaction, he knew they had found the wrong person.
Every criminal who is brought into the interrogation room behaves differently. Some will be angry and try to prove their innocence. Some will pretend to be innocent. Their acting skills are so good that they can even deceive some old people. Some police officers will choose to remain silent and confront.
The reactions of ordinary people are also different. Not everyone who panics has something wrong with him, and not everyone who is awesome and asks to see a lawyer immediately must have a problem.
Situations like Kenneth Sigbee's stunned expression but the ability to give a reasonable explanation immediately usually means that although he is panicked inside, he is not guilty.
The panic in his heart may simply be because he, as a law-abiding citizen, was suddenly invited to the famous FBI. Even if he was facing two beautiful female agents, he would inevitably feel a little uneasy.
Of course, this must be considered in combination with other factors. Currently, there is only one IP address that can connect him to the serial murder case. Considering that he runs a cafe, Hannah and Jiejie are assisting He was invited to the Federal Building in the name of investigation.
But since he is here, and he seems to answer all questions, he must be trying to understand the situation as much as possible.
Hannah continued to ask, "We talked to your contractor and they said that you asked for all the remaining wires to be left behind after the renovation was completed. Why is that?"
Kenneth Sigbee continued to be confused, "Of course, I paid for those. The materials are not cheap. They can always be used for repairs or something in the future."
During subsequent questioning, Kenneth Sigbee stated that he knew nothing about a particular website and did not know what "Incel" actually meant.
Under the pressure of Hannah and Jiejie, he was even willing to hand over his computer to the FBI for inspection without a search warrant.
As expected, the IT department sent a team of technicians to check all the electronic products that could be used to access the Internet in Kenneth Sigbee's cafe and home, but found no clues.
Compared to the discouragement of others, Jack comforted everyone with a smile on his face, "So, the good news is that the suspect may be a customer of the cafe, right?"
Hannah With a depressed face, "Yes, we thought so too, so we asked the technician to check the router, and they did lock a laptop. Every time someone logs in to the website through that IP address, that computer happens to be connected to the Wi-Fi in the store. -Fi. But the problem is that we can't find the computer now."
Each computer has its own unique "electronic fingerprint". The most common one is the MAC code bound to the network card. In theory, after the technician obtains the MAC code of that computer, this computer can be used by other computers. Local login will also get the location immediately.
It is very simple to crack it. Just replace the network card on your computer. This is probably what the murderer did.
“When was the last time that computer was connected to the Internet?” Jack rubbed his chin and fell into thought.
"The day after we found three bodies in Central Park, the murderer should have seen the news reports." Jiejie quickly followed Jack's train of thought.
"So our murderer is as cautious as ever." Jack thought about it and had no choice but to use the last resort, check the surveillance.
“There is no surveillance camera inside the coffee shop, but that doesn’t mean there is none around the coffee shop. Let the technician look nearby to see if there is a surveillance camera facing the door of the coffee shop.”
Hannah’s eyes lit up. , "I remember there is an ATM machine opposite the coffee shop, let's go and do it."
The two girls cheered up again and left together. Jack patted Jubal on the shoulder to express comfort. Since his former partner came to the door today, After the visit, this guy has been wilting.
Just when he was about to say something, Aubrey burst into the office in a hurry, his little eyes were as big as a bell, "You will never expect this"
He picked up a glass of water on the table, no matter whose it was, drank it in one gulp, and then continued, "Forensic scientists did not find any residual DNA in the body, only the lubricant of the condom.
< br>But CSI found a person through DNA matching on the plastic sheet fragments found at the crime scene. You will never guess who he is."
"Who is it? Let's eat and drink," Jack said angrily.
Aubrey turned sharply to look at Jubal, "The Kerry McMay you asked me to check before is the Kerry McMay who should still be in prison!"
"This is absolutely impossible!" Jubal blurted out.
——
Early the next morning, Jack and Jubal rushed to the state prison.
Last night everyone discussed numerous possibilities as to why the DNA of Kerry McMay, who had been imprisoned for three years, appeared at the scene of the latest crime.
There have been cases in the past where prisoners in prisons tried to smuggle their own body fluids out of the prison, and then faked rape and murder scenes in an attempt to confuse the public. However, the uniqueness of DNA evidence has never been overturned.
Kerry McMay only has one biological sister alive. Although rapid testing technology may indeed cause confusion due to genetic similarities between direct relatives, they must at least be of the same gender.
Moreover, CSI was able to extract enough DNA for detection from the little bit of epithelial cell tissue left on the plastic bag fragments found at the scene. It was a bit of a fluke. As long as the body was found one day late, the remaining traces might disappear. .
It is almost impossible and meaningless to forge evidence in this way.
After eliminating all the impossibilities, it seems that there is only one possibility left. The Kerry McMay who has been imprisoned in the state prison for the past three years is not himself.
