One night in April this year, the wind and waves on the Yangtze River were calm, but the noisy sirens tore through the quiet river night.

"Comrade policeman, comrade policeman, the safe on my ship has been stolen." An old man with gray hair and nearly sixty years old said to Lao Lu with a sad face. Behind him, there were two middle-aged men, whose expressions were also very depressed and anxious.

Lao Lu said: "Take us to the scene of the theft. ”

The old man took us aboard a small fishing boat, and the diesel engine of the fishing boat rumbled, and the sound of the waves also sounded.

The boat sailed unhurriedly to the center of the river, because in the middle of the Yangtze River, there was a huge sand mining ship, and according to the old man, the safe on this ship was stolen.

As the small fishing boat was moving, I was thinking that this group of thieves was really different, and they would actually steal the sand mining boat in the middle of the river. I estimate that there must be ghosts on this sand mining ship, otherwise how could ordinary thieves choose a sand mining ship as the target?

The boat traveled for about five minutes before finally coming to the side of the sand mining boat. Of course, it is not so easy to board the sand mining ship, because on the side of the ship, there is only one entrance to jump on the sand mining ship, and the rest of the place is high on the side of the ship. Now I'm more certain that the thieves know a lot about the sand mining ship. Otherwise, in the dark of night, when the lights of this sand mining ship are not too bright, it will be difficult to find the entrance and board the ship.

When I got on board, I saw six men standing on the side of the ship, apparently they were the crew members of the ship. Adding the old man before and the two men beside him, there are a total of nine people. In my mind, all nine of them are suspicious.

The old man took us through the plywood, there are a lot of machinery on this floor of the sand mining ship, which should belong to the operation area of the sand mining ship.

Through the narrow metal escalator, we came to the next cabin, which was the crew's accommodation, and I took a look, there were six cabins, two by two, three on the left and three on the left.

The old man quickened his pace, led us into one of the cabins, and then said in a sad tone: "Comrade policeman, this cabin is my quarters, you see in the corner, there used to be a safe, but now it is gone. ”

I asked, "How big is the safe?" How much does it weigh? ”

The old man thought for a moment and said, "This safe is an old-fashioned safe, about sixty centimeters high. I don't know the weight very well, but it must be difficult for an ordinary person to move. I remember that when the safe was placed here, it was carried in by two men in the prime of life, and it was estimated to weigh more than 150 pounds. ”

I walked to the place where I had put the safe before, and there were scratches against the wall, which were exactly sixty centimeters high from the ground, and it seemed that there was nothing wrong with the size described by the old man.

It was from this position that I crouched down and saw obvious scratches on the floor, and they were fresh, probably from the burglar's removal of the safe.

Because the safe is placed in a narrow position, it is difficult to lift it from the spot. The burglar must first move the safe to a position that can be easily lifted to allow for this scuff to be left behind.

Based on this scuff marks, I judged that the weight of the safe was between 80 kg and 90 kg. With such a weight, it is speculated that the perpetrators should be more than two men in their prime.

I stood up and asked the old man, "What's in the safe?" ”

The old man shook his head and said dejectedly: "The main thing is 167,000 yuan in cash and 827 grams of sand gold. ”

I asked, "Where did you get all this cash and shakin?" ”

The old man said: "The money is the money from the sale of sand this month, and the sand gold is the gold that is sifted out of the sand digging this month." ”

I asked, "Can you sift through so much sand gold in a month?" ”

The old man said: "The biggest side business of the sand mining ship is to sift sand gold, and sometimes the money earned is higher than selling sand, but this month is the most sifting out of sand gold in recent years." Originally, I had to hand over the money and sand gold to the owner of the ship in two days, but I didn't expect it to be stolen at this juncture. Ay! ”

I thought about it for a while, and I had a question in my heart, that is, who knew that there was so much money and sand gold in this safe on this ship, then these people's criminal suspicions must be the greatest. However, I haven't said this question for the time being, so as not to startle the snake.

I continued, "When did you find out that the safe was missing?" ”

The old man said, "At about half past nine in the evening." ”

I looked at the time on my phone, it was 10:33 p.m., about an hour after the old man found out about the theft.

I asked, "What were you doing before you found out about the theft?" ”

The old man said, "I'm playing mahjong in the recreation room next to me." ”

I nodded again, then looked at the lock on the cabin and saw that it was intact with no pry marks. So he asked, "When you were playing mahjong next to you, was the hatch of this cabin locked?" ”

The old man's face turned a little pale, and he shook his head in frustration.

I asked, "Why don't you lock the door when you know there are valuables in your room?" ”

The old man hesitated and said, "I...... I used to rarely lock the door when I came out, because ...... Because our sand mining ship is in the center of the Yangtze River, I didn't expect thieves at all, and ...... And even this heavy safe was stolen. ”

Indeed, what the old man said was not unreasonable. Who would have thought that there would be thefts on this sand mining vessel surrounded by water? But now that it's happened, the first thing I suspect is that the people on the boat are guarding the theft.

I asked, "How many employees do you have on board?" ”

The old man said, "There are ten people including me. ”

I said, "Tell me, what were you 10 people doing before the crime?" ”

The old man said: "I and the other five crew members played mahjong in the activity room next to it, two people played with their mobile phones in the room opposite the chess and card room, and one person read a book in their own room. The last one took a leave of absence yesterday afternoon and went home. ”

I thought that judging from the current situation, the person who read the book and the person who went home were separate individuals, and there was no one to testify for them, so perhaps the inner ghost who guarded the self-theft was between these two people.

So I asked, "Where's the room for the reader?" ”

The old man said, "It's just across from my room." ”

I frowned and said, "Was he still reading in his room when you found out about the theft?" ”

The old man said, "Yes. ”

I asked, "Was his door closed or open?" ”

The old man thought for a moment and said, "I found that the safe was missing, so I ran to the aisle and shouted that I had met a thief, and he opened the door and came out." Well, it should be closed. ”

I nodded, thinking that if the door was closed, the reader would not be so suspicious. Because I know that the sound insulation effect of the cabin door of this kind of ship is relatively good, and it is understandable that he is reading intently and does not hear the movement of the theft.
