Under Wang Chuanmin’s interrogation, Qin Xiaohui quickly buckled.

"I..."

Qin Xiaohui’s eyes were unfocused; she indeed went to that street at the time.

"I was just following... I didn’t do anything..."

Qin Xiaohui’s words were evasive.

Wang Chuanmin waved his hand: "Qin Xiaohui, I’m giving you an opportunity now, and I hope you can grasp it."

"The fact that we brought you here means we already have certain evidence."

Wang Chuanmin wasn’t lying about this.

Qin Xiaohui and Li Baowei are both being questioned, and their fingerprints have been collected. Lu Chuan is manually comparing the fingerprints and should have results soon.

On the other hand, when Wang Chuanmin arrived at the scene to arrest Li Baowei, he discovered something interesting.

In the courtyard of the renovation company where Li Baowei works, there was a truck parked.

At the crime scene, by the gate and the edges of the road foundation in the village, a trace of tire marks was found.

Initially, the Tianzhou City administrative team did not conduct extensive investigations on the tire marks.

However, after the major case team arrived, during Lu Chuan’s second on-site investigation, he identified what vehicle left those tire marks.

The traffic police team has been investigating the Changning thermal box truck produced ten years ago over the past two days, but without significant progress.

Coincidentally, there was such a box truck parked in the courtyard of the renovation company where Li Baowei worked.

In the other interrogation room, Li Baowei was being questioned by Wang Song.

"Li Baowei, tell me, how did you kill Wang Jingya, and why did you do it?"

Wang Song’s interrogation was direct and startled Li Baowei.

"Officer, could you be mistaken?"

"Wang Jingya and I are high school classmates, and I’ve been pursuing her all along. How could I possibly kill her?"

Li Baowei’s thoughts were clear, as he logically responded to Wang Song’s question: "Besides, the police questioned me before; when Jingya went missing, I was drinking with some friends and had never left."

Wang Song frowned.

The reason Li Baowei almost got removed from the suspect list during the police investigation was mainly due to his alibi.

However, alibis could be fabricated, yet what method did the other party use? President Wang hadn’t figured it out.

"Li Baowei, having you here means we have certain evidence. Now, we give you a chance to confess voluntarily. If you don’t cherish it, don’t blame us for being unkind."

Li Baowei shook his head: "Officer, I truly don’t know what you’re talking about. Jingya is the girl I’ve been chasing since high school, and all our classmates know how much I love her. How could I kill her?"

Meanwhile, while Lu Chuan was conducting fingerprint analysis, which was about to conclude, Qin Xiaohui was being interrogated.

About ten minutes later.

Unexpectedly to Qin Chuan.

The fingerprints found on the woodpile at the crime scene weren’t Li Baowei’s, but Qin Xiaohui’s.

In other words, the person who cooked the corpse wasn’t Li Baowei but Qin Xiaohui!

However, what was puzzling was that Qin Xiaohui’s blood type is AB, whereas the blood type found on the leaves of the plum tree was type O.

That means the blood on the plum tree wasn’t left by Qin Xiaohui.

However, Li Baowei’s blood type is type O.

"Could it be... a crime committed by two people?"

Concluding this, Lu Chuan felt a bit bewildered.

Based on the preliminary investigation results, the police didn’t assume multi-person involvement.

"Director Zhao, send this result to Captain Wang. In any case, there’s a breakthrough regarding Qin Xiaohui; these fingerprints are confirmed to be hers."

After finishing up here, Lu Chuan left the Criminal Investigation Team of Tianzhou City.

Earlier, when Wang Song led a team to arrest Li Baowei, a Changning box truck was seen parked in the courtyard of the renovation company where Li works.

Lu Chuan needed to go over to check the tire marks, confirming that the tire marks at the crime scene were indeed left by this truck.

Renovation company.

"This truck was originally a thermal truck, but the insulation equipment inside broke, so after we bought it, we removed all the equipment and used it for hauling."

The renovation company’s manager explained to Lu Chuan.

After circling the truck, Lu Chuan focused on the right front tire.

Without needing the photo of tire marks found on-site, Lu Chuan could determine with just a glance that this truck was indeed the one that had been to the crime scene.

"Has this truck been used recently?"

Lu Chuan asked.

The Boss shook his head: "I wouldn’t know, usually, Li Baowei and his team use this truck, but it seems to have been taken out recently."

"Could you open the cargo box?"

The Boss nodded: "Of course, no problem."

Looking back, he said to a young man behind him, "Chen, bring the keys."

The young man following the Boss shook his head: "Boss, the keys are with Li Baowei; I don’t have them."

"Li Baowei..."

Li Baowei had already been taken away by the police.

After pondering for a moment, the Boss said: "Forget the keys, just break the lock open."

The young man complied and went into the room to fetch a hammer.

The Boss handed Qin Chuan a cigarette on this side.

"Officer, could there really be something wrong with Li Baowei? The guy’s usually quite honest here, and he gives our company advice, designs, and does a lot of work."

Lu Chuan shook his head: "That’s still uncertain."

It’s indeed still uncertain whether Li Baowei is the murderer or one of the murderers.

The fragmented fingerprints have been matched to Qin Xiaohui, so she is definitely the perpetrator.

The remaining bloodstains on the plum tree are type O blood, which coincides with Li Baowei, and the box truck appeared on the site, indicating Li Baowei was at least present on site. But whether he committed the murder still depends on the outcome of subsequent interrogations.

Lu Chuan’s attention to this box truck is because he suspects the truck’s compartment is the primary crime scene.

From the current situation, Wang Jingya had not gone missing that day but encountered Qin Xiaohui driving by. She probably got into Qin Xiaohui’s car and left the neighborhood of Chen Yang.

The renovation company manager was chatty, inquiring about many details of the case from Lu Chuan, but Lu Chuan responded perfunctorily, also questioning some of Li Baowei’s matters at the company.

"The guy is easy-going, and we maintain good relations."

The Boss shared some of Li Baowei’s information: "Though he can be a bit headstrong, I heard he’s been pursuing a girl from high school... For years... Oh, seems like it’s the one who was killed..."

"Boss, the hammer’s here."

The Boss received the sledgehammer, crashed it on the cargo box’s lock twice.

"All set!"
