Chapter 24 third chapter

Now I know that it was Michelle, not Devon, who suggested the Virgin Islands vacation. The ambiguous relationship between Devon and Michelle will inevitably cause conflicts between Brandon and Devon.Devin, Kerry, Michelle and Brandon often had disputes.It's not just a conflict between Devon, Michelle and her husband Brandon, Carrey is also involved and plays a significant role. During the investigation, an eyewitness revealed to us that he had seen Devin at Michelle and Brandon's home the night Devin Gizman was murdered. The eyewitness was sleeping when he was suddenly awakened by an argument. He saw a girl standing on the doorstep with her back to him, and there were two other people in the room, and the three of them were arguing.The witness checked the time, and it was exactly twelve thirty-five.

I think this can verify when Devin left Kerry's house and where she went on the night of the crime.The witness saw Devon at 12:35, that is to say, Devon had a quarrel with Kerry at 9:30 that night, which was three years after she appeared at Michelle's house. Hours.During these three hours, Devin not only had a quarrel with Kerry, but also had a conflict with the Michelle couple, so there must be a connection between the two. According to my analysis, the person who has been playing a leading role in the dark has varied and sophisticated methods, making this conspiracy develop toward its depth.

Then we sprayed the Michels' room with fluorescamine, a substance similar to luminol that glows brightly when it comes in contact with red blood cells.It is a white or light yellow solid.It is a fluorescent derivatization reagent for amines, amino acids, peptides, proteins, alcohols and phenols. It is mainly used for liquid chromatography fluorescence detection and fluorescence spectrum analysis. However, we get nothing. If this is the first scene of the murder of Devin, there should be blood left.After careful inspection of the scene, we found nothing. At the same time, we will not forget that dirt and weeds were found on Devon's trousers. These things only exist in the open area, or in the garden grass, and the possibility of such things appearing in the bedroom is very small.

We decided to spray fluorescamine in the backyard of the Brandons' home, and found traces of blood on the manhole covers and pipe joints, which were no longer available for DNA testing.In violent cases such as homicide and injury, there may be bloodstains on the objects at the scene, the victim and the criminal.Generally speaking, the bloodstains are more obvious, which is not difficult to find, but sometimes you need to check carefully to find them.The color of fresh blood is bright red, and it gradually turns dark red or dark brown due to the change of hemoglobin after it flows out of the body. Old or warmed blood stains are taupe, while spoiled blood stains are light green or green.If the blood stain is attached to a dark object, its color is not obvious.Stains such as soy sauce, paint, fruit juice, pigment dyes, and rust can also be similar in color to blood stains, which should be distinguished.

It looked like the bloodstains had basically been washed away, and there was very little genetic material inside.Mature red blood cells do not have a nucleus.Erythrocytes, also known as red blood cells, are the most numerous blood cells in the blood, and are also the most important medium for transporting oxygen through the blood in vertebrates. We have to extract DNA from nucleated cells, like white blood cells, and there simply aren't enough white blood cells on site. However, we found another suspicious clue in the washing machine at the Brandon couple's home.There was a pair of Michelle's jeans soaked in the water in the washing machine. We took them out for testing and it turned out that they had been stained with blood.But since the blood has been diluted, if the water washes the blood off the trousers, it also dilutes the smell left by the killer, making it more difficult to track.

Therefore, it is difficult for us to extract complete DNA information now.In a pocket of Michelle's jeans, we found the plastic cap of a syringe, which was of the same model as the one found on Devon's waist: S14-Syringe.This is a plunger-to-needle syringe that uses a metal plunger that goes straight to the needle so that tiny samples can be aspirated precisely.The syringe is characterized by tight combination, strong and durable, and both the push rod and the needle can be replaced. Michelle Hertzel used to be an internist, so she had access to this size syringe. According to my analysis, a syringe was found on the waist of the deceased, and a plastic cap matching the syringe was found in Michelle's trouser pocket.How many accidental factors are there in this?Now we have to deduce the syringe and the circumstances under which it was separated.Obviously this is a man-made separation, so who will be the one doing the separation?There was no need for Devon to stick an empty syringe up his waist and die peacefully.She is not a psychopath, she is a normal person, and it is impossible for a normal person to commit such absurd behavior.Oh, and having said that, I also want to go into it in depth, and I don't want to hide my opinion, because it is part of my profession.

That syringe was artificially inserted.When the syringe is about to be inserted into a certain part of a person, the person should first pull off the cover on the syringe to expose the needle, and then insert it into a certain part of the other person.So, the moment the cap of that syringe is pulled off, what is the next coherent action as a doctor?Of course, Devin's body was not injected with the syringe before the transfer, but after Devon's body was transferred to the car. My analysis mainly describes the location of Devon’s body at that time and the size and distance of the space inside the car. Because it is not in the hospital but at the crime scene, the syringe cap that was pulled out in an instant cannot be missed in the car. The police searched it as evidence, and there was only one way to do it, which was to take the cover away from the scene as soon as possible. , and it happens to be the most convenient pocket when a person bends down to operate and insert a syringe.

I also found that the pocket where Michelle put the cap is on the left instead of the right, that is to say, Michelle pulled out the cap of the syringe with his left hand, and then put it in the pocket closest to his hand, which is the jeans Left pocket.
