The mentally ill dean was emotionally stable, and he introduced his relationship with Su Liutiao to the ace, and another point is that Su Liutiao's son Su Jiuwan pretended to be crazy and Su Liutiao arranged, and the specific situation was not clear to the psychiatric dean, and Su Liutiao did not make it clear at that time, according to Su Liutiao's death time, after his son pretended to be crazy, he died a week later, and the poisoning incident was only discovered by the psychiatric dean in recent days, and the psychiatric dean asked Su Jiuwan to continue to pretend to be crazy, the reason is that his father's whereabouts are unknown, what is the specific situation, Su Jiuwan knew, by chance, a neurological patient called Sanjiu to give Su Jiuwan's meal to the bag, maybe it was the wrong one, Sanjiu fell to the ground after a few bites, foaming at the mouth, the psychiatric director had a little medical knowledge, naturally understood that there was a problem in the meal, he immediately pulled a dog to do the experiment, did not expect that the dog was finished eating, but also died.

The psychiatric dean knew at that time that someone was going to kill Su Jiuwan, and the psychiatric dean asked Su Jiuwan to bring a dog with him, and he gave the dog what he wanted to eat first, the corpse of the three nines, and the psychiatric dean lied that he fell to his death, so he sent his body to the funeral home.

These things happened in the past few days, and the psychiatric director was afraid that the ace would kill Su Jiuwan when he went to the psychiatric hospital, but he saw Jin Shan go to ask Su Jiuwan the day, he was wearing a police uniform at the time, and he also appeared that day, so he didn't pay much attention to this detail.

With this news, Zhou Ling followed the matchmaker to the funeral home to check the body of Sanjiu, Zhou Ling quickly dissected the body, took the food in the stomach of the deceased to check, and a few hours later identified the deceased as poisoned and died, and the poison in it was methyl parathion.

Jin Shan is called Niu, because the mentally ill dean said that the deceased is called Sanjiu, since he has untied the note left by Su Jiuwan.

Li Sansan Jinshan is calculated by multiplication.

The nine of three and three, and the four and five of Li are calculated by addition.

Chung Yeung Festival is the 9th of September, and there are also 9 here.

The answer is that Three Nine was killed by a man named Red Spider.

Zhou Ling shouted. "Arrest someone, what are you waiting for?"

Ace analyzed. "It's useless to know now, in this way, let's lure the snake out of the hole and let Su Jiuwan ......... So that we can catch the murderer. ”

Jin Shan said. "The help of the psychiatric director is needed here."

The trio went according to plan.

The next morning, they received a call from the psychiatric hospital, saying that someone inside was dead and they were going to take a look.

Zhou Ling, Ace, Jin Shan, 004, 005, 018, these three numbered people followed them.

The deceased was Su Jiuwan, and there was a dead dog next to him, and Su Jiuwan foamed at the mouth.

Lying on the dinner table, several people carried the body to a room, and the dead dog was also carried away, Zhou Ling checked the body in the small house, dissected the body, and soon the results came out.

The deceased died of poisoning, and the poison was methyl parathion, Jinshan Ace blocked the scene, called the people in the kitchen out, checked, Zhou Ling checked the breakfast of others, only Su Jiuwan's breakfast was poisonous.

There were four men in the kitchen, and Ace watched them closely.

Man Number One said. "Comrade policeman, I didn't kill anyone, I didn't put the poison."

The second man, the third man, and the fourth man were all wronged, and they didn't do anything in the meal.

Jin Shan took them in for the purpose of looking for poison, but they didn't find that Ace and Jin Shan were looking for poison bottles everywhere in the mental hospital, or something to bring the poison in, they were there

The bottle used for methyl parathion was found in the trash can, and there was a little potion in it, but Jinshan found fingerprints on the bottle, and it is also a miracle that fingerprints can be found on the bottle, and there will be a paper pattern of instructions in the middle of the bottle, maybe when the murderer was poisoned, he was also hot, causing the bottle on his hand to be soaked with sweat, and the fingerprints were also burned on it.

The garbage in the garbage bin was turned out by them, and now of course they want to put them back, and a cleaner came to help, but this person paid the attention of the ace, because he had a red spider tattoo on his neck, although it was a little small, he must have seen it at such a close distance, which also told the ace that the red spider that Su Jiuwan said was him.

Ace Jin Shan immediately called this person to ask, and at first he didn't ask anything, but Zhou Ling got the fingerprint identification results on the bottle, and it was really the cleaner's.

The cleaner was recruited.

The cleaner is 56 years old, because he has a son who is not angry at home, often gambles outside, and loses a lot of money, which is not important, more importantly, his son loses his own sister to others, that is, the cleaner's daughter, and the creditor is called Su Batiao, Su Batiao wants to pull his daughter to be his junior, the cleaner is not willing to die, but his son signed a deed of sale with his net worth, what to do, this sue to the court can stop him, but Su Batiao released a sentence, if he does not pay the money, If he didn't pay back the money, he chopped up his son,

Since his daughter wants to be a junior for his brother, the cleaner does not agree, he pays his own money to help his son repay the money, and never let his daughter pass, and he will definitely be harmed if he falls into the hands of this kind of person.

Su Batiao agreed to his conditions, as long as he repaid the money within ten days, it was easy to say, Su Batiao decided that he couldn't pay back the money, ten days later, his daughter naturally sent it to the door, but after a few days, the cleaner had no way to prepare so much money, and wanted to tell his daughter to run away, since Su Batiao came to a sentence, the money didn't have to be returned, and he discussed it at the cleaner's house that day, as long as the cleaner helped kill a person, the money didn't have to be returned, and the whole chat process was how to kill Su Jiuwan, although the cleaner didn't agree, he still took the poison of methyl parathion, Su Hachijo gave him a few bottles and left.

The cleaner's daughter is really Bingxue smart, since she secretly recorded this video at home, but she didn't expect her father to really do something stupid.

The cleaner has been cleaning in the psychiatric hospital all the time, and this is an opportunity for him, because Su Jiuwan is also here, and he has specially poisoned Su Jiuwan's meals several times, because each of the people in the psychiatric hospital has prepared a lunch box with a name on it, which can also be said to be a coincidence,

The cleaner thought that Su Batiao killed a neurotic person, nothing more than to hide from his family's money, he was still a little unable to do it, once when he put medicine in the lunch box, since Su Jiuwan saw it, Su Jiuwan's dog ran in, and he also followed in, although he didn't see what the cleaner did, and he didn't care, thinking that he was stealing food, and the cleaner also thought that he was a neurological patient and definitely didn't know that he was drugged, so he covered the lunch box and left the canteen.
