Some questions have more than one answer. In fact, as long as it makes sense, they are all answers.

Problem 1: Solution

Veteran's past

Because the topic comes from the FBI, veterans here refer to American soldiers in particular.

In the wars of the last 20 years, the US military has always occupied an absolute advantage in weapons. The only thing that makes it difficult for them to move forward and causes a lot of casualties is the minefield. Veterans are probably mine-clearing engineers. Usually when mines are found, the disposal process is to cover them with military canvas (green) or military uniforms to indicate that there are mines here. If necessary, dig out the mine with a shovel and other mine-clearing tools and put it in an explosion-proof box.

Because the perennial war has caused great psychological trauma to the soldiers, as a result, a tragic accident happened in the army during the veteran's service: a comrade-in-arms of the veteran used the head of his comrade-in-arms who lived together as a mine in his sleepwalking, cut it off with a sapper shovel and put it in the toilet, and covered it with a military uniform to indicate that there was a mine here.

Because the veteran once sleepwalked when he was young, he always subconsciously worried that he would do the same thing one day. Therefore, when he saw the green clothes on the toilet, his potential psychology was aroused again. He made an absurd inference to ordinary people, but he thought it was reasonable: he killed his child in sleepwalking and put his head in the toilet. The "pillow" I saw before is actually the body of a child without a head!

Question 2: Answer

As it is transcontinental country, 7: 20 am may be the local night. Because I am particularly uncomfortable with jet lag, maybe that person has no reaction to jet lag because of his bad eyes. He thought he was too tired and his eyes were almost blind, so he shot himself in despair.

Question 3: Answer

Version 1) The insurance salesman wanted the girl's parents to take out insurance with him, so he killed the girl. The reason why she was naked was to let everyone know that the girl was killed by him, not by accident. The murderer took everything from her, including the key. Then the girl's parents will know that the key has fallen into the hands of the murderer. If the possibility of accidental loss is ruled out, they will be very scared, because the murderer is likely to sneak into their home with the key, and the insurer can persuade them to buy insurance at this time.

Version 2) The little girl is a werewolf. When she saw the moon pattern in the shop assistant's hand, she changed it, and her clothes were torn in the process. After fighting, the salesman killed the young werewolf with his sterling silver pendant and left the humanoid body in the street.

Question 4: Answer

When the girl saw the image of the dog, she found that she knew the dog and its owner (the owner tore himself in half because he didn't want people to know her past), and she always thought that the owner of the dog was dead (the cause of death may be directly caused by the girl). The girl was scared to death because she suddenly found that the owner of the dog was not dead. The owner of the dog is now her boyfriend, whose pursuit is to get back at her. But at that time, girls didn't find this because boys had plastic surgery, so there were only half a photo.

Question 5: Answer

When my son saw the colorless national flag, he thought that his mother had made a cross on the Red Cross, that his mother hated the Red Cross, that his father was a doctor, that he might have been a military doctor before, and that he had participated in World War II. His mixed-race identity was acquired by his mother, and those who have always been proud of mixed-race will inevitably lose their minds.
