~ Criminal cases brought before the courts are generally
separated into three categories: misdemeanors, felonies, and
treason. ~ Misdemeanors are lesser offenses settled with fines or
forfeiture of property, and some are punishable with a jail
sentence of less than one year. ~ Misdemeanors are lesser offenses
settled with fines or forfeiture of property, and some are
punishable with a jail sentence of less than one year. ~ Felonies
are far more serious crimes that result in harsher penalties such
as being sentenced to a state or federal penitentiary for one year
or longer. ~ They include assault cases, drug sales, various white
collar crimes and other deeds that are harmful to people or
society. Felony crimes such as homicide may also be eligible to
receive the death penalty in some states. ~ Treason is defined as
any act that violates allegiance to your own country. Originally
this primarily referred to war crimes, but over the years the most
common form of treason has become the selling of government secrets
to hostile countries.

~ The criminal justice system is comprised of three separate
parts: police enforcement, court system, and criminal corrections.
~ When the police arrest a suspect who will be tried, the legal
system must first determine the location where the case will be
tried. ~ The term jurisdiction describes the legal authority to
hear a legal matter and make an official ruling. Jurisdiction
establishes where each trial will take place. ~ There are three
separate factors to consider when making the decision of which
court will try a case: geographic location, type of crime, and
subject.

~ Actus reus is the Latin term used to describe a criminal act.
Every crime must be considered in two parts-the physical act of the
crime (actus reus) and the mental intent to do the crime (mens
reus). ~ To establish actus reus, a lawyer must prove that the
accused party was responsible for a deed prohibited by criminal
law. ~ Actus reus is commonly defined as a criminal act that was
the result of voluntary bodily movement. ~ This describes a
physical activity that harms another person or damages property.
Anything from a physical assault or murder to the destruction of
public property would qualify as an actus reus.

Bullets that have been fired at the scene of any crime will be
examined in the hopes of discovering several pieces of information.
The actual bullets can identify what type of gun the criminal used
and whether or not the firearm is connected to any other crime. The
amount of damage a bullet has sustained upon hitting a hard surface
can help determine approximately where the shooter was standing,
what angle the gun was fired from, and when the gun was fired. Any
residue on the bullet can be studied and compared to residue on the
hand of a suspect, on the gun that was fired, or on any object that
was close by when the firearm was used. This information helps
researchers uncover the identity of the shooter. When the bullets
are missing, the type of impact they made can lead investigators to
ascertain what kind of bullet the criminal used, and therefore the
type of gun as well. Studying the markings found on a bullet or the
impact a bullet made on any surface can establish exactly which gun
the criminal used. Every firearm produces a slightly different and
unique pattern on the shell-casing it fires; the bullet will
therefore imprint a distinct pattern upon anything it hits. Once
scientists have identified these markings they can easily match
them to the appropriate firearm. There are many experts deeply
involved in this study, and they are frequently called upon to help
solve crimes. Ballistics details are also commonly input into a
large database that can be accessed by law enforcement agencies all
across the country. When someone enters new data, the computer
locates any relevant data from previous investigations. This
information can lead to the discovery of the owner of a particular
weapon, and assist in tracking down the guilty party who fired the
gun.

Finger Prints Forensic scientists have used fingerprints in
criminal investigations as a means of identification for many
years. Fingerprint identification is one of the most important
criminal investigation tools due to two aspects of fingerprints:
their persistence and their uniqueness. The word persistence refers
to the fact that fingerprints do not change over time. The friction
ridges which create fingerprints are formed while inside the womb
and grow proportionally as the baby grows. Permanent scarring is
the only way a fingerprint can change. The word uniqueness
acknowledges that fingerprints are unique to an individual. Even
identical twins have been shown to have different fingerprints
Types of Prints In general, the purpose of collecting fingerprints
is to identify the fingerprint- leaver. This person may be the
suspect, a victim, or even someone else who happened to be at the
place where the print was found. There are three types of
fingerprints that can be found: latent, patent, and plastic. Latent
fingerprints are made of the sweat and oil on the skin's surface.
This type of fingerprint is invisible to the naked eye and requires
additional processing in order to be seen. This processing can
include basic powder techniques or the use of chemicals. Patent
fingerprints can be made by blood, grease, ink, or dirt. This type
of fingerprint is easily visible to the human eye. Plastic
fingerprints are three-dimensional impressions and can be made by
pressing your fingers in fresh paint, wax, soap, or tar. Like
patent fingerprints, plastic fingerprints are easily seen by the
human eye and do not require additional processing for visibility
purposes.

Cause, Mechanism, and Manner of Death When a death occurs, a
physician or medical examiner must fill out a death certificate. In
order to properly complete this document, they must determine three
things: the cause, the mechanism, and the manner of death. There is
often confusion about which is which. The cause of death is the
disease or injury that produces the physiological disruption inside
the body resulting in death. An example of a cause of death is a
gunshot wound to the chest. The mechanism of death is the
physiological derangement that results in the death. An example of
a mechanism of death due to the gunshot wound described above is
exsanguination (extreme blood loss). Last but not least, the manner
of death is how the death came about. Manner of death can be
classified in six ways: 1) Natural 2) Accident 3) Suicide 4)
Homicide 5) Undetermined 6) Pending A natural death occurs as a
result of aging, illness, or disease. An accidental death occurs
when an injury or poisoning causes death but it is unintentional.
In this case there can be no evidence supporting the idea that the
poisoning or injury occurred with an intent to harm or cause death.
A suicide results from an injury or poisoning occurring from a
deliberate, self- inflicted act committed to harm or cause death to
one's self. A homicide occurs when death is caused by another
person. Undetermined is used as a classification when the
information pointing toward one manner of death is no more
compelling than any others. A pending death is one that is waiting
on more evidence or analysis before the examiner can make a
determination.
