Superintendent Kag arrived at the scene 20 minutes later. Carg opened the trunk and took out the test bag, took out a pair of gloves from his pocket, and walked into the room with Jimmy to listen to Jimmy explain the process.

The first thing Kag checked was the doors and windows, whether there were any signs of lockpicking, and then observed whether there were footprints around, and it was already clear that Jimmy had gone in and no one had entered the house behind, so footprints were very important. The door was kicked open by Jimmy, and there were 2 footprints on it, matching Jimmy's shoes, so there was no need to record it.

Carg found half of the shoe prints at the door, only the soles of the feet, and very light, it was obvious that the person who came had already cleaned his shoes outside, leaving only a little dust, he placed a ruler next to him and took a picture, and then circled it around with a marker.

Kag continued to walk around the house to determine if there were exits elsewhere and if there were marks on the windows, in order to determine if the suspect had entered and left from elsewhere.

Continuing to check inside through the front door, several footprints were found by Jimmy when he entered the house, and no more footprints were found inside.

Kag checked in the shoe cabinet in the foyer and found no similar sneakers, and the footprints at the door were almost certain that they should not be the deceased.

Kag went upstairs, examined the wounds on the corpse's head and the bullet holes in the wall in the bedroom, took out a tape measure to measure the width of the bullet holes, and then took pictures of these, and when everything was done, he took a pair of tweezers and took out the broken bullets in the wall little by little and put them in the evidence bag.

"Jimmy, are you going out to see Dr. Kevin?"

Jimmy walked out, and the coroner, Dr. Kevin Smith, and his assistant were already waiting at the door. Jimmy shakes Dr. Kevin's hand and tells him to go upstairs for a check-up.

Dr. Kevin conducts an initial examination and then has first responders come up and bring the body down.

When Karg asks Jimmy to raise his hand, simulating the position of the deceased being shot in the head, in the same line as the bullet hole in the wall, Karg walks to the door and reaches out to simulate the pistol from the doorway to recreate the murder scene.

This hand is obviously experienced, and according to normal ballistic calculations, it is necessary to measure the bullet holes, and use laser rays or hand wires to locate the position of the gunner and the height of the gun.

Karg judged the position of the murderer and the height of the gun, signaling that Jimmy could put his hand down, he turned to the door, took out the fingerprint development reagent and sprayed it on the doorknob, the fingerprints on it were very dense, and the staggered fingerprints were very blurry, but there were still a few relatively intact, and Karg collected the fingerprints and put them in the evidence bag.

I looked at several rooms, and they were relatively intact and not turned over in a mess, which showed that this case was a deliberate murder.

Cag took Jimmy out of the house, looked around, and said to Jimmy, "Jimmy, you go around and ask around to see if the neighbors around you have heard any gunshots, if there are any unusual people, and by the way, ask who has installed surveillance cameras nearby, and check." ”

"Okay." Jimmy walked up to the neighbors and went door to door, and there were a few that didn't knock on the door, but it didn't matter, because none of the people around heard the gunshots, and they didn't notice the anomaly walking around.

"Kag, it's a bit of a big problem, none of them heard the gunshots, there should be a silencer, if it's a normal gunshot, it's impossible that everyone didn't hear it. In addition, there is no monitoring here, so it is difficult to obtain information. ”

"Well, let's go back first, investigate the traffic camera video, and compare the fingerprints into the fingerprint library."

"It is unlikely that the traffic cameras will locate the suspect, and what I know here is that several intersections around it are small intersections and are not installed."

Karg and Jimmy did not continue patrolling, but went straight back to the police station, scanned the extracted fingerprints to the computer, submitted them to the fingerprint database, and waited for the results.

The coroner's office calls, the autopsy is complete, and Karg goes to get the autopsy report himself, while Jimmy waits for the matching results in front of the computer.

The matching results came out, Jimmy got the printed results, looked at them, there were no matching results, a total of three fingerprints were collected, and none of them matched.

This fingerprint database is the criminal fingerprint database, and the criminals who have been arrested will leave a fingerprint backup, if this fingerprint database has no results, there is basically no way to determine the identity, and they can only wait for them to commit crimes again and enter their fingerprints, and then the match will be successful, so as to reverse the case.

Karg came back with the autopsy report, and along the way, he also got the report of the warhead in the laboratory.

"Jimmy, the report is out, you can write a case report and submit it. The cause of death was a bullet in the head, the bullet was a 9 mm Parabellum pistol bullet, and the pistol model is unknown.

The following are the speculative characteristics of the suspect, according to the wound and the single hole in the wall, it is basically determined that the murderer is about 180 cm tall, the shoe print should be some kind of sneaker, it is impossible to speculate the gender of the suspect, no one in the surrounding residents heard the gunshot, it is suspected that a silencer was used, and it is speculated that according to the number of bullets and common pistol sales, it is certain that it may be Beretta 92F plus silencer. ”

"Okay." Jimmy took the report and began to fill out the case report, this kind of text thing Jimmy has always been lazy before, write less if he can, streamline if he can, and get it done quickly, and this time, the case involving death, it will be troublesome, on-site investigation, case evidence, autopsy report, warhead report, suspect characteristics, etc., this bunch of things are done, don't go on patrol today, you can get off work directly.

Jimmy finished the report, and when it was dark, he put it on Karg's desk, went to change his equipment, and went home.

Jimmy's police car has become a public use of the police station, and the person who works at night will choose one to drive this car to patrol, and by the way, to test whether the police lights are working at night.

It seems that Karg and Jimmy didn't do anything, just simply recorded some content and shelved the case, the key is that they don't have so much energy on this kind of headless case, there are very, very many such cases in the United States every year, and every police station has cases that have not been solved for years, more than ten years, or even decades.

If the case is later considered to be related to other cases, it can be combined with other cases for investigation and continue to be handled at that time.

You may think that they are very child's play, and they are not at all as serious as the policemen in movies and TV series, but this is the reality, the overall homicide solving rate in the United States is more than 50%, and in recent years, about 16,000-20,000 homicides in the United States have fluctuated every year. By the way, the homicide detection rate in China has been above 99% in recent years, which can be seen by the data released by the Ministry of Public Security.

For the American police, if no one reports the crime, or no body is found, it is equivalent to no fatal case, and at most it is a general shooting case and a closing report.
