He didn't dare to call the little girl Dr. Bai He for fear of exposing the little girl's identity.
Li Sen was a little surprised. Captain Li was more excited to see his sister than him!
"Doctor Bai, are you out to play today?" After he finished speaking, he noticed the big man standing next to Bai He and almost choked, "Mr. Si, you are also here..."
"Yeah." Si Yechen just nodded lightly without much expression.
"Yan Yan, how do you know that the deceased died about six months ago?" Li Sen asked curiously.
"If a corpse is soaked in water for more than three months, there will be a layer of white waxy substance on the surface of the corpse, referred to as corpse wax."
Ou Yan's eyes were calm and calm, and he continued, "It takes about half a year for an adult's corpse to form corpse wax. Adding in the weather, we can probably deduce the time."
However, estimating the time of death is far from enough, because what the police want to know is the person's height and age, so that they can compare it with the missing persons database and find clues.
"Yanyan, how tall do you think he is?" Li Sen came to his sister and asked.
"About 1.6 meters." Ou Yan looked at the corpse in front of him and analyzed, "After a person reaches adulthood, his height will decrease by 0.6 millimeters every year and 1.2 centimeters every 20 years. The height of adult men will decrease between the ages of 40 and 60.
Over time, their height will decrease by 2.3 centimeters, and by the time they are 60 to 69 years old, their height will be 4.9 centimeters shorter than when they were at their tallest."
Ou Yan visually inspected the long bones of the deceased, so he roughly concluded that the height of the deceased was about 1.6 meters.
The people around seemed to be watching a myth, looking at this gushing girl in disbelief.
As for the age of the deceased...
Ou Yan went forward, took a pair of gloves from Captain Li, put them on, and picked up a skull in front of everyone.
The onlookers were shocked. Who is this girl? She even dared to take the skull...
The key is that she takes it very seriously, like a knowledgeable person.
Li Sen also put on gloves and came to his sister's side, took the skull and observed, "Do you want to find clues from the lambdoid and sagittal sutures of the skull?"
"Hmm." Ou Yan looked at the skull and said, "I think the deceased should be around 35 to 40 years old."
At this time, everyone was stunned. Even Captain Li couldn't help but ask, "How can I tell?"
"You see, this place on the top of the skull is the sagittal suture. The healing of the sagittal suture starts at the age of 22 and ends at the age of 35. In addition, this place is the occipital bone. The gap between the occipital bone and the parietal bone is a bit like a human figure.
It is a herringbone suture, which started at the age of 26 and ended at the age of 47. Based on his third molar, it can be inferred that the deceased was between 35 and 40 years old."
Captain Li and his men did not expect to be able to obtain clues such as the deceased's age, height, etc. so quickly.
At this time, Li Sen also suggested, "You can extract DNA from the ribs of the deceased and compare it with the DNA of the missing person's family members. I believe it will be found out soon."
"Thank you, thank you so much, Expert Li and Dr. Bai!" Team Li didn't expect that the case would go so smoothly today. He was really lucky to go out today and met two big-shot figures at once.
Li Sen nodded and added, "In addition, there are no signs of struggle on his body or limbs. From this, we can infer that an acquaintance committed the crime. As for who it is, the phone soaked in water will give you the answer."
"Thank you so much, Expert Li, for reminding me."
This clue was particularly important to the police in handling the case. Captain Li thanked them both repeatedly, and then Ouyan and Li Sen took off their gloves, disinfected their hands, and left the scene first.
