When he returned to the Federal Building, Red was already waiting at the door of the conference room, and as soon as he saw Danny, he couldn't wait to put forward his needs.

"I need arrest records for gun violence and illegal possession of firearms in all of New York City's boroughs in the past six months, except for those where guns have already occurred."

Danny walked into the conference room with him, looking at the map of New York City's boroughs that had been painted beyond recognition, and looked puzzled, "I don't understand what you mean." ”

"Based on what you found at the scene, I don't think the suspect was going to commit the crime near the area where he lived."

Seeing Rhett's eloquent look, Danny was even more curious, "How did you do that with such certainty?" ”

"It's a kind of reverse profiling of geography." Emily helped explain.

"Although we don't have many clues at hand now, one thing can be confirmed, the murderer has a certain amount of planning, he committed the crime at the same time of day, and he made observations in advance to know the location of the cameras at the scene."

Rossi's notes contain a very detailed account of the interviews with the two men, especially some of the statements made by John Mohammed before he was executed by lethal injection.

"So?" Although Danny and Jack have teamed up to solve cases many times, it is the first time that they have truly experienced BU's seemingly whimsical way of solving cases that relies purely on empirical theory for deduction, and it is completely impossible to keep up with the train of thought.

"So in addition to the premeditated location of the crime, the murderer's choice of the victim was completely random? Or did these victims happen to be in the wrong place at the wrong time? Jiejie asked.

At noon the next day, Hodgner gathered everyone in the conference room, "The backgrounds of the five victims, an elderly man in his 60s, an ordinary office worker, a housewife, an insurance salesman, and a backpacker visiting New York have all been confirmed, and there is no intersection or commonality." ”

So the attack went to the next stage, a real terrorist attack.

Fortunately, this is not the first time Red has dealt with "Muggles", and he took the initiative to explain, "Demand-driven serial killers like 'Sam's Son' usually choose to attack in the area they are comfortable with.

"So away from his quarters, right?" Danny suddenly understood, and at the same time, he roughly understood the meaning of the circles drawn by Red on the map.

Paradoxically, in this purposeful attack, Muhammad's ex-wife's best friend, Mildred's niece, Nikia, became a substitute.

"Yes, but it also means that other areas of the city could be targeted." Emily muttered to herself.

The two modified the sedan and manually opened a shooting hole in the rear bumper of the car, through which one person was responsible for driving the car, and the other was lying on the back seat of the folded car, placing the XM-15 rifle on the spare tire in the trunk and firing at targets at three or four hundred meters.

Of the 27 victims, 17 were killed and 10 were seriously injured, including a 47-year-old F.B.I. intelligence analyst.

The serial murder case was dubbed the "Beltway Sniper Case" by the FBI, while the media referred to the killer as a "DC Sniper".

Therefore, in Rossi's notes, his motive for committing the crime is divided into two stages, the timeline of the early period is between February and September, and the motive or purpose of the crime is more confusing.

Red nodded, "At present, this is the case, of course, we do not rule out that like the 'DC Sniper', there is a premeditated victim who hides his motive by killing on a large scale." ”

Ironically, Mohammed's ex-wife was never shot, and his first target was his best friend, who had been encouraging his ex-wife to divorce.

And a serial killer with a plan and other purposes will intentionally or unconsciously make sure to do it outside his comfort zone. ”

Both are of African descent, and Rossi's notes detail their family background, with John Muhammad's original surname Williams but after 911 he changed his surname to Mohammed out of adoration for someone.

It is mentioned that in the early stages, Mohammed's real target was his ex-wife, in order to get the police to believe that her death was consistent with that of the victims who were randomly killed, so as to obtain custody of his three children.

After obtaining enough money through robbery and other means, Mohammed purchased a "Viper" XM-15 rifle with a holographic sight and a bipod and a blue Chevrolet Caprius sedan from 1990.

The victims of the "DC Sniper" are regardless of gender, age and color, and the attacks do not distinguish between day and night, which once again stirs up the hearts of the people who have just experienced 911.

This serial murder case is different from the others, and there are two murderers, 41-year-old John Mohammed and his child prostitution assistant, 17-year-old Lee Malvo.

Therefore, when we connect his crime locations with lines, his general range of activities is also basically framed, which is a profile of the geographical environment in the usual sense.

"Then let's pray that he just confined the crime to Manhattan Island, and if it was all New York, it would really be a needle in a haystack." Rosie sighed.

Between 2 and 24 October 2002, two men were arrested, and John Mohammed and Lee Marvo sniped 10 more and seriously injured three others, during which time two of the three were shot in the torso because of the massive cavity effect of the military rifle, which resulted in the removal of a large part of the internal organs.

(Pictured, it seems to have been drawn by an FBI expert after the fact.) ）

Because of the concealment of the modus operandi and the extremely long sniper distance (ordinary people can't pay attention to an ordinary car parked three or four hundred meters away), although the two acted extremely arrogantly, they still made the police and the FBI helpless.

It's "Sam's Son" and "DC Sniper", and everyone here either holds their chins or sticks up their heads, and they all seem to have a headache.

The F.B.I. quickly re-investigated the crime scene at the tavern, confirmed the consistency of the case through ballistic comparisons, and found Mohammed's fingerprints in a magazine, which successfully identified him and issued a warrant.

There were 14 victims during this period, 7 dead and 7 wounded, some of them out of vendetta, some for robbery, and some simply for the purpose of practicing marksmanship and guts, and Muhammad had his assistant Lee Marvo move.

If it weren't for the fact that Muhammad was so arrogant that he called the police and claimed that the police had missed a tavern robbery, the number of victims would have risen to hard.

The "DC sniper" mentioned by Rhett is a well-known name in the United States, and from February to October 2002, from Washington, D.C. to Virginia to Maryland, a series of sniper cases against innocent passers-by broke out.

This kind of random serial homicide is the last thing the police are willing to face, and it is also the case in which the BAU team can play the smallest role.

And when the clues are sufficient, and the profiling and behavior prediction are extremely accurate, behind it is the shocking number of cases and the bodies of the victims.
