When I appeared in the information department, Gao Mingqiang told me, "We've checked the surveillance footage and no one visited last night. That auntie, Meng Yingqing, only went to Elder Liang's house at 9:30 this morning. We've investigated, and she usually starts work at this time, so there's nothing suspicious about that."
"In addition, we investigated the cleaning company and Meng Yingqing's background. We found out that she didn't know Elder Liang before," Xia Hou continued.
"Could it really be an accident?" I murmured. Just then, an officer came in and told me that Liang Youren had arrived.
We went to see the returned overseas student immediately. However, he seemed to look down on us. Even though he knew his father had passed away, his attitude remained sarcastic, showing no signs of grief.
At that moment, I couldn't help but scold him, "Liang Youren, what kind of attitude is this? Your father has passed away. His death is rather strange. If we find any clues, this might not end easily!"
"He's dead, so he's dead. I've been abroad for a long time and don't know his situation at all. Asking me is useless. I'm only back this time to cremate the old man's body, just to go through the motions!"
"You scoundrel!"
I've never met anyone like this. If I were Liang Youren's father, I would definitely be so angry that I'd come back from the dead and choke him, cursing, "You unfilial descendant! If I could, I'd stuff you back into your mother's womb and have you reborn!"
Of course, as police officers, we couldn't say such things. Just cursing him inwardly would suffice. Liang Youren quickly cooperated with us and signed the family consent for autopsy. Due to my previous profession, I had to participate in the autopsy; otherwise, I wouldn't feel at ease.
It's not that I doubted the skills of Zhang Keying, Xie Chuchu, and Ling Xiaotao, but rather that I wanted to examine the body myself.
Returning to my own stage, the other forensic pathologists were already dressed and waiting for me. I put on a sterile suit, a head cover, and rubber gloves. I began by performing a surface examination of Liang Zhongshu's body. We used instruments to check his fingernails, the bridge of his nose, philtrum, eyelids, and so on. However, his fingernails were clean, and there were no signs of struggle or ligature marks on other parts of his body. It was evident that Liang Zhongshu's body had only bruises from being hit by books. To find any hidden injuries, I even used the alkaline wash technique, but the result was the same.
At that moment, Liang Zhongshu had indeed not had any conflict with anyone. He might have knocked over a bookshelf and been killed by the books falling from above. After taking blood and urine samples, I used a Y-shaped incision to open the deceased's throat, then his chest and abdomen. After removing the ribs, I gradually dissected the deceased's organs, weighed them on an electronic scale, and observed their surface color. Following several tests, during the analysis of his blood platelets, Ling Xiaotao told me, "The deceased had a large amount of benzodiazepine compounds in his body. This indicates he had a habit of taking this medication long-term. Most people wouldn't take it for such an extended period, so I suspect Elder Liang might have had some psychological issues. Perhaps his recent activities can provide some clues."
"Benzodiazepines? Isn't that a component of tranquilizers? Elder Liang had to take tranquilizers?" I was a bit surprised at the time. Could his accidental fall and being hit by books be due to a psychological illness? He might have been hallucinating at the time.
When examining the deceased's stomach contents, I also saw residual traces of eggs and duck meat that he had eaten the previous night. Everything seemed normal. From the anal temperature, we accurately deduced the time of death.
I then turned the body over to examine his back of the head. The bruise here was indeed very obvious. Xie Chuchu used several books to conduct an experiment on the computer. It turned out to be a comparison with a famous book called "Resurrection." This book, with over 900 pages and a hardcover exterior, would have been enough to kill even a young person if it fell from a great height, let alone someone of Elder Liang's age.
He must have first been knocked down by other books, and then "Resurrection" coincidentally fell from behind and hit the back of his head. After several experiments, we gradually simulated the scene and some details of the incident.
Forensic technology has improved significantly. Our police can now use advanced technology to simulate the scene at any time based on the situation at the crime scene. Of course, all of this is done using geometric reconstruction of figures and objects. If an ordinary person saw it, they might think it was a Picasso painting. Only those who have worked in forensic investigation would understand what it truly represents.
I left the laboratory and arrived at my office when Xiao Yuande called to inform me, "We've investigated Liang Zhongshu's situation at the university. Elder Liang was a conscientious and good professor in the past, and he never had any scandals at school. Such a person should have no enemies."
"What about his son? Have you confirmed that he wasn't back at the time of the incident?"
"Yes, he's been in Britain all along. He emigrated five years ago and hasn't returned since. At the time of the incident, he was in a meeting with some experts. We contacted the police there to confirm."
"Have there been any unusual deposits into Liang Zhongshu's account recently?"
"I don't know about that yet. I'm preparing to return."
I found He Xin. She was already extremely busy, but when she saw me, she told me, "We've investigated some details. Elder Liang's income has always been stable. He also receives a high pension after retirement, and there are no abnormal sources of funds. Besides his son, he also has a sister and an older brother. His sister is also a forensic pathologist, and his older brother is a prosecutor. Liang's parents both passed away 15 years ago, reportedly from lung cancer."
"Send people to interview them. We can't miss any clue," I instructed. Xia Hou and some officers left. Gao Mingqiang is not very convenient at the moment, so I try not to assign him such tasks.
Liu Yuning was with Lu Chusheng. I didn't know what they were up to at first, but then I decided to go with them to visit Liang Zhongshu's medical college again.
This medical college was coincidentally the place where Zhang Keying had graduated. Since this case involved it, Zhang Keying naturally joined us on our trip to the medical college.
Upon arriving here again, quite a few people still remembered us. After all, we had solved a case here last time. After the previous Lolita case, Dean Gan seemed to have aged considerably. He was already old, and he would likely retire in a few years.
