...Park University CJ 312 Professor Scheffner Forensic Entomology The study of insects and their relation to a criminal investigation is known as forensic entomology. Such practice is commonly used to estimate the time of death when the circumstances surrounding the crime are unknown. This determination can be carried out by studying the state of development of maggots or insect sequence of arrival (Saferstein, 201, p 77). Necrophagous insects are important in the decomposition of cadavers. Using medical techniques, such as the measurement of body temperature or analyzing livor and rigor mortis, time since death can only be accurately measured for the first two or three days after death. In contrast, by calculating the age of immature insect stages feeding on a corpse and analyzing the necrophagous species present, postmortem intervals from the first day to several weeks can be estimated. I selected cased 1, 2, and 3 for the this weeks assignment. It appears that in each case, the time elapsed between the discovery of the bodies was all different. In case 1, the remains of a female child were recovered from shallow grave on a narrow ledge in Oahu, Hawaii (Case Studies). In this case it is estimated that the child had been deceased for approximately 52 days. In case 2, the body of a female was found along a highway. The victims brother had reported her missing just four days before her body was discovered. In case 3, the body of Lori Ann Auker was discovered on a dirt road. It...

...Welcome to Homicide Forensic Science is a fundamental component of the justice system. Forensic scientists use scientific techniques and knowledge to assist law enforcement in investigations and solving crimes. They collect and analyze numerous types of evidence, including blood, body fluids; DNA; and human tissue. Forensic scientists assist the decision makers by showing the prosecutor if the issue has merit before it reaches the courtroom thereby reducing the number of cases having to be heard. Their decisions are based on scientific investigations and not circumstantial evidence or unreliable witnesses. Forensic scientists can restore faith in the judicial system with the use of science and technology for facts in criminal and civil investigations. The legal system is established on the belief that the legal process results in justice for all. History of forensic science The history of Forensic science or the applying of scientific principles to legal questions has a lengthy and interesting history. The first recorded autopsy was reported in 44 B.C was on Julius Caesar, where the Roman physician, Antistius proclaimed that he had 23 wounds on his body but only one was fatal. In 1248, a Chinese book entitled “His Duan Yu” (meaning The Washing Away of Wrongs) explaining how to tell apart a drowning from a strangulation. This was also the first recorded use of medicine to assist in solving crimes. In 1590, the first microscope was developed. In 1775, Karl...

...Expert Witness Helped Convict Wrong Man A panel of six independent forensic scientists stated, in a report filed in a Houston State court, that crime laboratory supervisor James Bolding helped convict an innocent man of rape in 1987. Because Bolding either lacked basic knowledge of blood typing or gave false testimony, George Rodriguez spent 17 years in prison for a rape that he did not commit. Bolding’s testimony in the case was challenged amid a scandal that led to retesting of evidence in 360 cases; And with the report filed, that number could increase by the thousands, involving 25 years of cases. “The panel concluded that crime laboratory officials might have offered ''similarly false and scientifically unsound'' reports and testimony in other cases, and it called for a comprehensive audit spanning decades to re-examine the results of a broad array of rudimentary tests on blood, semen and other bodily fluids” (Liptak and Blumenthal, 2004). There have been many cases where forensic science and law enforcement experts have provided sworn testimony, documents, or reports intended for the court that contain unreliable or misleading information, findings, opinions, or conclusions. Some are found to have been intentionally offered by the expert in order to secure an unfair or unlawful conviction, via ‘fitting the evidence to the crime’. A state audit of the Houston police department (HPD) crime lab, completed in December 2002, found that HPDs DNA technicians there...

...In the article it was discussing all the different types of forensics there are. People think there is just one type of forensics, but there’s a wide range of all different types. I also picked this article because I think people should realize that forensics is a very hard field to go into. You really have to really have heart to be able to go into this field. Investigator’s really have to go into detail about every little thing. In the investigations you really cannot miss a single detail. The article also goes in depth about what sciences are required to take, and for that person to really know. To be in the field you really have to love what you do. Many people often misunderstand Forensic Science and believe it is much more capable than it really is. People typically think that what they watch on T.V. is 100% true. Actually what you see on T.V. is mainly false or over exaggerated in some way. Criminal Investigation is the largest and most known form of Forensic Science. More of the known areas that people know about Forensics are; Fingerprinting, DNA Identification, Fiber Samples, Computer Animation, etc. What people see on T.V. is that it takes about an hour for the people on the NCIS, or Law & Order to figure everything. Typically it takes months at a time, and most of the time aren’t even accurate concepts. This article relates to my life, because forensics is really all about a puzzle. I feel like my life is like a puzzle. But in a good way. This article was...

...utilizing it. On the flip side, it can also be as bad; incredibly harmful at best. When a crime has been committed, in this day in age, a computer is often the accomplice. That being said, the sooner the evidence within the computer accomplice is collected by the attending computer forensics specialists, the more likely the data that has been accessed, even if deleted, is remaining evidence on the computer; whether only in part or true to form detail. The longer the forensic team takes to collect this invaluable data, the more likely it is that the computer will overwrite key pieces of evidence, which would ultimately result in the prosecution or release of a potential criminal mind. Even partial data is extracted from the hard drive of the accomplice computer; it can still be very much useful in a prosecution, as partial data is also admissible in court today (Krehel, 2011). Securing the hard drive in the exact manner in which the computer has been found is absolutely vital to any forensic expert hoping to do their job with attention to detail and accuracy. This can be done by duplicating or replicating the hard drive at the onset of any said investigation when a computer is involved. Because forensic specialists are not attorneys, it is nearly impossible for this professional to know which data to keep and what to leave behind for overwrite. In this case, the choice is clear. There isn’t one. Every shred of data on the accomplice computer must be collected ((Biles, 2010). Just...

...The crime scene is one that is a vital part of the criminal investigations process which has contributions from many areas of this component. In this case study there will be points expressed on the crime scene search, principles, crime scene photography, sketching the crime scene, fingerprint evidence, trace evidence, and biological evidence. Investigators have the responsibility to comprehend these segments in order to effectively manage and maintain a crime scene. The crime scene investigation consists of elements of criminal law, criminal procedure, and constitutional evidence. The search part of the crime scene involves a related focus which is in legal requirements. It is crucial to incorporate the Fourth Amendment in the crime scene search process which implicates the search and seizure warrant rule. Many investigators and officers are unaware of the absence of generally recognized exceptions to the search and seizure warrant rule, law enforcement officers must obtain a warrant to search a crime scene where a reasonable expectation of privacy exists. (Geberth, 2003). The procedures behind crime scene searches consist of isolating, securing, search, and document the scene, as well as obtaining physical evidence which is the physical objects linked to the order of a crime such as hairs, paint chips, fibers, and bullets. Records which are basically keeping accumulated general descriptive data of the crime scene, and witnesses. In isolating and securing the crime scene an...

...criminal, then there are some who don’t feel this way. Continue reading to decide for yourself. CSI EFFECT 3 CSI Effect What is the “CSI Effect”? Is it anything more than a myth? Actual jurors in real cases are wrongly acquitting criminals who they would have convicted if the television show CSI was not aired, as people see it as real. Prosecutors say the CSI effect forces them to explain why they have no forensic evidence, and jury selection takes longer as the people who seem to be influenced by the show are removed. Defense attorney’s agree about the effects of the television show. Producers of CSI say their show has an educational effect on the public(teaches them science). Some police feel that CSI helps educate criminals on how not to get caught. Educators think CSI attracts students to want a career in forensic science.(Knight,2010). The CSI effect does have some benefits such as understanding the use of resources to investigate cold cases and for people who have information about a crime to come forward. Donald Shelton, Greg Barak and Young Kim randomly chose 1,027 jurors in Ann Arbor, Michigan to participate in a study.

...Journal of Forensic & Investigative Accounting Vol. 4, Issue 2, 2012 The Obvious Fraud: A Short, Problem-Based Case Study to Highlight Inappropriate Fraud Examination Techniques David O’Bryan Jeffrey J. Quirin* INTRODUCTION Assume you are an internal auditor for a large, multinational, manufacturing organization with a division in Mexico. One of your responsibilities is to investigate allegations made on the company’s fraud hotline. When you arrive at work one morning you learn an anonymous tip was left on the hotline that alleges fraud involving the division manager. “Pat’s significant other is a fraudulent vendor,” was the anonymous tip left on your company’s fraud hotline. Pat is a division manager at your company. “Wow. I can’t believe this guy is so blatant,” you’re thinking as you review some accounts payable invoices while following up on this anonymous tip. The invoice that caught your attention is shown in Table 1. A quick search of the AP file reveals a total of three invoices like the one in Table 1, all for identical amounts but on different dates. The division manager, Pat, has the authority to approve payment of invoices for less than $10,000. It is obvious to you that the manager has a created a shell company. You happen to know that Pat’s significant other is named Kim, hence the name Kimco Marketing. There is no documentation to support these transactions other than the invoices, all of which are purportedly for marketing services. * The authors are, respectively...
