Computer Evidence

Digital Evidence Digital evidence is information stored or transmitted in dual formation that may be used in court. It can be found in a computer hard drive, cell phones, a personal digital assistant (PDA), a CD, flash card in a digital camera, are just a few places were this type of information can be found. Digital evidence is normally connected with electronic crime, or e-crimes, for example child pornography or credit card fraud. (Justice, 2010) The case that I have chosen is Dennis Lynn Rader or better known as the BTK killer. Mr. Radar was arrested on February 25, 2005, after a 31 year investigation that began on January 15, 1974 with his first four victims. Mr. Radar terrorized the Witchita, Kansas, area from the 1970’s to the 90’s he was finally caught and charged with 10 counts of first degree murder and sentenced to 10 consecutive life terms in prison. (Findlaw, 2005) Mr. Radar sent three letters in the 1970’s to the media and the police taking pride in the horrific crimes that he committed. After a 25 year silence during which there were no confirmed communications from Mr. Radar he resurfaced from his silence in March 2004 leaving packages and clues for authorities. One of these clues was a floppy disk which was sent to a local television station. This disk was promptly traced to Rader through a computer at his church. Law enforcement also noticed Mr. Radar white van at drop-off areas in which security cameras filmed. Law enforcement was also able to obtain a DNA sample from Rader's daughter, which helped strengthen their case against him. Finally, bringing the 31 yearlong investigation to a close. (Hansen, 2006) In the BTK case this disk helped law enforcement locate who the BTL killer was, by using a forensic tool called EnCase discovering a deleted file on the drive.…...

How Technology Effects Sports

...Technology has changed in last years and it is everyday improving, being adapted to the necessities of people. Sport around the world is important due to the fact that technology in sports has evolved over the years and change the way that everybody sees it nowadays. Clearly, this situation has allowed that increase the performance of athletes in training or developing equipment that help them to be more competitive. However, this technology is not available for all countries because, it will require financial resources from companies or people like stakeholders to invest in this. Although some critic are disagree, there is some evidence that the consequence of technology will be positive for society. One advantage of technology in sports is the application assisting the umpires or referees. For example “instant replay” is used in some countries to help make the right call (decision). Additional another tool that has been applied by umpires is “hawk-replay”, the name of a computer and camera system which traces a ball's trajectory, aid the information is analyzed electronically and sent to the referee's headset or a device on them wrist. This is evident in sports such as the National Football League, the National Basketball Association, Major League Baseball and International Cricket.

Motion Capture Technology

...civilization. But in real time, it's been just three years since the Rise movie. In the world of motion picture technology, though, that's an eternity. Long enough to create computer graphics gear robust enough to take out of the studio and deep into a real forest. And long enough that moviemakers no longer need to give a recognizable Hollywood star top billing to bring in audiences. In fact, if you passed the leading man of Dawn—Andy Serkis—on the street, you wouldn't recognize his face at all, for you never see it on the screen. That's because his performance in the woods (actually, forests near Vancouver, not San Francisco) wasn't fillmed traditionally, it was motion captured, and used as a framework for a computer-created realistic digital ape, Caesar. And, for the first time in my knowledge, it's the performances of the motion capture actors, not the regular actors portraying humans, that are getting all the good reviews from critics; there is even talk of the first best-actor Oscar nomination for a motion-capture performance. Motion capture enables moviemakers to create realistic non-human characters—including Gollum in Lord the Rings, the Na’vis of Avatar, and the intelligent chimpanzees and orangutans of Rise of the Planet the Apes. It has also let moviemakers digitally tweak human characters, aging Brad Pitt in The Curious Case of Benjamin Button. The technology uses a network of carefully calibrated monochrome cameras that track the movements of reflective......

Technology Changing How Student Learn

... Technology Changing How Students Learn, Teachers Say There is a widespread belief among teachers that students’ constant use of digital technology is hampering their attention spans and ability to persevere in the face of challenging tasks, according to two surveys of teachers being released on Thursday. Monica Almeida/The New York Times Hope Molina-Porter, an English teacher in Fullerton, Calif., worries that technology is deeply altering how students learn. The researchers note that their findings represent the subjective views of teachers and should not be seen as definitive proof that widespread use of computers, phones and video games affects students’ capability to focus. Even so, the researchers who performed the studies, as well as scholars who study technology’s impact on behavior and the brain, say the studies are significant because of the vantage points of teachers, who spend hours a day observing students. The timing of the studies, from two well-regarded research organizations, appears to be coincidental. One was conducted by the Pew Internet Project, a division of the Pew Research Center that focuses on technology-related research. The other comes from Common Sense Media, a nonprofit organization in San Francisco that advises parents on media use by children. It was conducted by Vicky Rideout, a researcher who has previously shown that media use among children and teenagers ages 8 to 18 has grown so fast that they on average spend twice as much time......

The Evolution of Serial Killers in Popular Culture

...Amy Hankins LE300 capstone: serial killers as heroes in popular culture Final Project The Evolution of serial killers and societies fascination A serial killer is someone who is known as a friend, father, co-worker, politician, in fact a serial killer can be anybody. For centuries stories about serial killers have graced the covers of newspapers and magazines. Many famous stories have influenced a lot of films that have been produced and continue to be produced. There is an endless amount of questions as to how serial killers become serial killers, which falls under nature vs. nurture. “The causes of psychopaths remain a mystery. We don’t even have a satisfactory answer to the question of whether psychopath is a product of Mother Nature or a feature of upbringing (Brogaard & Marlow, 2012).” Nevertheless, due to the many serial killers that plague this country, they have come from a very unstable background mostly during the childhood years. Within this essay I would like to discuss not only what has been learned throughout the semester but also bring to light the possible reasons as to why serial killers kill and why society has such an enormous fascination with them. According to the dictionary a serial killers is a person who commits two or more murders at different times. Serial killers are extremely intelligent and some have most likely obtained a degree of some sort. This sort of intelligence is evident in Mr. Brooks, Dexter, silence of the lamb and perfume. ......

How Technology Change

...invention of the first automobile in 1885, there have been a number of additions and improvements. The automobile is a technology that has changed society dramatically over the last century. But not only society changed, the technology of the motorcar itself has changed significantly. Few parts of our society have seen advancements as incredible as those seen in the automotive market during the past decade. Think about it. Ten years ago, automakers were touting the number of cup holders in the cabin. Today, automakers are boasting about hands-free mobile communication technologies, fuel economy you couldn’t have dreamed about 10 years ago and life-saving technologies that help drivers avoid accidents. Today, cars are a lot safer, reliable, and more entertaining than they once were. Could you imagine being in a car that didn't have brakes or indicators? There would be madness and chaos on the roads. No other area of automotive technology has advanced more than safety. In 2001, the average car had at least two airbags. Today, vehicles have at least four, with some models equipped with up to 10 airbags. And airbags themselves also have improved, with seats that can determine a passenger’s weight and adjust airbag inflation force accordingly, or even inflatable second-row seatbelts to keep your kids snug and safe in case of a collision. Even more amazing than airbag technology, however, are the advancements in accident avoidance. Just try and purchase a car today that doesn’t......

What Makes Serial Killers Kill

...What Makes Serial Killers Kill Naomi R. Bowles Valley College Author’s Note Written for Psychology: taught by Isaac Hatley What Makes Serial Killers Kill Looking back through the years there have been many serial killers. There are many throughout the country and even many that have killed in West Virginia. Many psychologists have tried to study serial killers and answer why serial killers kill and also if serial killers suffer from some type of psychological disorder. Doing my research I find that this is a task that is very hard to do. It is difficult to determine possibly because many serial killers turn out to be the people who you would least likely suspect. In this paper I will take a look as to whether serial killers may suffer from psychopathy. I will also attempt to focus on one particular serial killer – Dennis Rader – BTK. Psychology Of A Killer Many psychologists believe that psychological disorders are the only reason for the killings while other psychologists believe that the reason is the environment that they are raised in and/or are currently in. Seeking help when a person is young, if sadistic or animal cruelty behavior is caught early by their caregiver, can reduce the factors of becoming a serial killer. There also may be factors with nature and nurture and how that may have affected them in the creation of a future serial killer. According to my research, the most successful serial killers are people who blend into society who possibly could be......

Btk Killer

...CJ2670 Mr. Chism 10 October 2013 Case study Dennis Rader also known as the BTK killer was one of the more infamous serial killers in our world. He sent letters describing the details of the killings to police and to local news outlets during the period of time in which the murders took place. Evidence such as these letters were major factors in proving Rader was the killer. Although most evidence did not need to be used the authorities gathered plenty of it to connect him to the murders. Because Rader did not contest his guilt, most evidence was not tested in court. However, physical and circumstantial facts that would have corroborated Rader as the BTK killer include: * Rader's grammar and writing style match letters and poems received from BTK, though none of his communications were handwritten, but typed, stenciled, stamped with a stamp set, or computer generated. * A pay phone that the killer used to report a murder in 1977 was located a few blocks from Rader's place of work (ADT Security) at the time. * Rader had attended Wichita State University in the 1970s. Wichita Police Detective Arlyn G. Smith II and his partner George Scantlin traced BTK's photocopied communications to two photocopy machines, one at Wichita State University and a second at the Wichita Public Library. BTK murder victim Kathryn Bright's brother Kevin, who was shot twice by BTK, reported that the killer had asked him if he had seen him at the university. A poem in one of the......

Problems Facing Human Service Clients and How They Are Helped

...Problems Facing Human Service Clients and How They Are Helped Amanda Blue BSHS/305 February 23, 2015 Joanne Schrock Problems Facing Human Service Clients and How They Are Helped There are many problems in the world today that human service clients are faced with, and are not limited to just a few. There is no one person with one single problem which is shy it is so important that the “whole person” is helped. Some of the problems that plague clients today are innumerable, but I will attempt to elaborate on a few. Human Service workers ensure that children live in safe homes and have their basic needs met. Helping parents to take care of their children may include in assisting with applications for food stamps or low-income housing and helping them to locate appropriate childcare. Housing or the lack of housing is one of the issues facing Human Service clients today. Many people are without homes for various reasons, such as not having money to pay, which means they are jobless, or not making enough to cover their living expenses. A client that is homeless can be faced with many other issues simply because they have no place to live. Another challenge for Human Service clients is depression. Depression can come about when a client is not able to adequately live with the necessities of life and seem to have no means in which to acquire them. When a client cannot provide for him or herself, it is detrimental to their well-being and may bring on a bout of......

How Technology Is Changing Marketing

...always sit easily together. Getting creative marketers to work alongside technical staff can be a huge challenge. To explore these issues, the Guardian, in association with software firm Adobe, invited a panel of five top marketers and digital chiefs to discuss the matter before an audience of about 50 marketing and digital professionals. The question they addressed was: “What does the merging of technology and marketing mean for marketers?” The panel examined the challenges of bringing together these two distinct worlds. Marketing is concerned with understanding people’s motivations and using these insights to create campaigns that promote brands and encourage people to buy their products. It is a creative and often intuitive process. The technology used to achieve this, however, requires skills in mathematics, statistics and computing. How can these two different areas work together effectively? As Guardian News and Media’s chief digital officer Tanya Cordrey told the panel: “Where marketing hasn’t changed is the creativity and the passion from brands that have really helped build loyalty and emotion.” But she added: “Those things you still need, but almost all aspects of marketing have changed very dramatically.” Three areas of marketing which have been transformed by digital are the speed, relevance and reach of campaigns. Mark Singleton, head of sportsbook marketing at betting brand Paddy Power, recalled an incident in the Premiership last March when......

...Helena Eliasson LIBRARTS SOC220 Prof. Edith Linn 7 March 2009 The BTK Killer – Dennis Rader Brief Biography Dennis Rader, who was William and Dorothea Rader’s firstborn son, came into this world on March 9, 1945. After his birth in Pittsburg, Kansas, the family moved shortly thereafter to Wichita, Kansas. As a child, Dennis seemed to be a normal kid with no special interests that could be perceived, by his surrounding society and family, as abnormal or perverted. Little they all knew about what was going on in his fantasies and in his privacy. The young boy Rader was an average student at his elementary school and through his school years he stayed mediocre with weak grades. Dennis has been described by people who knew him back then, as a well-mannered lone wolf who wasn’t really interested in staying socially active. In 1966, Dennis joined the U.S air force and served them for four years. He married Paula Dietz in 1971, shortly after his homecoming, and the two of them eventually had two children, Brian and Kerri. Rader earned an associates degree in electronics in 1973 and started his studies at Wichita State University the same year. It was about to take him an additional six years to earn a degree at the university, and all he had to show for it was C minus or D level grades. Dennis Rader lived a pretty normal life, seen from the perspective of an outsider, and after being let go by the air craft manufacturing company he worked for, in 1973, he got a job......

Lat1 - Serial Killers

...LAT1 - Serial Killers Abstract This paper that was written explores how a person is born innocent, and evolves into a monstrous and calculated serial killer. It will mention several different specific serial killers and their histories to support the facts. Another area that is explored is the difference between mass murderers and serial killers. Many times theses terms are used simultaneously; however the fact is that they are different. Reviewing the classifications, behaviors, motives, childhood neglect, sanity, and how profiling and other methods will assist in catching a serial killer. Understanding and studying serial killers can help in preventing them to start killing, or in catching them before they continue killing. Research shows that the problem of serial killing can be addressed by understanding its causes, identifying common behaviors and motivations of serial killers, and using this information to develop tools for law enforcement to prevent initial or repeated killings If a person commits a murder, it doesn’t constitute to be tagged a serial killing. I will be including material in order to define what serial killer is, and why we are so obsessed with understanding them. To fully discuss and understand serial killers, we must first distinguish the differences between them and mass murderers. The term mass murderer is often used interchangeably; however, the two terms are technically different. Mass murder occurs when a large number of......
