Fifteen minutes later, Kevin came up again with an aluminum alloy telescopic ladder.

"Ask... Asked...... The priest said he didn't know what manholes there were... There are no keys ...... either."

As he spoke, Kevin pulled out a handful of steel shears from his back: "Only rely on this." ”

Wang Su said in a deep voice: "Come on, just clip the lock off!" ”

"Good!"

Setting up the ladder, Kevin easily cut off the small copper lock, and then gently pulled down the handle on the white iron cover.

"Squeak~~~~~~

The white tin cover has been pulled open by a crack!

Kevin nervously looked down at Wang Su.

Wang Su nodded: "Just pull it away, it's okay!" ”

"Good!"

But when the cover was fully opened, an object suddenly rolled off the back side of the cover, Kevin quickly dodged sideways, and with a "clang", the object fell to the ground.

The three of them looked at it and saw that it was an empty rusty can.

Caroline exclaimed in surprise, "Huh? Is it SPAM canned luncheon meat?? ”

Wang Su squatted down and picked up the empty can, held it in his hand and slowly turned it, the corners of his mouth slowly raised.

"Hmph, canned luncheon meat...... And the production date is still more than ten years ago......" said Wang Su, raising his head and staring coldly at the dark access hole.

Caroline seemed to realize something when she heard this, and looked up at the manhole sharply: "Someone stayed on it?" And also ate canned luncheon meat in the stuffy top floor?? ”

Wang Su was still staring at the pitch-black manhole, his eyes flashing with cold light: "If my intuition is not wrong, Kevin, you put your hand around the manhole and touch it......"

"Touch? Oh......! ”

Kevin stretched out his hand to grope in the manhole, and suddenly, his movements stopped, and he looked at Wang Su with round eyes.

"It's... This is... What? ”

I saw Kevin take out a large handful of ropes from the manhole, shake the rope open, and it turned out to be a rope ladder with two iron hooks!!

Caroline was shocked: "God, how can there be a rope ladder in there??" ”

"Hmph, did you guess right...... Wang Su's face was gloomy and terrifying, "He was very careful to hide the rope ladder for himself to enter and exit the top floor when he finally left here, and he also carefully reset the removed aluminum gusset ......"

"He??" Caroline gasped, "You're talking about... Murderer?? That's what he's hiding in here?? ”

"How many times do you want me to say? These are all speculations, even if the truth is right in front of you, it needs evidence to confirm it in the end......" Saying that, Wang Su took out a flashlight from his pocket and beckoned to Kevin, "Kevin, you come down." ”

Kevin nodded and climbed down the ladder.

"You wait!" Caroline grabbed Wang Su, who was about to go up the ladder, "I don't know what's up there...... You just rushed in? ”

"Even if there was anything alive for so many years, it would have died a long time ago!!"

Saying that, Wang Su bit the flashlight in his mouth and climbed up the ladder step by step, while Caroline and Kevin Huan held the foot of the ladder one left and one right, looking up and staring nervously at Wang Su's buttocks.

As soon as the "good guy ......" entered the top floor, Wang Su was shocked by the large amount of domestic garbage inside.

I saw a large number of mineral water bottles, compressed biscuit packaging bags and various canned bottles scattered around the small stuffy top floor, which almost made it impossible for people to settle down.

Wang Su half-bent over to the decorative dormer window of the dome and looked out through the glass.

"Sure enough, this is the perfect place to observe, and the scene in front and behind House 171 is in full view, if you have a telescope in your hand, hum... Clearly......"

"Work hard...... "Work hard," Wang Su muttered to himself, and began to pick up the garbage heap, "Let me see how professional you are...... Don't let me down, okay......"

As soon as he finished speaking, a black chemical industry full-body isolation suit was pulled out of the garbage heap by Wang Su, and Wang Su sniffed his nose.

"Hmm... There was a faint smell of blood...... "The flashlight light swam back and forth on this isolation suit, "The whole body isolation gown from head to toe... No wonder you can leave no biometrics on site...... Black... Well, it's a smart choice, black isn't so noticeable even if it's stained with blood, and it's not easy to attract attention on the way back from the crime scene in the night, so it's a good camouflage color......"

Wang Su continued to pick and pull through the garbage.

"Oh oh oh... Baby, you're here......"

A rusty dagger appears!

Wang Su became more and more excited, muttering to himself like a schizophrenic patient: "It seems... You're still very professional...... Leave all the crime equipment here in case you are questioned by the police when you leave the community, and make sure that you don't have evidence with you that could put you in a passive ......"

"Hey!!" At this time, Caroline's loud voice came from below, "Who are you talking to?" ”

"...... with the murderer," Wang said quietly.

"Don't scare me!!"

"Go back to the police car and bring two evidence bags, and a pair of gloves." Wang Su didn't dare to touch the dagger and protective suit rashly, he was afraid of damaging the evidence that might remain on these two items.

"Oh my God, another run?" Kevin grumbled, and then the sound of footsteps coming downstairs was heard again.

Thirty minutes later, Wang Su climbed down from the manhole with two evidence bags. The evidence bag contained, of course, the black isolation gown and dagger.

"Significant discovery?" Caroline looked at the bag in surprise.

Wang Su only nodded slightly, and then instructed Kevin to close the manhole, and then notified the trace experts of the Serious Crime Division to come over and finish it to see if there could be other valuable discoveries.

Then the three of them hurried down the bell tower.

As soon as he walked out of the church, Wang Su stopped his steps and turned his head to look around at the nearby surveillance cameras: "Now there is the biggest question, that is, how did the murderer not appear in the surveillance video on the way from the church to the victim's house, logically speaking, this is basically impossible to do, after all, there are not a few cameras along the way." ”

"yes," Kevin frowned and bowed slightly, "It's weird, unless he can be invisible, he can't hide from the surveillance cameras along the way." ”

"Stealth??"

Wang Su seemed to think of something, took out his mobile phone and called Hannah again.

"Hey Hannah, you can take a random screenshot of the surveillance video from the back door of the victim's house and send it to me, take a screenshot of all the angles that can be taken, and I'll see what the difference is from the current situation."

"Understood!"

"Let's go!" Wang Su waved his hand to Kevin and Caroline, "Go back to the backyard of House 171." ”

When the three of them walked into the overgrown backyard again, Wang Su's mobile phone received a screenshot from Hannah.

But as soon as he clicked on the screenshot, Wang Su was stunned.

"What's wrong?" Kevin and Caroline immediately stepped up.

"Look," Wang Su pointed to the phone screen, "it's really different from the status quo." Originally, there was a tall oak tree in the backyard, and the thick foliage blocked the back door......"

Caroline stared at the screenshot and nodded, "Yes, it did create a small blind spot at the back door entrance." ”

"But what's the point?" Kevin shrugged his shoulders, "Even if there is such a small blind spot, it doesn't explain why the murderer can't be found on the way from the church to here. ”

"Who knows......" Wang Su replied casually and began to search in the grass in the backyard.

Sure enough, a large stump of a rotten and blackened tree was quickly pulled out of the grass not far from the back door.

"Why did the good oak tree come to be cut down?" Wang Su circled around the stump with questions, "Judging from the screenshot, the branches and leaves of this oak tree used to spread out in a large range, extending all the way to the fence in the backyard. ”

Saying that, Wang quickly climbed over the half-man-high fence and came to the outside of the courtyard.

But as soon as his feet hit the ground, Wang Su seemed to feel that he had stepped on something in the grass outside the fence!

"Huh?"

Squatting down and turning over the grass to see, a round cast iron manhole cover appeared in front of you!!

"What did you find?" Kevin and Caroline walked briskly.

"Huh, manhole cover?" Wang Su stared at a few lines of text on the manhole cover, "Municipal flood discharge pipeline MPT-16 access port." ”

"I didn't expect it, I didn't expect it......," Kevin shook his head repeatedly, his face full of incredulity, "There is a flood pipe manhole hidden here!" ”

"Flood pipes?" Wang quickly raised the corners of his mouth and looked coldly in the direction of the church, "Miami is a city that is often hit by hurricanes and torrential rains, so there are flood pipes all over the city, otherwise it is very easy to waterlog!" Hmph, is this kind of flood pipe...... It's big enough to fit an adult! ”
