Chapter 741 There is more than one murderer
A few blurry videos confirmed that the bullets came from the same pistol and the ballistic test results. These are the few clues that everyone has at present. Soon, the conference room It fell into silence, instead of the brainstorming that you said and I said in the past.
This feeling is actually very uncomfortable, waiting for the murderer to continue committing crimes, waiting for new bodies to appear, waiting for the murderer to make a mistake or actively contact the police, just like the "Son of Sam" case and the "DC Sniper" case.
David Berkowitz, the murderer of "Son of Sam", took the initiative to write letters to the police and the media. John Muhammad in the "DC Sniper" case not only called the police the man who eventually led to his arrest phone number, and also left letters and a tarot card at the crime scene.
They use this method to attract public attention, and use it to ridicule and humiliate the police. After succeeding again and again, these serial killers begin to regard such killings as a competition with the police, or Talk about a game of cat and mouse.
Now everyone in the BAU, including Danny, Joyner and Jack, are all being humiliated. This humiliation not only comes from the murderer's arrogant crime style, but also from the existing victims and the foreseeable ones. Future victim guilt.
Because now they have no means to stop the other party from doing whatever they want.
Jack was sitting in the corner, playing those videos on the tablet over and over again. These video files were processed by Garcia. Compared with the previous ones, the frame drops were more obvious, and they were almost catching up with cartoons. The original video is much smoother and the clarity has also increased a lot.
Unfortunately, these images do not show the murderer’s face and cannot be used for facial recognition. Garcia is still busy at the moment. She is retrieving videos from other time periods through the NYPD surveillance system. , hoping to find some clues from the onlookers at the scene after the incident.
This is what psychologists and criminal investigation experts learned from the "Son of Sam" case. After committing the crime, the murderer often cannot help but return to the scene of the crime.
Using facial recognition to quickly and accurately identify onlookers one by one, the FBI has a bunch of ready-made programs that can be applied, but it just requires some manual assistance.
The problem is that if there are only a few dozen people, it will only take a little time, but all five crime scenes are in public places. No matter how indifferent New Yorkers are, when they see a body surrounded by security tape, they will There are not a few people who stop and watch.
The identification of nearly one or two thousand faces at all crime scenes cannot be done by Garcia alone in a short time. Even if all the analysts and technicians in the operations center are added, it will take a long time. For a long time.
But as the old saying goes, as long as the mind does not slip, there are always more solutions than difficulties. Rossi told Garcia, just find a way to confirm that the same face does not appear around more than two crime scenes. .
After spending the whole night modifying the facial recognition program to run automatically on the computer, Garcia fell asleep on the table. In her words, as long as the computer does not issue an alarm, it means that there is no harvest, so everyone Don't wake her.
Jack had no intention of competing with the computer program. He repeatedly viewed the videos of the crime just because he had a vague feeling, but he could never find the moment of inspiration.
Soon Emily and newcomer Luke Elwes joined in, followed by Danny and Hannah, then Aubrey and Joyner, and finally, except for the one still standing in front of the map Rhett was thinking hard, and everyone else stood behind Jack.
"Does anyone see anything strange?" Feeling that the oxygen around him was almost being consumed by these guys, Jack had to ask.
“No.” Everyone shook their heads, including Hotchner, who was holding his arms and having a straight face.
Except for the first scene where there was no video of the crime, Jack played the videos of the remaining four cases one by one in the order of the crime.
"I do have a strange feeling, but I can't explain why." Aubrey rubbed his chin and said nonsense, which attracted unanimous eye rolls from everyone. "The murderer's pattern after shooting was different. We don't know what happened the first time, but the second time the murderer obviously didn't panic, but calmly pretended to be a passerby and left quickly.
But the third and fourth times, he trotted away from the scene again, giving the impression that he was a little flustered. However, when he committed the fifth crime at noon yesterday, he returned to the way he left calmly before. This does not make sense. "
In the end, Emily said the key. Generally speaking, serial killers commit crimes, which is a process of gradually becoming more proficient. From the first time they are unfamiliar and panicked, and full of mistakes, they gradually become cold-blooded and turn murder into murder. For something as casual as eating and drinking.
As Rossi said next, "After committing the crime five times, it stands to reason that his behavioral pattern should have been fixed long ago."
"What do you mean? The murderer is not the same person?" Just as Jack had judged before, Kate Joyner was not a vase, and he immediately understood what everyone meant.
I don’t know when Rhett also stood on tiptoe behind everyone, "I know there is a way to verify this, but it may need to wake up Garcia."
"Hand in Give it to me." Jack separated from the crowd and walked out of the office. He took a deep breath to regain oxygen before opening the tea room door.
A few minutes later, the microwave in the pantry made a "ding" sound, and then an alluring aroma of passion fruit mixed with the aroma of rum instantly wafted throughout the corridor.
Everyone in the conference room followed the large piece of cake in Jack's hand and watched eagerly as he opened the door to the office next door.
Not long after, Garcia's surprise cheers and an exaggerated bang came from next door.
Jiejie and Hannah exchanged dumbfounded looks. Within a few minutes, Jack came back with a blue lip mark on his face.
“Well, Garcia used a digital coordinate model to analyze the heights of the murderers in the crime videos. The one who calmly left was six feet one inch (about 185 cm) tall, while the one who ran away in a panic was the tallest. Only five feet and 10 inches (less than 176 centimeters)."
"So there is indeed more than one suspect." Hotchner still had a straight face and his frown even deepened.
"So, there is more than one suspect, what does this mean?" Teacher Rossi's small class can finally start.
"Most serial killers who partner up will not commit crimes separately unless there is a reason to do so. For example, Mohammed and Malvo in 'DC Sniper', although they committed crimes separately for the first time, Malvo Ervo's hand, but Mohamed was sitting in the car not far away
There was also Kenneth Bianchi and his cousin Angelo Buono, Bianchi was in the last two. He was arrested for leaving a lot of clues when he committed a crime alone, but that was because Buono had escaped due to a mental breakdown before. "
Reed partnered with another famous serial murderer this time. For example, Kenneth Bianchi and Angelo Buono are one of the disgrace of the LAPD, known as the "Mountainside Strangler".
Between October 1977 and February 1978, 10 young women were murdered in Los Angeles. They were aged between 12 and 28, and they were all sexually assaulted before being strangled to death. The naked body was dumped on a hillside near Hollywood, covered with scars of abuse.
