"Team Ling, in the call records of the mobile phone card under Lu Qingyuan's name, there are only incoming numbers in the past three months, and no outgoing numbers. The investigation found that all the incoming numbers were advertising harassing calls, and Lu Qingyuan never answered them. ”

Although through Xun Jianguo's previous investigation, it felt that Lu Qingyuan should not have many people to deal with, but Song Jin's investigation of his call records still surprised Ling Zhan.

"He hasn't called anyone in three months?"

"Unless he still has a calling card that is not in his name. Song Jin also said with a look of disbelief: "In addition to the dozen or so incoming harassing calls, there are only SMS notifications that are regularly received every month to remind you to pay water and electricity bills." ”

Just as Ling Zhan wanted to ask Song Jin about the investigation of Lu Qingyuan's bank account, he heard Song Jin continue: "By the way, I counted the amount of Lu Qingyuan's monthly electricity and water bills, you can see Team Ling." ”

Song Jin walked to Ling Zhan's desk as he spoke, pointed to a few of the numbers and said, "This is Lu Qingyuan's electricity and water bill last month, which is obviously a lot higher than in previous months. ”

"The temperature is high in September this year, so there will be more water and electricity ....... Before the word "normal" could be spoken, Ling Zhan discovered the problem. Because instead of "some" more, the number he saw was almost double that of the previous months. Besides, autumn has entered in September, and the temperature is obviously lower than in August, why is Lu Qingyuan's water and electricity bill in September more than twice that in August?

"And, Team Ling. This is the total amount of electricity used in the water meter and electricity meter shown in the corridor of Lu Qingyuan's unit. Song Jin pointed to the two handwritten numbers next to him and said: "The results obtained after subtracting the total amount recorded on the water and electricity bill in September show that after entering October, in less than half a month, Lu Qingyuan's electricity consumption has been close to the total amount in September, and even the sum of July and August." ”

"It's not normal, it's definitely not normal. ”

"Team Ling, I asked Lu Qingyuan's next-door neighbor about this. ”

"How?"

"The neighbor said that because the sound insulation of the house is very poor, the sound of the faucet next door can be heard very clearly. According to the reaction of the female neighbor in her forties, she did find that Lu Qingyuan's room had a splash of water from time to time, as if he was at home and turned on the faucet. ”

"Let's go to the scene again. ”

On the way, Song Jin reported to Ling Zhan on the investigation of the bank account in Lu Qingyuan's name.

Lu Qingyuan only has a bank passbook in his name, which was handled by the unit for him and used by the labor department to pay his retirement salary. ”

"Are there any signs of a lot of money coming in and out?"

"Nope. Except for the pension of 3,447 yuan paid regularly every month, that is, the winter and summer seasons, heating expenses and heatstroke prevention subsidies, and there is no other input. ”

"How much money is in total?"

"That's also very strange. The withdrawal record of Lu Qingyuan's passbook printed out from the bank counter shows that he has not withdrawn a penny for five years. The total balance exceeded $220,000. ”

Because Lu Qingyuan has a household appliance repair shop under his name, as a single person, although no one knows the specific monthly income of the repair shop, it should be enough for Lu Qingyuan, who usually lives a frugal life. It's just that, doesn't Lu Qingyuan have any other expenses besides daily expenses?

Besides, since he has no relatives and no reason, why should he be so frugal, and what is the use of saving so much money?

With these many questions, Ling Zhan and Song Jin came to Lu Qingyuan's residence again. The two focused on the kitchen and toilet to carefully search, wondering what caused Lu Qingyuan to use more than twice as much water and electricity in the past month or so.

There are many household appliances in the kitchen, such as rice cookers, electric pressure cookers, electric woks, electric kettles, etc., almost all of them are available. However, it can be seen that they should all be second-hand goods that have been replaced by others and repaired by Lu Qingyuan.

Although there is also natural gas, the number displayed on the natural gas meter on the wall is less than 50 cubic meters, which means that Lu Qingyuan basically does not use natural gas for cooking. However, this is not the reason for the sudden and substantial increase in his electricity consumption, and the gas consumption of less than 50 square meters is enough to show that Lu Qingyuan has always preferred electricity to natural gas.

After the two who couldn't find the reason in the kitchen came to the toilet, they quickly found the clue.

Flush toilets, glass-partitioned shower cabins, men's toiletries, vanity mirrors, and a small storage shelf next to them are all in order. And it's so clean that it's obvious that it's the result of scrubbing every day.

This was completely different from the feeling that other places in the entire room left for Ling Zhan and Song Jin. It seems that this bathroom is not used by an old man in his sixties, but more like a young man who likes to be clean and clean.

"Team Ling, look. ”

When Song Jin picked up a brand-new blue bath flower from the small back basket in the shower room with glass partition, Ling Zhan's eyes suddenly lit up. Because Ling Zhan knew too well that such a bath flower that was specially used to wipe the shower gel, he never used it in his usual baths. It is only used when a woman is bathing, or when bathing a child.

"Could it be that in the last few days, there has been a woman who loves cleanliness living in this room?"

Ling Zhan and Song Jin can't help but have such suspicions, and only in this way can they explain the strange phenomenon of Lu Qingyuan's recent sharp increase in water and electricity bills.

Women love cleanliness and bathing, so they naturally use more water. In addition, after mid to late September, although the temperature during the day is high, the temperature in the morning and evening is still quite low. Therefore, people who take a bath at home, especially those with weak constitution, generally start to use the bath bomb on the top of the bathroom to keep warm.

At the same time, if there is one more person in the room, the amount of electricity needed for cooking or drinking water will naturally increase exponentially.

However, according to Xun Jianguo's investigation, Lu Qingyuan never dealt with other people, let alone took in any women at home. More importantly, the barefoot bloody footprints left on the inside of the bedroom door were clearly man's footprints.

Could it be that Lu Qingyuan's sexual orientation is really problematic, he secretly took him in at home, and the person who killed him in the end was not a woman, but a man in his forties?

Thinking of this, Ling Zhan and Song Jin knocked on the door of their neighbor's house again.

"Excuse me, have you noticed that Lu Qingyuan has taken someone in at home recently?"

"No way. The female neighbor in her forties flatly denied: "No way." Not to mention who to take in, even if an outsider asks him for something, he won't let you in. ”

"Don't even your neighbors let you in?"

"We all know Lao Lu's fetishes, so we never ask to go to his house. When something really happened, the most I could do was to stand at the door and talk to him. ”

"Is it possible that Lu Qingyuan secretly hid people at home without being discovered by you?"

"Don't ....... The female neighbor suddenly stopped at this point, thought for a moment before then continued: "If you deliberately hide a person, and usually pay great attention, although the sound insulation of the house is very poor, maybe you can really do it without being discovered by us." ”

Having said that, but from the face of this female neighbor, Ling Zhan and Song Jin could still see that she obviously did not believe in such a possibility in her heart.

"Let's go, you send this bath flower back to the technical department first, and let them check it to see if they can extract biological samples from it. I went to the nearby store to see which store sold it, and if anyone had an impression of Lu Qingyuan. ”

"Team Ling, you should go back to the bureau, and I'll take a look on the street. ”

"It's fine. ”
