190 BLOODY WEDDING PART 5

"Wait, to kill a person with air embolism you need a sufficient quantity of air; around 100 ml to kill an adult. The syringes we usually come across are only 2-5 ml. How did the killer pull it off?" Xue Lin was confused.

Inspector Han helplessly answered, "The forensic doctor said that the lethal dose for humans was considered theoretically between 3 and 5 ml per kg. And, as you said that 300-500 ml of gas introduced at a rate of 100 ml per second would prove fatal."

"I also said that the amount of arterial gas embolism that causes symptoms depends on location — 2 ml of air in the cerebral circulation can be fatal, while 0.5 ml of air into a coronary artery can cause cardiac arrest," a man said from the doorway.

He was a tall and handsome man. His brown eyes were reflecting in the light. He was wearing a lab coat, white shirt and black pants. Just by looking at him Xue Lin could tell that he was the forensic doctor.

He stepped closer and looked at Xue Lin. She could smell the odor of blood and medicine coming from his body.

He opened his mouth and said, "Little knowledge is a dangerous thing, miss."

"You are right. Thank you for the information," Xue Lin was always open about someone pointing at her mistakes. She thought of it as her blessing. "So, you are saying that it's possible to kill with a syringe."

"Quickly and painlessly. It takes seconds to kill a person without getting any reaction," he confirmed.

"Why didn't you tell me before? Did you know that you wasted our precious time?" Inspector Han chided him.

The doctor scratched his head. "I thought I told you. Maybe I was talking to myself so frequently that I had a feeling I told you."

Inspector Han sighed loudly. He introduced him to Xue Lin, "He is Dr. Yuren. As you can see, this guy is a genius in many aspects but he is an air-head when it comes to communicating with people."

"And Yuren," he introduced her to Dr. Yuren, "This is Xue Lin. She is the victims' relative."

"Just relative? I thought you two were close since you were closing the door," Dr. Yuren stated.

"I know her for three years. What are you here for?" Inspector Han didn't want to disclose any information about her and so he changed the subject.

"I came to give you the reports of the dead bodies. I wanted to wait but I thought you might want to see the reports as soon as possible." Dr. Yuren handed the reports to the inspector.

Inspector Han took the papers and unpinned the papers. He looked at them one by one and frowned deeply. "They died at the same time… how?"

Inspector Han explained, "It could be but when we searched for shoe prints, aside from you, your husband, cousins and uncles, there was only one pair of shoe prints around the victims. Those shoe prints were of a man. The size is 44."

Xue Lin pondered, "That means that the man is tall. I thought that the killer was a woman since the killing process was indirect."

"What gave you the idea that indirect killing can only be done by women?" Dr. Yuren asked her. He was observing her for a while.

Xue Lin narrated, "My theory is the killer cleverly used sleeping pills so that she didn't have to struggle while killing them. She couldn't fight two men anyway. That's why she put sleeping pills on the water jar and then killed the victims."

"Simple way of thinking, like beginners," Dr. Yuren commented. It wasn't clear whether he was satisfied or dissatisfied with the theory.

Inspector Han's expression didn't look good. He stated, "Hmm, I didn't tell you that from the pressure of the print we can say that the suspect's weight is 116 Ibs."

"How can a man with long legs have 116 Ibs body weight?" Xue Lin was surprised.

"Unless it is a woman in a man's shoe or a small man was wearing a large man's shoes to distract the police," Dr. Yuren remarked.

Xue Lin tapped on the table. "That's too clever. I already like the killer for thinking so deeply. It doesn't sound like a normal killer. But the question remains. How did he or she kill two people who were in two different places at the same time?"

"We have to go there again and investigate. Do you want to come along?" Inspector Han stood up and asked Xue Lin.

"Sure," Xue Lin agreed.

"I'll go back and check if I find anything else," Dr. Yuren said.

Inspector Han took his car and drove away. While driving he commented, "Your appetite got better."

It came out of the blue. Xue Lin was sitting beside him and pondering something else. Since she didn't completely hear what he said, she asked, "Pardon?"

"You better eat a lot more than the last time I saw you eat," he stated.

The last time, he recalled that no matter how delicious a meal was, Xue Lin didn't touch them and she couldn't stand the smell of the food. For a month she didn't touch any food. She only drank water and the doctor had to give her saline and vitamins to keep her alive.

Xue Lin chuckled dryly. "Hah, my husband said that I didn't eat properly today. So, he made sure that I eat two people's meals at lunch."

"I'm glad there is someone who takes good care of you. Your parents are useless." Inspector Han frowned as he recalled how she was treated by her family members after the rescue team found her.

Xue Lin couldn't agree more. "So they are. I'm glad that I didn't meet them in the main house. They didn't come."

Inspector Han inquired, "What about your nightmares? Can you sleep at night? I remember that you couldn't sleep a wink because of nightmares."
