These have shown that open source software is just as secure as proprietary software and in some cases, even more so given the selection of configuration management selections by programmers in the coding and completion of the open source forensic software. More fundamentally however, open source forensic software has shown the ability to scale from an architectural standpoint to support the rules-based approaches forensic analysis requires to support the digital evidence gathering process (Berghel, 2003)
The rate of growth of these threats is surpassing the ability of securities agencies and software firms to counter them (Abel, 2009). Amid this rapid growth of all forms of Internet-based crime, there have been only partially successful attempts from the leading software securities firms to alleviate this problem (Erickson, 2009)
For budget-constrained companies, municipal, state and federal organizations, this lower TCO of open source software has been one of the business drivers favoring its adoption. The perceived vulnerabilities of open source, specifically it support of security standards common across digital forensics (Forte, 2008) has been validated through a series of performance audits (Irons, 2006)
Courts (Volonino, 2003). This is significant as open source software was initially perceived by the broader it community as lacking the security, reliability and support for proprietary software (Muller-Seitz, Roger, 2009)
Open source forensic software, despite the criticisms of security, reliability and support (Abel, 2009) continues to be more agile as a development platform in responding to these threats. Open source forensics software has then progressed from fad to enterprise-wide application solution as a result (Rogers, 2003)
Open source forensics software is today being used for the identification of unauthorized access, the presentation and analysis of access points and capturing of a cybertrail that can be used as evidence in U.S. Courts (Volonino, 2003)
" Further, in my analysis, I would examine the roots of both hair samples. This is particularly important given that while variability is common in the roots of animals, animal hair root is in most cases club-shaped (Deedrick and Koch, 2004)
" The level of training arson dogs undergo makes them a very effective tool in fire, and most particularly, accelerant use investigations. It is important to note that on this front, several research studies conducted in the past have clearly indicated "that there is a higher level of positive findings for an accelerant by lab scientists in cases in which arson dogs have located the accelerant first" (Houck and Siegel, 2010, p
Forensics Scenario Discussion From the onset, it is important to note that in criminal investigations, one type of evidence commonly encountered is hair evidence (Oien, 2009)
I would also expect that if the hair came from a human, then its medulla would be darker under transmitted light. The darker medulla in this case would result from the fact that it "is often filled with air, which provides an insulating layer and thus temperature control for the person" (Tobin, 2005, p
The recent evolution DNA technology attributable to the Human Genome Project have revolutionized the field of criminal investigations more than any other single development since the introduction of identification through finger prints in the late 19th and early 20th centuries. In fact, hundreds of decades-old so-called "cold cases" have been solved in the first decade of the 21st century by applying new DNA analysis and identification techniques that were unavailable to the original investigators to physical evidence preserved since the initial investigation went cold (Johns, Downes, et al
DNA matching techniques have greatly expanded the list of potential substances and sources of reliable forensic evidence. Specifically, uniquely identifying forensic material is present in virtually all biological excretions and tissues but previous technological capabilities have limited their use pending the development of more precise forensic identification techniques (Markey, 2007)
No judge at any point in the long procedural history of the case questioned the bite-mark evidence e stringently enough to reveal its fatal flaws." (DeCoux, 2007) Due to the bitemark evidence being unquestioned, Raymond Rawson, odontologist, "took the stand and wrongly identified Krone as the source of the bitemarks on the victim's body
21 that questioned the way pathologists determine whether bite marks were inflicted before or after death." (Hall, 2003) Specifically state in the information presented is: "The majority of pathologists assume that if you have a bruise, the bite mark was made before death because you still have your blood pressure and that if you tear or break the underlying vessel, the blood is going to go into the tissue and the degradation of the red blood cells is going to make the skin look yellow, red, black, green," Avon said
Since that day in Chicago 34 years ago, bite-mark comparison has become a regular weapon in the forensic arsenal, with odontologists testifying in courtrooms hundreds of times." (McRoberts and Mills, 2004) David Faigman, University of California Hasting College of the Law professor and co-editor of Modern Scientific Evidence states a belief that bitemarks "probably ought to be the poster child for bad forensic science
" (2001) In an article published by the New York Times in January 2007 entitled: "Evidence From Bite Marks, it Turns Out, is Not so Elementary" states that is that Roy Brown, fifteen years ago, was convicted of a murder by "stabbing, beating, biting and strangling a social workers in upstate New York." (Santos, 2007) the primary evidence in this case was a bitemark, presumably left by Brown however, Brown was released from prison in January 2007 when DNA testing on the saliva that the biter left on the victim proved Brown was innocent
It also indicates an impersonality that is seldom seen with suicides. In most instances, the note is a way of explaining the action to people who the suicidal person feels will care and be hurt by the action (Opfer 2011)
If Bulls statements are true, then not only did Baker kill his wife with malice aforethought, he did so in a way in which she had absolutely no means of defending herself from her husband's machinations. At the end of the trial, Matthew Baker was convicted of murder and sentenced to a prison term of 65 years (Talbert 2010)
It is thus that technologies which work to yield that crucial data from the memory store of any such device have become so valuable to law enforcement in the age of terrorism. According to the Computer Forensics Tool Testing Program (CFTT), "a cellular forensic tool shall have the ability to logically acquire all application supported data elements present in internal memory without modification" (Ayers, 15) This is to indicate that such technology should be able to hack into mobile communication devices without detection by the subject, making it a valuable tool in investigating crimes and preventing suspected crimes
They believed that the techniques they used had "the power to identify one individual in the world's population" and also declared, "that the chance that any two people would have the same DNA print was one in 30 billion."(Neufeld & Colman 1990) Ink Dating One of the other ways to do a forensic test is known as the Ink Dating test
