Who was the murderer?
According to Wu Nan's previous deduction, many people had already thought of it. It was very likely that it was Gou Anhua, the younger brother of Gou Anguo! Otherwise, Wu Nan would not have mentioned Gou Anhua, but this required sufficient evidence to support it. Moreover, it was much more difficult to convict Gou Anhua than Gou Anguo because Gou Anhua had too little connection with the deceased.
The room was filled with buzzing discussions.
Wu Nan, who was deliberately silent for a moment, said,"You don't need to think about it. The suspect I've confirmed is Gou Anguo! It's not anyone else!"
"Song Qian and Qian 'an have alibis, and Qian' an's alibi is that he was on the plane from Xihang City to Jingdu City! Actually, when I found out about this, I was also very puzzled. Since Gou 'an was on the plane, it was impossible for him to commit the crime. Could it be that my deduction was wrong? I even tried to deduce the clues that I had given up until I saw this photo!”
Pa!
Wu Nan snapped his fingers!
The picture on the white screen changed. It was a photo!
It looked like a photo of a wedding scene. Three bridesmaids and three groomsmen surrounded the newlyweds!
"Look at this photo!" Wu Nan gestured to the people behind him." This photo came from Song Qian's Qzone. This is her wedding photo with Gou 'anguo four years ago. Note that the groomsman on the left of the groom, Gou' anguo, looks very similar!”
"This person is Gou Anguo's younger brother, Gou Anhua! The two of them are not twins, but biological brothers. They look very similar, but Gou Anhua is slightly taller, so I thought about it. On the day of the crime, was it really Gou Anguo who boarded the plane?”
"This is a premeditated and planned murder! If the murderer was really Gou 'an Guo, then he must have thought about how to get rid of suspicion after killing Song Dong. The simplest way was to have a sufficient alibi, and killing someone must not be known by too many people. Or rather, it must not be known by outsiders or people who could not be completely trusted!”
"Out of caution, the country of Qian 'an probably wouldn't find someone to perjure themselves, and there's a problem with the legal effect of relatives testifying. So is it really the country of Qian' an who boarded the plane? I think it might be Gou Anhua!"
" Although the airport security checks are very careful, it's impossible to make a completely accurate test on whether the identity card is used by the person. For example, the appearance of most women after makeup is very different from the appearance on their identity card. You can only see it with your naked eye.”
"I believe that the Gou 'an Kingdom allowed his younger brother, Gou Anhua, to pass through the airport security with his identity card and board the plane to the capital! This will be the evidence of Gou Anguo's alibi. I didn't go in this direction for no reason. Before this, I said that Song Qian had sent money to Gou Anhua four times, totaling 18 million. This is very unusual, unless Song Qian and her husband had a very strong interest in Gou Anguo. Divide the spoils after getting the inheritance?"
"Therefore, in the final supplementary investigation, Gou Anhua also became the focus of the investigation!”
"We investigated Gou Anhua's phone records, bank statements, and ID card usage for the past year. The day before Song Dong was killed, Gou Anhua's ID card had purchased a train ticket from Xihang City to Mo Hai City. The arrival time was 9 a.m. on December 13th last year, which was twelve hours before the death of the victim, Song Dong.”
"There's more! According to the information provided by the mobile company, the mobile phone signal of Gou 'an Country appeared in Mo Hai City on the day of the crime. This was a problem that ordinary people would not notice at all. However, many people had encountered mobile signal base stations with a certain coverage area. For example, the mobile phone signal of Hainan Province was covered by the mobile phone base station of Hainan. When a mobile phone owner with a Hainan number left Hainan and came to Guangdong, Usually, you would receive a message from the mobile company, Guangdong Mobile welcomes you!”
"Because the mobile phone number signal has left the coverage area of the Hainan signal base station, it was detected by the Guangdong signal base station and automatically sent a text message by the background system!”
"Same logic! The mobile phone signal of the Gou 'an Country belongs to Zhejiang, but it entered the directly governed city of Mo Hai, so he also received such a message. Mo Hai Mobile welcomes you. According to the information provided by the mobile company, it is enough to prove that on the day of the crime, the mobile phone signal of the Gou' an Country appeared in Mo Hai City."
"However, according to Gou 'an's statement, he should have been on the plane at that time. He had already flown to the capital. How could his phone not be on him? If it was on him, then he was lying! He wasn't on the plane at that time. He was in Demon Sea City! The person on the plane was his younger brother, Gou Anhua!”
Wu Nan suddenly spoke faster."According to the data provided by the mobile company, Gou Anhua's mobile phone number was detected in the capital after the incident. We also contacted the company and extracted the location information of Gou Anhua's QQ and WeChat. On the night of December 13th last year, Gou Anhua's ID card booked a hotel room in the capital. After the person with the Gou 'an ID card checked into the hotel, Gou Anhua's QQ and WeChat logged in from the 4G network. He switched to the Wi-Fi and logged in to the IP address of the public Wi-Fi of the hotel that he had used his Gou 'an Country ID card to book a room in!”
"In other words, according to the location of the mobile phone signal and the mobile phone software, we can confirm that on December 13th last year, the Chinese from Gou 'an was in Beijing, but his identity card was used in Shanghai. The identity card from Gou' an was used in Beijing, but according to the location of the mobile phone signal, he should be in Shanghai. It couldn't be that the two brothers 'phones were stolen at the same time, right? And they even happened to switch places and appear in Shanghai and Jingdou?”
"The only explanation is that they exchanged their identity cards!”
Wu Nan paused again and took a deep breath. He raised his hand and knocked on the blackboard."Most of you here are superintendents. I think everyone should understand what it means when a person voluntarily provides wrong information in a murder case and lies when questioned by a superintendent.!”
Pa!
Before Wu Nan could finish, he snapped his fingers again.
A new photo was projected on the white screen.
A shoe print from the crime scene!
"This is the only clue found at the crime scene that can point to the murderer. A size 43 hiking boot print!”Wu Nan quickly added," The Gou 'an Kingdom wears size 43 shoes!”
"In summary, Gou Anguo has sufficient motive to kill, as well as sufficient time to kill. Moreover, he lied when the superintendent questioned him! An alibi can be said to be invalid. Therefore, I think Gou Anguo is the murderer!”
"Arrest him!"
