Forensic Paper

Forensic imaging is an emerging field of specialization which has been in the works ever since chalk and achromatic photography. Even before the personal computer, it was clear to law-enforcement and investigators that they needed help when ransacking through a crime-scene to gather useful information which might provide clues to “who did it.” As time went on, more resources were allocated to investigators cataloging information so that it could be reviewed as many times and by as many people without its recursive degradation. Essentially, technology has enabled us not only to derive more data from a given location, but also preserve more data as the process of investigation continues. Today, many inconsequential data are recorded in fear anything might be missed after it is too late to retrieve certain aspects of it. This is the bread and butter of forensic imaging, even as it branches out toward providing new insight to investigators, in addition to enabling them to simply review their work.


On July 21, 1957 at 11:45 p.m Roy Jones parked his 1949 blue Ford Sedan In “Lover’s Lane” in the oil field on Van Ness in Hawthorne, California. The car contained 4 teenagers, 2 boys ages 16 and 17, and to young girls who were 15. The car was approached on the driver’s side by a white male carrying a revolver. He took the victim’s car with them in it and then drove to a more secluded area in the Hawthorne oil fields. Using the shirts taken off the two boys, he bound the teenagers' hands behind their backs and began taping with adhesive tape, the eyes and mouths of three of the minors; both of the boys and one of the young girls, The boys were forced to lie on the rear floorboards of the car, and the girl in the backseat was ordered to lie back. The suspect then proceeded to rape the second 15-year-old girl who was sitting in the front seat. At 12:50 a.m. he told all of the victims to undress. He then collected the adhesive tape and their bindings and fled the location with the vehicle. About an hour later the suspect ran a red light and was engaged in a police chase in which shots were fired striking both officers were hit and then eventually died from the injuries on the scene.

The murder brought shock the people in the town of Hawthorne and wanted to whom and why would somebody do such a horrific crime. Mr. Tuley from Manhattan Beach found two watches in august of 1957, and then put them in his garage. In the course of a year the Tuley family found a revolver’s frame and cylinder, and it had one live round, 6 shells and two empty chambers. After Mr. Tuley found the objects he finally called the El Segundo Police Department. The evidence was shown to the robbery victims and they identified the watches. The ballistics of the gun identified that the gun was used to kill the police officers and the serial number was then traced to Shreveport, Louisiana to a man using the false name, G.D. Wilson and the address of a grave. The evidence tracks lead to a YMCA that the man singed in as George Wilson and a copy was made of the registration to be added to the evidence. Unfortunately when the case was reviewed again in 1997 and has become cold again with no other leads. Two main forensic techniques were used to solve the case. They were fingerprint analysis and forensic document examination (Edholm). The investigators in the case used IAFIS or Integrated Automated Fingerprint Identification System to identify the fifty year old fingerprints. IAFIS is the world’s largest biometric database created by the FBI to help solve cases. IAFIS can identify fingerprints, search criminal history, and store and distribute documents across its database. IAFIS has well over 55 million fingerprints stored to help solve crimes (Federal). The investigators compared two different documents to prove that the same man purchased a gun under a false name and visited a YMCA under a false name near the scene of the crime (Edholm). The American Board of Forensic Document Examination believes that forensic document examination is “The application of allied sciences and analytical techniques to questions concerning documents is termed forensic document examination. The examination of questioned documents consists of the analysis and comparison of questioned handwriting, hand printing, typewriting, commercial printing, photocopies, papers, inks, and other documentary evidence with known material in order to establish the authenticity of the contested material as well as the detection of alterations (FAQs).”

The Catalyst

Imagine walking on the surface of the moon, swimming through the deepest depths of the ocean, or fighting through a zombie-infested wasteland. Virtual reality is the key that will unlock the imaginations of millions to be experienced as if it was actually happening. I believe virtual reality will be a catalyst allowing computer graphics to grow and evolve into a truly realistic experience possibly changing the world along with it. Virtual reality has been in existence for many years, but thanks to the growth in technology, virtual reality has evolved into a powerful piece of technology.

Virtual reality is an awesome tool used almost everywhere. Virtual reality has begun to grow in the medical field as a form of training. Medical students can now practice and hone his of her skills on a virtual patient than on a cadaver or a real patient. With virtual reality instructors can create almost any medical situation imagined to truly prepare students for situations that may not be in a textbook. I believe that this is important because I can feel better knowing that my doctor has a lot of hands on experience straight out of the classroom.

Virtual reality is also being used to explore the ocean and areas that are unsafe to human life. Cameras can be placed on unmanned submarines allowing explorers to see and experience a shipwreck without having to be there. This also allows the explorers to assess whether it is safe or not to go down in person or continue to experience the wreckage virtually. These are only a couple uses of virtual reality, but there are many more being researched and tested expanding the reach of computer graphics and virtual reality.

In my opinion the holodeck from the Star Trek series is the next step in virtual reality. Why go outside when a trip to the moon is in the living room? Once virtual reality expands to something like the holodeck computer graphics and virtual reality will affect people’s everyday lives. I believe the virtual vacation will be one of the greatest innovations in virtual reality. Mars, the Grand Canyon, and just about anywhere else imaginable will be at the grasps of everyone. I believe virtual vacations will be an amazing step in virtual reality, but I believe virtual entertainment will be the greatest advancement in virtual reality.

Over the years companies have tried to create virtual video games and movies but they have not been the greatest evolution in virtual reality. Virtual video games will allow the user to feel as if he or she is actually apart of the action, aiming and running around trying to survive a zombie infested wasteland for example. Virtual movies will make the audience apart of the overall experience or even apart of the storyline itself.

Virtual reality is extremely important to computer graphics. It has placed computer graphics in many different fields from medicine to gaming and exploration to vacation. I believe that once virtual reality has grown into adulthood not only will computer graphics be affected but society as a whole. Virtual reality will improve society making it a better place. It will allow society to grow and evolve unlike anything before it. Innovations in technology will expand society and the virtual reality experience. I know that virtual reality is the catalyst that will rocket computer graphics into a newer and brighter future evolving and changing society along with itself.

CGT Blog Assignment 1

My paper was on the importance of virtual reality. Virtual reality is important because once it grows and evolves into technological adulthood, it will have changed not only the meaning of computer graphics and how we percieve it, but society itself will have grown and evolved around virtual reality as well.
