Calvin Goddard (ballistics)
Calvin Hooker Goddard (30 October 1891 – 22 February 1955) was a forensic scientist, army officer, academic, researcher and a pioneer in forensic ballistics. He examined the bullet casings in the 1929 St. Valentine's Day Massacre and showed that the guns used were not police issued weapons, leading the investigators to conclude it was a mob hit. Biography Goddard was born in Baltimore, Maryland. After graduating from the Boys' Latin School of Maryland in 1907, he graduated with a Bachelor of Arts degree in 1911 from the Johns Hopkins University, later earning a medical degree and graduating 1915. He joined the United States Army and became a Colonel. He was also a professor of police science at Northwestern University and the military editor of the Encyclopædia Britannica. He was also the editor of the American Journal of Police Science, America's first scientific police journal. Colonel Goddard commanded the US Army Crime Laboratory in Japan for a number of years after World ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forensic Scientist
Forensic science combines principles of law and science to investigate criminal activity. Through crime scene investigations and laboratory analysis, forensic scientists are able to link suspects to evidence. An example is determining the time and cause of death through autopsies. This evidence can then be used for proof towards a crime. Forensic science, often confused with criminalistics, is the application of science principles and methods to support legal decision-making in matters of criminal and civil law. During criminal investigation in particular, it is governed by the legal standards of admissible evidence and criminal procedure. It is a broad field utilizing numerous practices such as the analysis of DNA, fingerprints, bloodstain patterns, firearms, ballistics, toxicology, microscopy, and fire debris analysis. Forensic scientists collect, preserve, and analyze evidence during the course of an investigation. While some forensic scientists travel to the scene of the ...

United States Army Military Police Corps
The United States Army Military Police Corps (USAMPC) is the uniformed law enforcement branch of the United States Army. Investigations are conducted by Military Police investigators under the Provost Marshal General's Office or special agents of the Department of the Army Criminal Investigation Division (CID). United States Army Military Police units have combat zone responsibilities in addition to their law enforcement duties. These responsibilities include mounted and dismounted patrols, response force operations, area damage control, route reconnaissance, cordon and search operations, critical site security, and convoy and personnel escorts. Operationally, these duties fall under the "security and mobility support" discipline of the Military Police Corps. Mission The United States Army's Military Police provide an important function in the full spectrum of Army operations as a member of the Maneuver, Fires, and Effects division. The Military Police Corps provides expe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bullets
A bullet is a Kinetic energy weapon, kinetic projectile, a component of firearm ammunition that is Shooting, shot from a gun barrel. They are made of a variety of materials, such as copper, lead, steel, polymer, rubber and even wax; and are made in various shapes and constructions (depending on the intended applications), including specialized functions such as hunting, Shooting sports, target shooting, training, and combat. Bullets are often tapered, making them more Aerodynamics, aerodynamic. Bullet size is expressed by weight and diameter (referred to as "caliber") in both imperial and metric measurement systems. Bullets do not normally contain explosives but strike or damage the intended target by transferring kinetic energy upon impact and Penetration (weaponry), penetration. Description The term ''bullet'' is from Early French, originating as the diminutive of the word ''boulle'' (''boullet''), which means "small ball". Bullets are available singly (as in Muzzleloader, muzz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Organized Crime
Organized crime is a category of transnational organized crime, transnational, national, or local group of centralized enterprises run to engage in illegal activity, most commonly for profit. While organized crime is generally thought of as a form of illegal business, some criminal organizations, such as terrorist organizations, terrorist groups, rebel groups, and Separatism, separatists, are politically motivated. Many criminal organizations rely on fear or terror to achieve their goals or aims as well as to maintain control within the organization and may adopt tactics commonly used by authoritarianism, authoritarian regimes to maintain power. Some forms of organized crime simply exist to cater towards demand of illegal goods in a state or to facilitate trade of goods and services that may have been banned by a state (such as illegal drugs or firearms). Sometimes, criminal organizations force people to do business with them, such as when a gang extorts protection racket, protec ...

Fingerprint
A fingerprint is an impression left by the friction ridges of a human finger. The recovery of partial fingerprints from a crime scene is an important method of forensic science. Moisture and grease on a finger result in fingerprints on surfaces such as glass or metal. Deliberate impressions of entire fingerprints can be obtained by ink or other substances transferred from the peaks of friction ridges on the skin to a smooth surface such as paper. Fingerprint records normally contain impressions from the pad on the last joint of fingers and thumbs, though fingerprint cards also typically record portions of lower joint areas of the fingers. Human fingerprints are detailed, unique, difficult to alter, and durable over the life of an individual, making them suitable as long-term markers of human identity. They may be employed by police or other authorities to identify individuals who wish to conceal their identity, or to identify people who are incapacitated or dead and thus unab ...

Special Agent
In the United States, a special agent is an official title used to refer to certain investigators or detectives of federal, military, tribal, or state agencies who primarily serve in criminal investigatory positions. Additionally, some special agents operate in criminal intelligence, counterterrorism, or counterintelligence-based roles as well, with one or all of these roles occasionally taking precedence over criminal investigatory tasks. Within the American federal law enforcement system, dozens of federal agencies employ federal law enforcement officers (LEOs), each with different criteria pertaining to the use of the titles ''special agent'' and ''agent''. Most criminal investigators employed by the U.S. Department of Defense and its component departments typically utilize the title of "special agent." Most people holding the title of "special agent" are LEOs under state and/or federal law (with some also being dual intelligence operatives such as with the FBI). Thes ...

Colonel
Colonel ( ; abbreviated as Col., Col, or COL) is a senior military Officer (armed forces), officer rank used in many countries. It is also used in some police forces and paramilitary organizations. In the 17th, 18th, and 19th centuries, a colonel was typically in charge of a regiment in an army. Modern usage varies greatly, and in some cases, the term is used as an Colonel (title), honorific title that may have no direct relationship to military. In some smaller military forces, such as those of Monaco or the Holy See, Vatican, colonel is the highest Military rank, rank. Equivalent naval ranks may be called Captain (naval), captain or ship-of-the-line captain. In the Commonwealth of Nations, Commonwealth's air force ranking system, the equivalent rank is group captain. History and origins By the end of the late medieval period, a group of "companies" was referred to as a "column" of an army. According to Raymond Oliver, , the Spanish began explicitly reorganizing part of thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trace Evidence
Trace evidence occurs when objects make contact, and material is transferred. This type of evidence is usually not visible to the naked eye and requires specific tools and techniques to be located and obtained. Due to this, trace evidence is often overlooked, and investigators must be trained to detect it. When it comes to an investigation trace evidence can come in many different forms and is found in a wide variety of cases. This evidence can link a victim to suspects and a victim or suspect to the crime scene. There are three general categories in which forensic science uses trace evidence. It can be used for investigative aids, associative evidence, and in-scene reconstructions. In terms of investigative aids, trace evidence can provide information to determine the origin of a sample and determine the manufacture date of the material, all of which can limit potential suspects in a case. Associative evidence can associate with or link victims or suspects to a crime scene. For re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Firearms
A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and operated by an individual. The term is legally defined further in different countries (see legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other explosive propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability. ...

Major is a senior military Officer (armed forces), officer military rank, rank used in many countries. When used unhyphenated and in conjunction with no other indicators, major is one rank above Captain (land), captain in armies and air forces, and one rank below lieutenant colonel. It is considered the most junior of the senior officer ranks. Background Etymologically, the word stems from the Latin word meaning "greater". The rank can be traced back to the rank of sergeant major general, which was shortened to sergeant major, and subsequently shortened to ''major''. When used in hyphenated or combined fashion, the term can also imply seniority at other levels of rank, including major general, denoting a low-level general officer, and sergeant major, denoting the most senior non-commissioned officer (NCO) of a military unit.
