It rained heavily all night, and all the military spies, including Zuo Chong, stayed up all night, and everyone was guarding the ditches to protect the footprints they had just discovered.

In the middle of the night, the rain almost broke through the drainage channel and flowed into the ditches. Fortunately, the spies were discovered in time and cleared in the rain, so the only clues did not disappear.

After dawn, more technicians and equipment will be present and the footprint extraction work will be started.

The modern identification of footprints in the Republic of China began in 1932, when the Ministry of Justice established the Forensic Research Institute in Shanghai, which is the most authoritative forensic identification and forensic research institution in the State Government.

Based on the research results of the Forensic Research Institute, the Military Intelligence Department has long been proficient in the footprint inspection technology through actual combat.

The technicians first set up wooden piles on both sides of the ditches to prevent the collapse of the ditches wall from destroying physical evidence. Then, they used a diesel generator and tungsten wire lamp to completely illuminate the ditches.

The preparations were ready, and the two little spies slowly went down into the ditch, holding ropes, measuring rulers, and the camera began to take pictures and survey.

After preliminary investigation, a total of eleven pairs of footprints belonging to different personnel were found on the site, most of which were in poor preservation, and only three pairs of footprints were clearer.

"The footprint location was found, suspect A, footprint length was 27.3 cm, width was 10.4 cm, depth was 0.8 cm, stride was about 85 cm."

"Suspect B, footprint length 25.6 cm, width 9.2 cm, depth about 1.2 cm, stride 80 cm."

"Suspect C, footprint length 28.5 cm, width 11.0 cm, depth about 0.6 cm, stride 85 cm."

While investigating, the two small spies loudly informed the situation above the earth ditch, recorded the pens in the hands of the personnel quickly, and drew a schematic diagram at the same time.

After this step, the exploration work entered the next process. Professional environmental surveyors carried hygrometers and the thermometer jumped into the soil ditch, and conducted measurements around the on-site environmental factors.

Different environmental conditions will affect the morphology and recognizability of the footprint, so the temperature and soil moisture at the site must be analyzed to evaluate the age and deformation of footprint preservation.

After completing all the above work, after some calculations and comparisons, Song Minghao found Zuo Chong with the report and reported the results of the footprint identification.

"The sole of the suspect A has a bas-relief pattern, and the pattern is cross stripes, showing a distinct single pattern. The sole is worn relatively evenly, indicating that the shoe has been used for a period of time, but has not reached the extreme wear level."

"Based on the length of the foot, the other party's height is about 178-182 cm. Based on the footprint depth and foot width, the weight is 75-85 kg, the pace is relatively symmetrical, and the walking speed is normal."

Song Minghao read out the contents of the report, and Zuo Chong was a little surprised.

The weather station was bombed, and the Japanese benefited the most. From this idea, the murderer should be Japanese intelligence personnel.

But the suspect above is considered a stubborn man even in the West, and is even rare in Japan.

Let’s not talk about whether there are such strong men in the Japanese intelligence agencies. Even if there are, such people should not become secret operators, because they are too conspicuous and can easily be remembered by witnesses.

During Zuo Chong's thinking, Song Minghao continued to report on the situation of B and C, which was similar to A, and these two suspects were also much taller than ordinary people.

B is about 175-180 cm tall and weighs 70-80 kg.

C is 180-185 cm tall and weighs 85-95 kg.

After saying that, Song Minghao closed the report and asked for a question in his heart: "Second post, judging from the height and weight, the suspects seem to be very strong, so it should not be difficult to find witnesses, but why didn't we find it?"

Yes, why didn't you notice it? Zuo Chong nodded slightly, looked northeast, and suddenly turned around and asked after a while.

"Old Song, here is in the northeast of the weather station, right?"

"Yes, deputy post."

"That is to say, the weather station and Tugou are both southwest of the Jialing River, and the Tugou is located between the weather station and the Jialing River." Zuo Chong affirmed: "It seems that our previous speculation is correct. The suspect is indeed a weather station that was headed by water."

Song Minghao knew the meaning of Zuo Chong's words. Jialing River, Tugou and weather station were on the same line. This must be no coincidence. He roughly outlined the murderer's action route in his mind.

The murderer landed on the riverside, and hid all the way to the ditches. He waited until it was dark and approached the weather station. After completing the mission, he returned to board the ship and left.

After thinking about it, Song Minghao gave his own opinion: "Second post, let's look at the investigation from Chunyang now. It is impossible for so many strong men to be not paid attention to.

Even if the suspects eat and live on the boat, they always have to buy supplies or add fuel and coal. Moreover, the inspections on the river surface are so frequent, someone must have seen them."

This is true. No matter whether the suspect comes from another place or leaves from the mountain city to the meteorological station, as long as he takes a boat, he will definitely encounter inspections on the way. In terms of making money, the people of the National Government can definitely be regarded as conscientious.

Zuo Zhong pondered for a moment and shouted at the little spy: "Tell Director Wu the results of the footprint inspection and tell him that if no discovery is found, expand the scope of the investigation."

Mountain City, Ge Laohui Wenren Hall General Hall (verse 899).

Wu Chunyang and Sun Renyi, the Wenrentang, spoke indiscriminately. This person has worked with the Military Control Commission for many years and is considered to be the peripheral force of the Military Control Commission.

This time, Wu Chunyang contacted the other party, and it was better to use it to be mature than to use it. Moreover, Wen Rentang's strength is different from the past and has firmly ranked first in the Shancheng Ge Laohui.

There is the Military Control Commission above, the Police Department protects it, and there is huge financial support (replica yen). If this cannot emerge, the Military Control Commission will consider changing individual support.

Sun Renyi glanced at Wu Chunyang quietly and said: "Director Wu, I don't know what you are looking for to those people. If there is a case, I can find a few people to take the blame."

This chapter is not over, please click on the next page to continue reading! "Haha, what you think?"

Wu Chunyang put down the tea bowl in his hand and tilted his eyes: "Are you sure that your people will be punished by the case that our Military Commission is going to investigate?"

Upon hearing this, Sun Renyi smiled dryly and slapped himself a few times: "It's my fault. Don't worry, I have already spread all my hands, and there will be news soon."

It is a habit to be a dog. Sun Zhangqi, who was a little unruly in the past, had completely lost his other ideas after seeing the power of the Military Control Commission. Now he just wants to follow the Military Control Commission and have some soup.

At this time, a small spy walked to Wu Chunyang and said a few words, and sent a document. Wu Chunyang nodded and pushed the document to Sun Renyi and said.

"Old Sun, let your people focus on checking tall people. This is the specific identification standard, is there no problem?"

Sun Renyi took it and immediately patted his chest. The three of them were tall and strong, so it should not be difficult to find them.

But the slap in the face came. A day passed, Wenrentang's brother asked all the coast of the Jialing River and the ships, but still found no clues.

None of the members of the Gelao Club who relied on the Jialing River to make a living have ever seen suspicious people who meet the standards.

In addition, an investigation into government and military ships also ended in failure.

When we learned that the investigation was related to the sabotage case of the weather station, all the agencies involved cooperated with each other and would hand them over to the person regardless of who the case was involved.

The spies asked the relevant personnel, and the results showed that before and after the incident, except for foreign warships, the ships on the Jialing River had been inspected and the personnel had also registered.

There are indeed passengers or crew members who meet the identification conditions. The spies will immediately investigate, come to the door in person, or contact the ship's company.

After background review and verification of whereabouts of the crime, the suspicions of these people were eliminated one by one, and the investigation seemed to have reached a dead end.

After receiving a report from his subordinates, Wu Chunyang's expression was gloomy and sunny. The current situation was nothing more than two reasons.

Either their speculation was wrong, the murderer did not go to the weather station through the water, at least he did not go to the Jialing River.

Or the murderer was riding a foreign warship.

The first thing to do is to investigate is that the Jialing River is north of the mountain city area and the Yangtze River is south of the mountain. Since the Jialing River has not been found, let Wenrentang check the latter. Maybe the murderer set up a suspicion array and took the Yangtze River route.

The real trouble is the second one. Since the previous dynasty, many countries have stationed fleets along the coast and port cities of the Republic of China.

After the war between China and Japan began, some of the foreign ships that were docked on the coast and the middle and lower reaches of the Yangtze River returned to their homeland or colonies, and some followed the government to move westward to the mountain city.

As of this year, there are still several British and American gunboats that have not left the Republic of China.

Of course, these warships stayed in the mountain city not to protect the national government, but to protect the commercial and political interests of their respective countries. They rushed around the river, and the fishermen in the Republic of China suffered a lot.

When Japan attacked Pearl Harbor, Europe and the United States declared war on Japan, and the British and American warships that were staying in the mountain city were blocked in the upper reaches of the Yangtze River.

Even so, the other party was still eccentric. Not only did he forcibly ask for supplies from the government, but the sailors on the ship also harassed female students in the Republic of China many times, which aroused quite dissatisfaction among the people.

It would be better to expect these Wang Badan to cooperate with the Military Control Commission. Wu Chunyang thought about it and felt that it would be okay if he didn't check it.

The British Asian colonies were being attacked by the Japanese, and they needed support from the government on Asian affairs, and there was no reason to destroy the weather station.

It is even more impossible for Americans to be the weather station that Americans helped the government to build, and American experts died, so how could they make a mistake for themselves?

The source of the murderer is now unsure, and only one can be confirmed. The murderer may have bribed the British and American fleets of staying in Chongqing as a means of transportation to enter the scene.

Wu Chunyang's eyes flashed and he whispered to go and check the economic situation of the British and American sailors in Chongqing, especially the officers, focusing on whether they had large deposits in the bank or rented safes.

There are many foreign banks in Shancheng. These people will not be so stupid that they will keep the cash and gold bars they receive by their side. They will definitely be in the bank, otherwise it is equivalent to telling everyone that they have problems.

Once it is found that the British and American fleet officers have unknown income or store valuables in the safe, the case will be clear.

Wu Chunyang was convinced that if the British and Americans had secret deals with the murderer, they would make 100% preparations, such as remembering the characteristics of the murderer and selling this piece of information if necessary.
