Superintendent Kagg arrived at the scene 20 minutes later. Kag opened the trunk and took out the test kit, and then took out a pair of gloves from his pocket. He led Jimmy into the room and listened to Jimmy explain the process again.
Kag first checked the doors and windows to see if there were any signs of lock picking, and then looked around to see if there were any footprints. It was clear that Jimmy went in, and no one entered the house after him, so the footprints were very important. The door was kicked open by Jimmy. There are 2 footprints on it, which match Jimmy's shoes, so there is no need to record them.
Kag found half of the shoe print at the door, only the sole part, and it was very light. It was obvious that the person who came had cleaned his shoes outside, leaving only a little dust. He placed a ruler next to it and took pictures. Circle it with a marker.
Karger continued to walk around the house to determine if there were exits elsewhere, if there were marks on the windows, and to determine if the suspect had entered and exited elsewhere.
Continuing to check inside from the front door, the few footprints found were left by Jimmy when he entered the house. No more footprints were found when he went inside.
Kag checked in the shoe cabinet in the foyer and found no similar sneakers. The footprints at the door were basically definitely not those of the deceased.
Kaag went upstairs and checked the wound on the head of the body and the bullet holes in the wall in the bedroom. He took out a tape measure to measure the width of the bullet holes, and then took pictures of them. After everything was processed, he took a pair of tweezers and Diandian took out the broken bullets from the wall and put them into the evidence bag.
"Jimmy, did you go out and see if Dr. Kevin is here?"
Jimmy walked out. Coroner Dr. Kevin Smith and his assistant were waiting at the door. Jimmy shook hands with Dr. Kevin and told him to go straight upstairs for a checkup.
Dr. Kevin performed a preliminary examination and then asked emergency personnel to come up and take the body down.
Kager asked Jimmy to raise his hand to simulate the position where the dead man was shot in the head. When it was in the same line as the bullet hole in the wall, Kager walked to the door, stretched out his hand to simulate a pistol and started to recreate the murder scene from the doorway.
This hand is obviously based on experience. According to normal ballistic calculations, the bullet holes need to be measured, and laser light or hand-pulled wires are used to locate the position of the gunman and the height of the gun.
Kag judged the position of the murderer and the height of the gun, and signaled Jimmy to put down his hand. He turned to face the door, took out a fingerprint developing reagent and sprayed it on the door handle. The fingerprints on it were very dense, and the interlaced fingerprints were very blurry, but there were still a few A relatively complete one, Kager collected the fingerprints and put them in the evidence bag.
After checking several rooms, they were relatively complete and had not been messed up, which further showed that this case was a deliberate murder.
Carg took Jimmy out of the house, looked around, and said to Jimmy, "Jimmy, go and ask around to see if the neighbors have heard any gunshots or noticed anyone unusual. By the way, Find out who has installed surveillance cameras nearby and check."
"Okay." Jimmy walked to the surrounding neighbors and asked door to door. A few households didn't knock on the door, but it didn't matter, because the people around him didn't hear the gunshots, and they didn't notice any unusual people nearby. Move around.
"Kage, the problem is a bit big. None of them heard the gunfire. There should be a silencer. If it was a normal gunshot, it is impossible that everyone did not hear it. In addition, there is no surveillance here, so it is difficult to obtain information. "
"Well, let's go back first, check the traffic camera video, and enter the fingerprints into the fingerprint database for comparison."
"It is unlikely that traffic cameras will locate the suspect. As far as I know, the surrounding intersections are small intersections and have not been installed."
Kag and Jimmy did not continue patrolling, but returned directly to the police station, scanned the extracted fingerprints into the computer, submitted them to the fingerprint database, and waited for the results.
The coroner's office called and the autopsy was completed. Karger went to get the autopsy report while Jimmy waited in front of the computer for a match.
The matching results came out. Jimmy took the printed results and looked at them. There was no matching result. A total of three fingerprints were collected, and none of them matched.
This fingerprint database is a criminal fingerprint database. Criminals who have been arrested will leave fingerprint backups. If there are no results in this fingerprint database, there is basically no way to determine their identity. We can only wait until they commit another crime and enter their fingerprints. The match is successful and the case is reversed.
Kag came back with the autopsy report and the warhead report from the laboratory on the way.
"Jimmy, the report is out. Please write a case report and submit it. The cause of death was a bullet to the head. The bullet was a 9mm Parabellum pistol. The model of the pistol is unknown.
The following are the presumed characteristics of the suspect. Based on the wounds and the single hole in the wall, it is basically determined that the murderer is about 180 centimeters tall. The shoe print should be some kind of sports shoe. It is impossible to infer the gender of the suspect. No one in the surrounding residents heard the gunshots. It is suspected that a silencer was used. Based on the sales volume of bullets and common pistols, it is speculated that it may be a Beretta 92F with a silencer. "
"Okay." Jimmy took the report and began to fill in the case report. Jimmy had always been lazy when it came to writing matters like this. He would write less if he could, streamline it if he could, and get it done quickly. But this time, it was a case involving death. , it’s troublesome. Once the on-site investigation, case evidence, autopsy report, warhead report, suspect characteristics, etc. are all done, don’t go on patrol today, you can get off work directly.
Jimmy finished the report. It was already dark. He put the report directly on Kag's table, went to change the equipment, finished it and went home.
Jimmy's police car has become a public use for the police station. Those who take over the night shift will choose one to drive this car to patrol, and also test whether the police lights are normal at night.
It seems that Kag and Jimmy did nothing. They simply recorded some contents and shelved the case. The key is that they do not have so much energy to focus on such unsolved cases. Every year in the United States, there are very, very many cases. There are many cases like this, and every police station has cases that have been left unsolved for several years, ten or even decades.
If this case is later considered to be related to other cases, it can be investigated together with other cases and the case will be continued at that time.
You may think that they are very childish, and they are not like the police who handle cases in movies and TV shows, but this is the reality. The overall homicide detection rate in the United States is just over 50%. In recent years, there have been about 16,000-20,000 homicides in the United States every year. There are too many cases like this in the United States that are shelved because there are no conditions to solve them. By the way, China's homicide detection rate has been above 99% in recent years. For this, you can see the data released by the Ministry of Public Security.
For the American police, if no one reports the crime, or if no body is found or other obviously special cases, it means that there is no homicide. At most, it can be regarded as an ordinary shooting case and a closing report will be completed.
