Forensic Science

The salary of a Forensic Fingerprint Examiner can vary depending on location, experience, and employer. On average, they can earn between $40,000 to $100,000 per year. Senior examiners with more experience and advanced certifications can earn higher salaries.

because people do not think minute molecules or cells can tell a story.its hard to believe that blood can speak to people much as soil and other micro-bacteria can tell how someone was killed...some believe science can not explain everything.

Fingerprints were first used to solve crimes in 1892, when they were instrumental in the conviction of a burglar in Argentina. This case marked the beginning of the widespread use of fingerprints as a forensic tool in criminal investigations.

Securing a crime scene involves restricting access to only authorized personnel, documenting who enters and exits the scene, preserving evidence by not tampering with it, and maintaining the scene until law enforcement completes their investigation. It's crucial to establish a perimeter, protect evidence from contamination or destruction, and follow proper chain of custody procedures.

Because each person has a unique set of fingerprints, investigators can determine if a certain person was in a certain place, or touched a certain object, or drove a certain vehicle.

There is always some uncertainty in its use as evidence because a print is seldom a complete and perfect one, and because you usually cannot determine exactly when a print was made. It is extremely difficult but not impossible to fake a print, or to move one from one object to another, or to place an object at a crime scene that already has a person's fingerprint on it.

But it can be powerful circumstantial evidence, such as when prints are found on a gun or other weapon, or in a victim's blood.

Forensic Anthropology is the study of human skeletal remains, and the decomposing of them. A lot of times they have to put the skeleton together to see how the person was built or what may have happened when they lived and died. They also determine what the person may have looked like in real life or how tall they were. You do use biology as an Forensic Anthropologist but your main focus is on the human anatomy. A Forensic Biologist is more concerned with cell structure and disease. They are looking for what could have happened in the cells that killed that person like an unknown disease or a undetected poison. But they are also in charge of looking at the structures of say a plant they found at the crime scene that they have to determine it's cell structure to figure out were it grows to find the possible primary crime scene.

When you touch something you leave your fingerprints on it, and everyone's fingerprints are unique. Therefore, if a particular person's fingerprints are found on an object involved in a crime, then that suggests the person those prints belong to was involved.

Blood spatter evidence can be analyzed to determine the direction, angle, and velocity of blood at the time of impact, which can help recreate the events of a crime. This information can be crucial in corroborating or refuting witness statements and suspect testimonies, even long after a crime has occurred. Advanced forensic techniques and technology continue to improve the analysis of blood spatter evidence, making it a valuable tool in solving cold cases.

Karl Landsteiner is known for his work in blood grouping, which laid the foundation for modern blood typing and transfusion medicine. Dr. Leone Lattes is known for his contribution to forensic science through the development of a method to determine blood type from dried bloodstains, known as the ABO blood group system.

Having a criminal background may make it challenging to secure a job in forensics, as many positions require a clean record due to the sensitive nature of the work. However, each case is unique and some employers may consider other factors such as the type of offense, rehabilitation efforts, and time elapsed since the incident. It is best to be honest about your background during the hiring process.

There is no widely recognized 22-step processing methodology for crime scene investigations. Crime scene processing techniques can vary depending on the agency or organization conducting the investigation. However, common steps in crime scene processing typically involve securing the area, documenting the scene, collecting and preserving evidence, and analyzing and interpreting the findings.

A rough sketch for a crime scene should include the layout of the scene showing the position of key elements like evidence, bodies, and relevant objects. It should also note measurements, distances, and any other relevant details that can help investigators analyze and reconstruct the scene accurately. Additionally, it should include labels and a key for easier understanding.

Crime scene evidence can be analyzed in forensic laboratories, which are specialized facilities equipped with tools and techniques to examine and process a wide range of evidence such as DNA, fingerprints, trace evidence, and documents from crime scenes. These laboratories are staffed with forensic scientists who are trained to analyze evidence and provide expert testimony in court.

Investigators can analyze hair evidence found at a crime scene to determine the hair's root structure, color, length, and possible DNA content. This information can help link a suspect to the crime scene, identify potential suspects, or exclude innocent individuals from suspicion. Hair evidence can provide valuable insights into the timeline of events, possible physical attributes of the perpetrator, and help build a timeline of the crime.

Yes, fingerprints can be traced back to a person by matching them with a known fingerprint database. However, this process requires specific equipment and expertise to analyze the fingerprints accurately.

Valid evidence from a crime scene, such as physical evidence like fingerprints or DNA, can be analyzed and compared to suspects or databases to help link individuals to the crime. This evidence can also be used to establish timelines, reconstruct events, and corroborate witness statements. Additionally, evidence can help detectives identify potential motives and build a strong case for prosecution in court.

"When it comes to a crime scene investigation, the events that take place are recognition of the crime scene, documentation of the scene, finding of the evidence, collection of the evidence, and finally analyzing all of the evidence collected."

The average salary for a forensic investigator in Wisconsin is around $60,000 to $70,000 per year. However, this can vary depending on the specific location, level of experience, and the employing organization.

A crime scene investigator is responsible for collecting and analyzing physical evidence at a crime scene, while a detective is responsible for investigating crimes, gathering information, interviewing witnesses and suspects, and solving cases. Essentially, a crime scene investigator focuses on the physical evidence aspect, while a detective handles the overall investigation.

Fingerprinting is used to solve crimes by collecting and analyzing unique patterns of ridges and valleys on an individual's fingers or palms. These prints can be compared to a database of known prints to identify suspects or link individuals to a crime scene. Fingerprints are considered valuable evidence in court due to their uniqueness and reliability in identifying individuals.

Fingerprint analysis is the oldest biometric technique used successfully in solving crimes, dating back to the late 19th century. It has been a critical tool in law enforcement for identifying suspects and linking individuals to crime scenes due to the uniqueness and permanence of fingerprints.

Detectives use forensics to solve crimes by collecting and analyzing physical evidence from crime scenes, such as fingerprints, DNA, fibers, and gunshot residue. This evidence can help connect suspects to the crime, establish timelines, and reconstruct events that occurred. Forensic analysis can also help generate leads, corroborate witness statements, and provide crucial information for building a case against a suspect.

Forensic scientists look for blood at a crime scene because it can provide evidence of the identity of the individuals involved, the type of weapon used, the sequence of events, and the location of the incident. Blood spatter patterns can also help recreate the crime scene and establish what occurred during the crime.

A paleo-anthropologist is similar to a biological anthropologist as they both study human evolution, biological adaptations, and the behavior of early humans, but a paleo-anthropologist specifically focuses on the study of fossil evidence and ancient hominins to understand human origins and evolution.
