Chapter 244: The Corpse Examination, the Remains of the Death Scene
The kitchen of Jonny Dennison's house is very large, with enough space for three or four people to work at the same time, and it is about 40 square meters.
Refrigerators, ovens, roasters...
Arguably.
This kitchen can make the food and drinks needed for the daily body.
Jonny Dennison's body was lying face down and back on the side of the refrigerator, with obvious heavy blow wounds on the back of his head, blood stains left on the ground, and the collar of the deceased was stained blood-red.
Not far in front of the deceased, there was also a square object covered with a black cloth.
On top of the black cloth, there is also a pink and white bewitching carnation.
Dean's eyes narrowed slightly.
Carnation, also known as caryophyllus, is the most common flower species used in the United States to mourn the deceased.
Black cloth, carnations...
These things, left behind by the murderer?
Dean didn't rush to check what it was, and after observing the kitchen environment first, he crouched down in front of the deceased's body and looked at it carefully.
According to the side face of the deceased.
Dean is sure that this is Jonny Dennison himself, because Daisy's book has a picture of the other party.
Jonny Dennison is about 1.84 meters tall, wearing a casual home suit, with a slightly fat body, a big belly, and an upward-facing side face with a look of consternation, as if he was unexpectedly attacked before his consciousness died.
Dean squeezed the other man's arm.
The touch is stiff, but the joints can still move, but compared with normal people, it is like a mechanical joint rusty card, and there is a lot of sluggishness.
When a person dies, the blood and body fluids stop flowing, so the joints and muscles will begin to stiffen, and when the water in the body of the body begins to lose, the blood and body fluids will penetrate each other, and the body will become soft again.
This change process is generally 70 hours:
Within half an hour to two hours of death, muscles and joints begin to stiffen.
After about 9 to 12 hours, the body will be completely stiff.
It was not until thirty hours after death that the body ended its stiffness and began to soften.
Of course, this refers to the change in the case of room temperature.
If the ambient temperature is higher than 35 degrees, the 70-hour process of stiffening and softening will be reduced to 24 hours.
At present, the noon temperature in Los Angeles is about 18~26 degrees.
There is no air conditioning in the room.
So Dean can basically be sure that the time of Jonny Dennison's death will be before eleven o'clock this morning.
He touched Jonny Dennison's armpit again.
After death, the body begins to stop producing heat, and the heat in the body also begins to lose outward until it is at the same temperature as the outside world.
The process.
The rate of temperature loss is faster on the surface of the body than on the internal organs.
Normal forensic tests are generally to measure liver temperature, which Holz has done before.
Dean did not bring equipment and could only measure the temperature of the deceased's body.
The armpit is the part with the smallest error.
Jonny Dennison's armpits are messy and smelly, and there is something that makes people feel sick.
Fortunately, the feedback was good.
Dean could vaguely feel the residual temperature of the other party's body through the light gloves.
This shows that the time of Jonny Dennison's death should not be more than five or six hours, otherwise there will be no tactile feedback that is significantly higher than the ambient temperature.
It's past 1:30 p.m.
That's the case.
Based on the previous mortem.
Dean can surmise that Jonny Dennison died between 8 o'clock ~ 11 o'clock in the morning.
But this time is still not accurate enough.
Dean continued to carefully hold the deceased's forearm, lifting it up slightly, and then looked at the deceased's forearm, the skin towards the ground.
It's looking at corpse spots!
Corpse spots, in fact, are the death of the corpse, the blood loses its power and is deposited in the lower parts of the vascular network, resulting in the capillaries and venules in those lower parts are filled with blood, and the dark red and dark purple scars appear through the surface of the skin.
This process usually takes two hours after death to appear, and the scar becomes more pronounced over time.
And it usually appears first in the area facing the ground.
On Jonny Dennison's forearm, some lumpy corpse spots can already be seen, not dark or light.
Considering the size of the other party's fat.
Dean didn't make any inferences, lowered his forearm, and instead pulled away Jonny Dennison's eyelids.
After death, the transparency of the cornea decreases, until it is completely impossible to see through the child's hole, and it is grayish-white, and this change process also has obvious rules:
Small white patches appear on the cornea 5-6 hours after death.
Cloudy flakes for 10-12 hours.
15-24 hours, cloud-like, the child hole can still be seen through.
For more than 48 hours, the child's hole cannot be seen through, and it completely becomes dead and white.
Under Jonny Dennison's eyelids, you can see that the transparency of the cornea is significantly reduced, and the pores have spread, but the whole has not become completely cloudy, but there are some small white spots on the inside of the cornea.
From this it can be concluded.
Jonny Dennison was dead for at least five or six hours.
It's early noon.
Combined with previous cadaveric symptoms.
Dean guessed that Jonny Dennison died at 7~8 o'clock in the morning.
this time.
A lot of people get up.
The nanny, Teresa, under normal circumstances, will also start preparing the family's breakfast around this time.
But the other party's reporting time was probably close to twelve o'clock.
Where was the other party before?
There are also the wife and son of the deceased Jonny Dennison, even if they skip breakfast for such a long time, isn't it strange that their husbands and fathers are gone?
...
Dean put these doubts to heart for a moment and began to check on Jonny Dennison's injury.
Checked.
The obvious scar on Jonny Dennison's body surface is a dented blow wound located on the back of his head.
The blood from the wound crusted and coagulated, but based on the outline, experienced Dean, it was certain that the murder weapon was some kind of curved blunt weapon, something like a baseball bat.
The wound is clean, and it can be determined that it is a one-hit kill, and there are no follow-up additional hits.
The murderer should have carried out a sneak attack when Jonny Dennison turned his back on him, and Jonny Denison had no defense against the murderer.
The wound is convex and concave.
According to the force analysis.
This shows that even if the murderer holds the murder weapon and hits the center of gravity of Jonny Dennison's wound, it is lower than the position of Jonny Dennison's wound.
This shows that the murderer's height is definitely not high, and the murder weapon is not very long.
In Dean's mind, he couldn't help but think of the Barbie-like face of nanny Theresa again.
Although there is no height to see Teresa standing up.
But who is he?
Just a glance.
Teressa's measurements, waist proportions, and approximate height, Dean is basically clear.
Teresa looked at the long legs and slender waist, but the height was only about 1.6 meters, if he took a short stick like a rolling pin and raised his hand to smash it, it was very consistent with the force analysis of the wound on the back of the head of the deceased Jonny Dennison.

Key Teresa is the babysitter of this home.
Even if she held the murder weapon and stood behind the deceased Jonny Dennison, the deceased would not suspect it, and would only show a look of surprise and shock on his face when he was about to die.
Dean is suspicious of the babysitter Theresa, and there's one more important point!
The wound of the deceased, located in the back of the head.
The back of the human head is actually a very vulnerable part.
It is made up of bones, nerves, and skin tissue, and encloses the pons and cerebellum, and can range from coma or neurological injury to vegetative or brain death.
Therefore, there are often elderly people, taking a bath, going to the toilet, standing unsteadily, the back of the head rattles against the wall, and the person is paralyzed and dies.
Although Jonny Dennison is a man who is more than 1.8 meters tall and at least 200 pounds, if he is hit in the back of the head with a blunt object by a woman, he can easily cause his current injuries.
This is also the only part where the opponent can kill Jonny Dennison so easily.
At present, the nanny Teresa is very suspicious.
...
"This eucalyptus looks so relaxed."
Dean whistled.
Whether Teresa is the murderer or not also needs to determine whether she has the time and motive to kill.
People are on the scene, and they can't run away.
These are not in a hurry.
The previous survey, which seemed tedious, actually took Dean less than two minutes.
He set his gaze on the cube in front of the deceased, covered in black cloth.
This thing, in fact, appeared very abruptly.
Leaving certain items at the scene of a murder is the favorite thing for some arrogant serial killers to do.
They use these things as a symbol of their own status, in order to distinguish them from other homicide elements, and to show their own distinctive and unique taste for killing.
This kind of person is arrogant in his heart.
Nanny Teresha, doesn't look like that.
So...
What is under this black cloth?
