Sister Yu is a nurse at Renai Hospital, she is in her fifties, and her education level is not high, so she is still very satisfied with finding this job. At work, Sister Yu is very diligent and very popular with patients.
In the hospital lived a high paraplegic patient, Mrs. Gao. Three years ago, Mrs. Gao was paralyzed in a car accident and has been recuperating in Renai Hospital.
Mrs. Gao is kind-hearted and treats Sister Yu very well. reciprocated the favor, and Sister Yu was also very careful in taking care of Mrs. Gao.
It was unfortunate that Mrs. Gao was paralyzed in bed, but she was recently diagnosed with liver cancer.
Sister Yu was very sympathetic to Mrs. Gao, and she suddenly remembered the home remedies that had been passed down by word of mouth in her hometown, saying that it was very effective in treating cancer. She was grateful that Mrs. Gao had always been kind to her, so she boiled Chinese medicine according to the prescription and brought it to the hospital every day to feed Mrs. Gao to drink.
Mrs. Gao also had a strong desire to survive, and went to the doctor when she was sick, she drank Sister Yu's medicine, and did not tell her husband Gao Yanbo and her attending doctor.
Sister Yu is full of confidence, she believes that Mrs. Gao will definitely improve her condition after drinking her Chinese medicine. The seventh uncle in his hometown has already improved after drinking this medicine.
Mr. Gao brought Mrs. Gao a box of cakes from the violet cake shop, because of chemotherapy, Mrs. Gao was very weak and had no appetite, so he gave the cake to Sister Yu.
The cakes in the violet cake shop are very expensive, and Sister Yu is usually reluctant to buy them at all. She was very happy to receive this gift.
Sister Yu took the cake home and found that the box of the cake was wet. She put the cake box together with the bottle containing Chinese medicine for Mrs. Gao, and the liquid in the bottle came out and soaked the cake box.
She didn't pay attention to these details, took out the cake and enjoyed the deliciousness.
Unexpectedly, after eating the cake, she vomited and vented, passed out in a coma, and knew who was gone.
Her husband Xu Tian hurriedly sent Sister Yu to the hospital for rescue. By the time Sister Yu woke up, it was already a few days later. She learned from her husband Xu Tian that Mrs. Gao was dead, and she had been poisoned.
Sister Yu was very angry, Mrs. Gao is such a good person, why would anyone harm her?
At this time, Mrs. Gao's husband, Gao Yanbo, a senior chemist of the Forensic Department, came to see her. She earnestly begged Mr. Gao to catch Mrs. Gao's murderer.
But after learning that Mrs. Gao had drunk the Chinese medicine she boiled, Mr. Gao was furious and accused Sister Yu of killing Mrs. Gao.
Sister Yu was at a loss, she was kind and bought medicine for Mrs. Gao to drink, in order to cure her cancer, how did she become a murderer?
How did Sister Yu know that there was a cantharid in the Chinese medicine she gave Mrs. Gao to drink.
Cantharidin is a kind of beetle that can be used in medicine, but the cantharidin contained in its body is extremely toxic, and if the dose is not well controlled, it will be poisoned, causing acute heart failure. Even experienced TCM practitioners are very cautious when using cantharids.
Sister Yu didn't know that her ignorance not only killed Mrs. Gao, but also wasted a lot of police power, and almost caused Gao Yanbo to fall into prison.
Previously, the Chinese herbal juice soaked the cake box and seeped into the cake as well. Sister Yu ate the cake and was poisoned, so she fell into a coma.
Mrs. Gao's younger brother, Gu Zechen, learned that Sister Yu was unconscious after eating the cake given by her sister, so he hurriedly took the rest of the cake for testing and found that the cake contained cantharidin.
After investigation, the cakes in the cake shop were fine, only the cake eaten by Mrs. Gao was poisonous.
The cake was bought by Gao Yanbo, who once said that his wife had no hope of healing, and now she was in pain, and she was in pain even after drinking a sip of water after chemotherapy, and he wanted to help her get rid of it. Gu Zechen couldn't help but cast his suspicious eyes on his brother-in-law.
Fortunately, through the autopsy and forensic examination of the cause of death, Gao Yanbo's innocence was proven.
During this period, Lin Peipei, a classmate of Gao Yanbo and his wife, was also involved. Because Lin Peipei is Gao Yanbo's old lover, he is suspected of killing people because of love.
It also involved Gao Yanbo's father, Tongbo. In order to save his son, Tongbo took the blame for the murder on himself, and almost committed suicide by jumping off the building.
All of this was caused by Sister Yu's ignorance.
The confusing case is so simple, it is a bad thing that Sister Yu did with good intentions.
Sister Yu's killing of Mrs. Gao was an unintentional mistake, but it also violated the law. Gao Yanbo filed a lawsuit against her in accordance with the law.
Although he hated Sister Yu's ignorance for killing his wife, Gao Yanbo still thanked her for taking care of her wife with all her heart and intentions, and asked Liang Xiaorou to help her find legal aid and help her get rid of her crimes. He hoped that the tragedy caused by ignorance would not be repeated in the future.
In the end, Sister Yu was given a suspended sentence for manslaughter and did not have to go to jail. Learn from the pain, this bloody lesson, Sister Yu will definitely remember it for a lifetime.
