Iowa Division Of Criminal Investigation
The Iowa Division of Criminal Investigation (colloquially known as DCI) is the state bureau of investigation for the U.S. state of Iowa. DCI provides investigative support and expertise to law enforcement and public safety agencies operating within Iowa and collaborates with local, state, and federal authorities in the investigation of a variety of criminal activities. History The DCI was originally founded as the Bureau of Criminal Investigation (BCI) in 1921 under the direction of state attorney general Ben Gibson. The BCI consolidated all state law enforcement officers who were appointed by the Governor and the Attorney General into one centralized agency. Organization The DCI is a component of the Iowa Department of Public Safety. Bureaus The main components and associated sub-components of the Division are: Offices For purposes of field operations, DCI separates the state into four geographic zones, each of which has a staff of special agents and professional suppo ...

Missing Person
A missing person is a person who has disappeared and whose status as alive or dead cannot be confirmed as their location and condition are unknown. A person may go missing through a voluntary disappearance, or else due to an accident, crime, death in a location where they cannot be found (such as at sea), or many other reasons. In most parts of the world, a missing person will usually be found quickly. While criminal abductions are some of the most widely reported missing person cases, these account for only 2–5% of missing children in Europe. By contrast, some missing person cases remain unresolved for many years. Laws related to these cases are often complex since, in many jurisdictions, relatives and third parties may not deal with a person's assets until their death is considered proven by law and a formal death certificate issued. The situation, uncertainties, and lack of closure or a funeral resulting when a person goes missing may be extremely painful with long-lastin ...

Barrow Gang
The Barrow Gang was an American gang active between 1932 and 1934. They were well known outlaws, robbers, murderers and criminals who as a gang traveled the Central United States during the Great Depression. Their exploits were known all over the nation. They captured the attention of the American press and its readership during what is sometimes referred to as the 'public enemy era'. Though the gang was notorious for the bank robberies they committed, they preferred to rob small stores or gas stations over banks. The gang was believed to have killed at least nine police officers, among several other murders. The gang was best known for two of its members, Bonnie Parker and Clyde Barrow, an unmarried couple. Clyde Barrow was the leader. Other members included: * Clyde's older brother Marvin "Buck" Barrow * Buck Barrow's wife Blanche Barrow * W. D. Jones * Henry Methvin * Raymond Hamilton * Joe Palmer * Ralph Fults Gallery File:Buck and Blanche FOIA FBI.jpg, Blanche and Buck B ...

United Airlines Flight 232
United Airlines Flight 232 was a regularly scheduled United Airlines flight from Stapleton International Airport in Denver to O'Hare International Airport in Chicago, continuing to Philadelphia International Airport. On July 19, 1989, the DC-10 (registered as N1819U) serving the flight crash-landed at Sioux City, Iowa, after suffering a catastrophic failure of its tail-mounted engine due to an unnoticed manufacturing defect in the engine's fan disk, which led to the loss of many flight controls. Of the 296 passengers and crew on board, 112 died during the accident, while 184 people survived. It is also the deadliest single-aircraft accident in the history of United Airlines. Despite the deaths, the accident is considered a prime example of successful crew resource management because of the large number of survivors and the manner in which the flight crew handled the emergency and landed the airplane without conventional control. It is known as "The Impossible Landing" and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hot Lotto Fraud Scandal
The Hot Lotto fraud scandal was a lottery-rigging scandal in the United States. It came to light in 2017, after Eddie Raymond Tipton, the former information security director of the Multi-State Lottery Association (MUSL), confessed to rigging a random number generator that he and two others used in multiple cases of fraud against state lotteries. Tipton was first convicted in October 2015 of rigging a $14.3 million drawing of MUSL's lottery game Hot Lotto. Eddie Tipton ultimately confessed to rigging lottery drawings in Iowa, Colorado, Wisconsin, Kansas and Oklahoma. Also involved in the scheme were his brother and former Texas justice of the peace Tommy Tipton and Texas businessman Robert Rhodes. Eddie Tipton was sentenced to 25 years in prison. A $14.3 million prize for the Hot Lotto draw on December 29, 2010, had been left unclaimed for nearly a year, when attempts were made to claim the prize on behalf of an anonymous, off-shore trust company in Belize. The claim was rejected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iowa State Patrol
The Iowa State Patrol (ISP) is the state patrol organization in the state of Iowa. Currently, there are just over 267 officers in the patrol, roughly 183 troopers short of their authorized strength of 455. The State is broken int16 Districts Their primary concern is enforcing motor vehicle laws, but they also assist with other incidents. These incidents include riots, prison disturbances, labor related disturbances, and providing security at sporting events. The Iowa State Patrol falls under the jurisdiction of the Iowa Department of Public Safety, which also runs the Iowa Division of Criminal Investigation, also known as DCI. History The State Patrol was created in 1935 (as the Iowa Highway Safety Patrol), after an act creating the Patrol was passed by the legislature and signed by the Governor. Initially the patrol was composed of 50 men. Later that same year, the word Safety was dropped from the name, and the unit became known simply as the Iowa Highway Patrol. In 1972, the w ...

Trace Evidence
Trace evidence is created when objects make contact. The material is often transferred by heat or induced by contact friction. The importance of trace evidence in criminal investigations was shown by Dr. Edmond Locard in the early 20th century. Since then, forensic scientists use trace evidence to reconstruct crimes and to describe the people, places, and things involved in them. Studies of homicides published in the forensic science literature show how trace evidence is used to solve crimes. Trace evidence is important in accident investigation, where the movement of one part against another will often leave a tell-tale mark. Such analysis is of great use in forensic engineering. Examples Vehicular accident reconstruction relies on some marks to estimate vehicle speed before and during an accident, as well as braking and impact forces. Fabric prints of clothing worn by pedestrians in the paint and/or road grime of the striking vehicle can match a specific vehicle involved in a ...

Toxicology
Toxicology is a scientific discipline, overlapping with biology, chemistry, pharmacology, and medicine, that involves the study of the adverse effects of chemical substances on living organisms and the practice of diagnosing and treating exposures to toxins and toxicants. The relationship between dose and its effects on the exposed organism is of high significance in toxicology. Factors that influence chemical toxicity include the dosage, duration of exposure (whether it is acute or chronic), route of exposure, species, age, sex, and environment. Toxicologists are experts on poisons and poisoning. There is a movement for evidence-based toxicology as part of the larger movement towards evidence-based practices. Toxicology is currently contributing to the field of cancer research, since some toxins can be used as drugs for killing tumor cells. One prime example of this is ribosome-inactivating proteins, tested in the treatment of leukemia. The word ''toxicology'' () is a neocla ...

Questioned Document Examination
In forensic science, questioned document examination (QDE) is the examination of documents potentially disputed in a court of law. Its primary purpose is to provide evidence about a suspicious or questionable document using scientific processes and methods. Evidence might include alterations, the chain of possession, damage to the document, forgery, origin, authenticity, or other questions that come up when a document is challenged in court. Overviews Many QDE involve a comparison of the questioned document, or components of the document, to a set of known standards. The most common type of examination involves handwriting wherein the examiner tries to address concerns about potential authorship. A document examiner is often asked to determine if a questioned item originated from the same source as the known item(s), then present their opinion on the matter in court as an expert witness. Other common tasks include determining what has happened to a document, determining when a d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DNA Profiling
DNA profiling (also called DNA fingerprinting) is the process of determining an individual's DNA characteristics. DNA analysis intended to identify a species, rather than an individual, is called DNA barcoding. DNA profiling is a forensic technique in criminal investigations, comparing criminal suspects' profiles to DNA evidence so as to assess the likelihood of their involvement in the crime. It is also used in paternity testing, to establish immigration eligibility, and in genealogical and medical research. DNA profiling has also been used in the study of animal and plant populations in the fields of zoology, botany, and agriculture. Background Starting in the 1980s, scientific advances allowed the use of DNA as a material for the identification of an individual. The first patent covering the direct use of DNA variation for forensicsUS5593832A was filed by Jeffrey Glassberg in 1983, based upon work he had done while at Rockefeller University in the United States in 1981. ...

Fire Investigation
Fire investigation, sometimes referred to as origin and cause investigation, is the analysis of fire-related incidents. After firefighters extinguish a fire, an investigation is launched to determine the origin and cause of the fire or explosion. Investigations of such incidents require a systematic approach and knowledge of basic fire science. Investigating fires The difficulty of determining whether arson has occurred arises because fire often destroys the key evidence of its origin. Many fires are caused by defective equipment, such as shorting of faulty electrical circuits. Car fires can be caused by faulty fuel lines, and spontaneous combustion is possible where organic wastes are stored. A fire investigator looks at the fire remains, and obtains information to reconstruct the sequence of events leading up to the fire. One of the challenging aspects of fire investigation is the multi-disciplinary basis of the investigator's job. As fires can be caused by or involve many i ...
