About half an hour passed, and Yuna Hayasaka's phone rang. When she heard what the other party said, a surprised expression appeared on her face.

Ritsu Sasashima noticed her unconcealed expression and knew what the answer was, and Yuya Kumaki, who was a medical professor by profession, was indeed a major suspect.

"Police Department, I have found out what you asked me to investigate..."

"Well, he has a record of buying carbon monoxide, right?"

"Y-How do you know?"

Seeing Yuna Hayasaka's wide-eyed and shocked appearance, she even subconsciously covered her mobile phone, feeling that she had eavesdropped on her call.

Ritsu Sasashima said helplessly: "If you want to not be seen through what you are thinking, learn how to control your expression." ”

"Are you the same as the police department?"

“……”

Ritsu Sasashima knew that Hayasaka was implying that he was expressionless and paralyzed, it wasn't that he was expressionless, he was just a little tired from making expressions, and he didn't like to show his emotions.

"By the way, there is one more thing you definitely didn't guess!"

"What's the matter?"

Yuna Hayasaka showed a small expression and boldly hooked her index finger towards Sasashima.

Obviously older than himself, but very naïve. Ritsu Sasashima had no choice but to lean down and bring her face to her, and asked patiently, "Can you say it now?" ”

The handsome face at close range made Hayasaka subconsciously want to retreat, but found that she leaned back and caused her body to lean against the car door, she quickly blinked her big eyes to suppress her accelerated heartbeat, and whispered, "Actually, there are witnesses who saw Mr. Yuya put carbon monoxide into the yoga ball, and there are more than one." ”

Ritsu Sasashima still maintained this posture and lowered his head in contemplation, and the thumb of his left hand subconsciously turned the ring on his index finger.

Witnesses can apply for search warrants and detention warrants, and punching multiple yoga balls is supposed to be an experiment to calculate the time it takes for carbon monoxide to fill a car and kill people.

After all, he worked in the hospital during the crime, and he had an alibi.

"It's very... Well? ”

Ritsu Sasashima noticed that Yuna Hayasaka had her little head down, her whole face was flushed, and her hands were still tightly crossed together, what was wrong?

"Do you have a sudden illness?"

"You're sick!"

“？”

Yuna Hayasaka shifted a little to the side to escape someone's charisma, fanning her cheek with her hand and asking, "Is there anything else you need my help with?" ”

"Nope."

Ritsu Sasashima walked towards the black Toyota Lexus, and Yuya Kumahui, who was sitting in the main driver, still looked depressed, not because his acting skills were good, he really didn't want to kill his son.

Politely knocked on the car window twice, and when Yuya pushed the car door, Ritsu Sasashima asked indifferently, "Have you bought carbon monoxide recently?" ”

“！”

A hint of unnaturalness flashed on Yuya Xionghui's face, but he quickly concealed it, and he calmed down and said, "Yes, you know my profession, I have been experimenting with carbon monoxide recently. ”

"Actually, my major is quite compatible with your work, and I want to know what medical experiments still need to inject carbon monoxide into multiple yoga balls."

"What you're talking about, I don't understand."

Seeing his hard-mouthed appearance, Ritsu Sasashima was not in a hurry, he leaned on the car door with his hands in front of his chest, looked condescendingly at Yuya who was sitting in the car, and said slowly: "The hospital has already witnessed the carbon monoxide you bought half a month ago being injected into multiple yoga balls, are you still ready to deny it?" ”

"I... Yes, I poured carbon monoxide into a yoga ball, but I did want to experiment. Yuya Xionghui said with a smile, "I want to study how to save animals with damaged or poisoned respiratory systems, and carbon monoxide is needed, right?" ”

It's pretty watertight.

But judging from Yuya's expression and words, this person is extremely conceited, thinking that he is amazing, a little arrogant to the point of pride.

"You should need a lot of animals that are about to be humanely exterminated to experiment on you, right?"

"yes, how... Do you want to provide it to me? ”

Ritsu Sasashima raised his hand and pointed at the vehicle that was still in the cordon, and said in a casual tone, "Don't you like human experiments?" Doesn't it seem like a good thing to arrange animals? ”

"You... What do you mean? ”

"It's sad that my only son is dead."

“……”

Noticing the anger in Yuya Kuma's eyes, Sasashima felt that he was only one step away from success, and after standing up and pacing back and forth a few times, he asked, "I didn't expect that my carefully planned plan would cost Yuya Gonori his life, right?" ”

"As a doctor, you know how painful carbon monoxide poisoning can be, right? Symptoms such as chest tightness, tinnitus, and weakness in the limbs begin with dizziness, headaches, and vomiting at first. ”

"Oh yes."

Ritsu Sasashima smiled and looked at the towel on the co-pilot, which was still stained with brown liquid, and said, "You should have felt it when you hugged your son just now, right?" Incontinence, he was really in pain before he died. ”

“…… That's enough. ”

Yugu Xionghui clenched his fists tightly, gritted his teeth and said, "What about the evidence? If you can't produce evidence, don't mention this in front of me, be careful that I sue you! ”

I have heard a lot of threatening words since I was a child, and I am tired of hearing them.

Ritsu Sasashima waved to Hayasaka, who was on standby, pointed to the rear tire of the car, and said, "You go and see if there is a foreign object in the rear tire?" ”

"Okay."

Yuna Hayakasaka squatted down to carefully check the rear tire of the car, and suddenly found that there was a white object stuck in the rubber gap of the tire, and when she pulled it out with a tool, she found that it was an air lock.

"Police Department!!"

Ritsu Sasashima pinched the gas plug he got from Yuna and said indifferently, "Are you familiar with this thing?" ”

Yuya Kumaki's face turned pale the moment he saw the gas block, and he panicked out of the car and rushed towards Sasashima, trying to take away the crucial evidence.

Ritsu Sasashima, who was already good at melee combat, could not give him a chance, and after pulling up the distance, he raised his foot and kicked him in the abdomen, and the back of Yuya Kumaki's head slammed on the car door and almost fainted, and his body fell to the ground on his stomach.

"I noticed you just now, and you've been groping for something since you came to the scene... When I learned that the air plug of the yoga ball was gone, I had a bold guess. ”

Ritsu Sasashima squatted down and put the air plug in his hand in the evidence bag in front of Yuya, then handed it to Yuna and said, "I wonder if you're looking for that gas plug too... You are deliberately given time to stay at the scene of the crime, just so that the police can secretly come here to investigate. ”

"It's a pity that you forgot to check your tires, otherwise it would be really difficult to handcuff you."

“…… It's all the woman's fault. ”

"Huh?"

"If it weren't for the fact that the woman suddenly wanted to take Gangnori to camp in Mt. Takao, Gangnori wouldn't have died!!"

Yes...

At the end of the day, he only cared about his son.

Ritsu Sasashima didn't bother to talk nonsense with him, so he directly took out the handcuffs and took him away, glanced at the car that was still parked on the side of the road, and remembered the identity and background of the deceased that the police had investigated at that time.

Will you regret giving up overseas doctoral studies for the sake of your husband and children?

I regret falling in love with such a man who ignores you and kills you for the sake of your affair partner.

"Woo..."

“？”

Ritsu Sasashima looked sideways suspiciously, and found that Yuna Hayasaka beside him had already stopped crying, his head was full of question marks, and he didn't know if he made her cry or what...

I don't seem to be able to keep up with this subordinate who thinks extremely fast.

"What are you crying about?"

"I'm sorry for Miss Masako, she was originally raised in an orphanage, and no one shed a tear for her until she died."

"Isn't there?"

Yuna Hayasaka raised her head suspiciously, and saw Sasashima looking at her with the corners of her mouth slightly raised, her beautiful eyes reflecting her pretty face with pear blossoms and rain, and it was rare to feel the presence of temperature in his sight.

"Didn't you cry for her? That's enough. ”

What a gentle smile.

That's how he laughs...

What, it's such a nasty thing to suddenly say such heart-warming things.

Sometimes invisible sultry is not the deadliest, self-attacking... It's the worst thing.

Ritsu Sasashima raised his hand and looked at the time displayed on his watch, the first case took more than half an hour from the time it was taken to the time it was solved, not counting the rush of more than half an hour, and the total time was two hours and twenty-nine minutes.

It's pretty fast.

"Gone."

"Where are you going?"

"When you get off work, you naturally go home."

“…… Oh. ”
