Also mark and parentheses to indicate possible and uncertain, and list them until the death does not look like an accident.

In fact, these things are really like finding a needle in a haystack, but you have to check it, there may be a breakthrough in it.

The next step was to check the express delivery and we got some information. Mrs. Rossi’s advertising letters were relatively easy to find. The letters received by Mrs. Rossi the day before her son’s accident were found by express delivery. There were also Mrs. Miller, Miss Davis, and Mr. Johnson.

Three people who may be related to the victim, and all the express delivery and letters on the day of the accident were also found.

Needless to say, the efficiency of the Federal Bureau of Investigation is quite high.

The four people, including Mrs. Rossi's son, all received "special" letters or express parcels like Mrs. Rossi, and the places where they were sent came from different addresses.

The Federal Bureau of Investigation searched through the local responsible persons. Although the names, ages, genders, and social backgrounds of the senders in these places were different, the only thing they had in common was that they did not know that they had such an entrustment. The pickup times were all the same.

It happens that no one is here, either at work or traveling.

Letters are simple and can be put directly into the mailbox. For express delivery and parcels, you will be contacted by phone, and then the courier will pick it up at the door. When the courier arrives, there will be packed items at the door, with enough money on top.

And there was a small note on it, meaning the extra money should be used as a tip.

The courier will naturally follow the normal process, and there is nothing in it that prohibits express delivery.

Follow these clues, retrieve nearby surveillance videos, and find the people who put them at the door. They all use the same approach to receive orders online. After receiving the express delivery, they go to the designated place according to the specified time, drop off the express delivery and pay the money.

With a note, you can get money ranging from fifty to one hundred dollars.

The money is remitted, and the express delivery sent to them is sent from abroad. There is no need to leave an address there. You only need to pay the freight and have a detailed address of the recipient.

I checked the overseas address according to the waybill of this express company, and after touching it, I couldn't find this person. This is a slum with a mixed population. After asking, I only found out that this person has been renting this small house for more than half a year.

, as for where the person has gone now, no one knows.

The portrait drawn based on the oral description is in a slum that is as densely populated as a hornet's nest. Most of the people there don't even have ID cards, so it is difficult to find them.

After going around, nothing was found, and the clue was broken! Karak threw the folder on the desk angrily. No matter how good-tempered he was, this guy was so angry that he was so cunning.

Xining took the folder and flipped through it: "I didn't expect that the book you received would travel around the world."

If you want to get the new book as soon as possible, you can only buy it in your own country, then send it abroad, and then send it from abroad to the country. The domestic online order picker will place it at the designated location, and the courier will pick it up and then express it to Karak.

.

Karak couldn't help but burst into laughter and felt better. He put his finger to his lips, and after thinking for a while, he came to a conclusion: "No wonder there is a gap in the time when the crime was committed."

Not to mention the time it takes for the items to be on the road, they also need to find a suitable place to put them, and the courier must get the items when the family happens to be away.

The fastest time between crimes was Mrs. Rossi's, which was one month. The reason was that she did not use troublesome parcel delivery, but advertising letters that could be dropped into any mailbox.

The business and company mentioned in the advertising letter that Mrs. Rossi received actually existed. And their advertising letters were printed in large quantities and distributed everywhere, so anyone could get them.

And the overseas package receiver disappeared before Mrs. Rossi's accident, and he didn't even ask for a deposit. This proves that this person had a premonition that he might be traced here before he planned to deal with Mrs. Rossi.

This guy was extremely thoughtful and seemed to have a lot of clues, but when he followed the clues to investigate, all of them were blocked. Karak couldn't help but shake his head, it was difficult to solve.

Karak took a long breath and rubbed his slightly hot face with his hands: "I hope Dr. Brown can research something."

After returning, Karak typed up the application report, which was very efficient and was immediately approved. Some of the things collected in the laboratory have been extracted and sent to Dr. Brown's laboratory.

As expected, Dr. Braun works for the higher authorities, and it is said that the research topics are very close.

Mo Ming: "Use non-toxic things to prepare potions that make people lose their minds and use them to deal with leaders of hostile countries."

Xining...

Mo Ming: "But I didn't use the gene, and the smell is too pungent. It can be said that it is a body odor elimination water and athlete's foot spray that passed the customs, but there is no way to bring it into the conference hall."

Er, that's right. Even if you spray it first, why do you still need to bring the hair in?

Xining licked his face: "Great Mo Mingda, can you remind me a little bit, just a little bit like sesame seeds and mung beans?"

Mo Ming: "Not even half a sesame seed."

Humph, stingy! But I’m used to it.

Turning to the case, Xining had to admire him: "This guy is not only good at genes, drugs, and biology, he also understands psychology."

Insight into people's psychology, so Mrs. Rossi opened this letter among a pile of letters; after Clark received the new book, he opened it on the spot.

Let’s take a look at what other people received: Mr. Johnson, a fitness coach, received a healthy ten-day fat-loss tutorial DVD, Ms. Davis, a white-collar worker in the company, received a trial pack of a new facial mask, and Mrs. Miller, the CEO of the company, received an invitation letter to a charity gala.

Marketing executive Mrs. Rossi's son received a presentation for the investment fair.

Except for Miss Davis, who loves beauty, the other victims are all out of professional necessity. They will open the mailed things and look at them without any suspicion.

She suddenly became a little worried: "Did you remind Dr. Brown?"

Karak responded: "There are plainclothes people near the laboratory. It looks like an ordinary university, but in fact the security is no worse than here. This matter has attracted the attention of the higher-ups."

Xining frowned slightly, and Karak also understood something: "Even if the higher-ups want to take over this case, there is nothing we can do. So far, the higher-ups probably have no way to start, otherwise would these things be found out so quickly?"

There is even information from abroad, which is indeed not easily accessible by the bureau.

Anyway, the mission is to find out the truth, but it doesn’t say whether you want to find out the truth yourself or from above, as long as you find out who did it!

Mo Ming: "It's best if you find out."

What should we do after we find out? Control the other party, let him make something that can control people, and then conquer the world? Assi, I am short-sighted, I just want the body owner to be an agent quietly, and then be promoted to an agent in the future

They grow up, get married and raise offspring, and go through the life journey that most humans must go through.

It's almost time again, so the food cooked in the morning is put away in the evening. It doesn't taste as good as it did at noon, but it's still comparable to the modified takeout outside that has changed its taste.

After eating, I went to bed. In the morning, before I woke up, I was woken up by a call on my mobile phone. Something happened to Dr. Brown...
