We use math every day and numbers can be applied to almost anything to predict events, outcomes or even someone’s actions based on probability. Math can even help locate criminals and be an important part in criminal investigations. Criminal geographic profiling is a way to locate a hot zone of where a serial killer may potential live based on locations of crimes. Image enhancement and reconstruction is a way of enhancing a photograph enough to be able to recognize significant markings to help identify a criminal. Photos are also a source of faces and using math, facial recognition software has been developed to find a face in a database in just a few seconds. Math is often used for DNA profiling and fingerprinting matching for evidence found at a crime scene. Using math to help find criminals is an interesting concept, but most cases use math and has helped with cases in the courtroom.
In an attempt to evade authorities serial killers will attack in a seemingly random pattern. Although without realizing it all of their crimes are likely an equal distance away from one point,...
From a trial strategy point of view, you always start with the piece(s) of evidence you believe are most damaging to the client's case and work backwards looking for an exploitable flaw in the search and seizure procedure that would make that or those item(s) inadmissible. The further back in the series of events you can argue a fatal flaw, the more likely that the evidence and any additional materials which flowed from that particular item of evidence will be excluded. This is the practical analysis of all the times we see or hear of law enforcement arguing that there was some technical item which drew their attention and suspicion and justifies their hunch that criminal activity is afoot.
The FBI uses Statistics to solve hundreds of cases, statistics allow the FBI to make predictions to solve a case before they have evidence enough to solve it. Since the FBI is the United States largest law enforcement agency focused mainly on United States soil the FBI needs a way to stay organized so the FBI built a computer program called ViCAP. ViCAP is a database to hold all of the FBI’s crimes. This program can be used to find a similar case in years passed and look back to see what kind of person the statistics point to. The FBI uses advanced statistics compiled by using the mean (average), and looking at the type of person who committed the crime, the severity of the crime, and the age of the person who committed the crime. While out in the field, FBI agents take notes on even the smallest thing that could give a hint to solving a case such as if the crime scene is organized denotes multiple offenses. Statistics are also compiled when looking for a stolen item such as money from a bank, for example, if money is stolen; statistics might tell you where to look, the age, gender, ethnicity, and type of person (down to the car they might drive). Statistics are especially important wh...
Serial killers are typically known to fantasize as to how they intend to kill their victims. Additionally, they develop a well laid out plan as to how this will occur and in doing so leave little evidence at the scene for investigators to follow up with. Serial killers also tend to target persons that may not be missed for some time such as prostitutes or run-aways. As a result a long period of time will pass before the victim is ever found and an investigation is started. This becomes an ongoing challenge to
The stereotype that exists for individuals who commit serial murder is one that mainly includes males of a specific race. However, it is now known that white males are not the only individuals who commit serial murder. Men and women from all racial and ethnic backgrounds and socio-economic statuses have been found to be serial murderers. Although this information has been presented to society, the cultural schema of the white male serial killer is still prevalent. The assumptions that involve serial murderers often include two aspects, the serial murderer is male and the serial murder is a type of “lust murder”, often involving sexual crimes by a sadist (Keeney and Heide, 1995). Keeney and Heide (1994) define serial murder to be the premeditated murder of three or more victims committed over time, in separate incidents, in a civilian context, with the murder being chosen by the offender.
Serial killing is rampant in the U.S. According to estimates in a recent study conducted by the FBI, there have been about 400 serial killers in the U.S. in the last century, with the total number of murder victims ranging from 2,525 to 3,860 . Various experts in the field have suggested that there may be anywhere from 50 to as many as 300 serial killers active at the same time, although there is no clear evidence supporting this . Certainly, an estimate of 300 active serial killers seems at odds with the FBI’s estimate of 400 over the entire previous century. But an estimated 80% of the serial killers in the past century have emerged since 1950. For whatever reason, serial killing is clearly on the rise, with the term itself coined only since the mid-1970’s, so perhaps 300 active serial killers at one time could be unfortunately possible. The number of serial killing in the U.S. is staggering.
In the last three decades the USA has been troubled by an approaching problem, the serial killer. A serial killer is a person who kills a number of people, usually considered over five, with a cooling off period between each murder, usually one murder at one given time). Two murders at one time occasionally happen and these murders may go on for a period of months or years until the killer is caught. Throughout the last three decades the US serial killer rate has risen 94% and it is estimated that by the next millennium it will claim an average of 11 lives a day. Serial Murder is an epidemic; there are at least 35 serial killers active in the USA today who claim one third of the annual murder rate. The USA has 6% of the world's population yet it has three quarters of all serial killers. Not only are serial killers appearing in more numbers in the US but also all over the world countries are terrorized by serial killers, which are appearing in more numbers year and year after. KILLER TRAIT: A serial killer is a typical white male, 20-30, and most of them are usually in the USA. Their main motives are sex (even though the act of sex may or may not take place), power, manipulation, domination and control. The sex motive is usually rape for an organized killer and sadism for a disorganized killer. They act in a series of 5 or more murders with a cooling off period between each murder.
Serial killers commonly attack a single target at a time one on one. There also tends to be no or very little relation between the person being killed and the killer (murder 1). “The nature of this drive has been heavily debated, but there is a consensus on some points (Anderson 1).” Many researchers have noted sexual behavior in the murder.
Organized killers often appear to many as socially normal. They typically plan their kills in advance, have some way of transportation, and carry a ‘murder kit’ with them which contains various tools necessary for their crimes. They also often cruise public spaces for victims which includes prostitutes, the homeless, teenagers, students walking on campuses, or active night spots such as bars and clubs. Additionally, their victims tend to fit a specific profile. The victims usually have the same hair color and are of the same race and ethnicity.
Serial murder as defined by the FBI is, “[t]he unlawful killing of two or more victims by the same offender(s), in separate events" (Morton Robert J. Ed, & Hilts., Ed, 2005, p. 9). Numerous people disagree with the definition, this researcher included, since it lacks the cool- down period after they murder, which various people feel stands necessary for serial killer status. Serial killers remain a rare phenomenon. The FBI states, serial murder accounts for less than one percent of killings per year (Morton Robert J. Ed, & Hilts., Ed, 2005, p. 2). Nevertheless, throughout the years, countless people have researched serial killers since they commit such heinous crimes. Criminologists and researchers have been attempting to identify various
I chose to explore the idea of bad math in court’ because ever since I was a child, my mother always said to me: “No matter what you choose to do in life, it’ll always require mathematics.” She said this as a way to encourage me to take my math classes more seriously (and it worked!) When watching an episode of criminal minds, my mom’s saying came into mind and I was left wondering if what my mom said was true. Once my teacher introduced this Math IA project, I took it as the perfect opportunity for me to explore an issue that had been bugging me for a while, which was: Math in Court. However, when I was doing a little but of background information...
Forensic science has now been recognized as an important part of the law enforcement team to help solve crimes and cold cases. The advances in technology are being used each day and we must continue to strive to develop better advances in this field. The recent discovery of using DNA in criminal cases has helped not only positively identify the suspect, but it has helped exonerate hundreds of innocent individuals. “With new advances in police technology and computer science, crime scene investigation and forensic science will only become more precise as we head into the future.” (Roufa, 2017) Forensic science and evidence helps law enforcement officials solve crimes through the collection, preservation and analysis of evidence. By having a mobile crime laboratory, the scene gets processed quicker and more efficiently. Forensic science will only grow in the future to be a benefit for the criminal justice
In the 1970’s, Robert Ressler, who was the previous director of Violent Criminal Apprehension Program with the Federal Bureau of Investigation (FBI), coined the term “serial killer”. He did so because when he was a child, the police in England used to refer to murders such as this as “crimes in a...
They argue that the typical serial murderer travels around, usually state to state, searching for victims to rape, torture, and murder. Very few murders are driven by delusions and are not medically or legally sick. Serial murderers are usually psychopaths who lack internal control and has an excessive need to control and dominate others. Serial murderers know right from wrong but simply do not care. Their target usually involved innocent strangers who have certain physical features or may just be accessible. The authors study the motivation of mass murders and note difficulties police officers encounter in capturing them. (Levin & Fox,
Today, technology has affected our global surroundings in a number of ways. Technology has created a more advanced society and economy. We use technology in every aspect of life today. New innovations and technology helps create a safer atmosphere and reduces the rate of crime. Technology is the usage and knowledge of techniques or is systems of these things. Usage of technology in the criminal justice system is not new but more apparent today. Technology in criminal justice will continue to challenge us to think about how we turn information into knowledge. Due to new technology, criminal investigations are able to maintain and improve their processes. Forensic science, DNA, other and future technology has all had a tremendous impact on criminal investigation and its process.
The criminal investigation process is able to achieve justice to a great to a great extent. They are effective in achieving justice, as they are able to balance the rights of the victim, offenders and society and also provide fair and just outcomes. For these reasons, the criminal investigation process is largely able to achieve justice.
