Forensic Science

What kind of DNA ..?

Blood you need to find the type

Hair or fibers you can find the ethnicity

Teeth you can differentiate bite marks

Blood, saliva and semen can be used as individualized evidence in court

A person who works with bodies in forensics is called a forensic anthropologist or a forensic pathologist. They are responsible for examining human remains to determine the cause of death and provide evidence for criminal investigations.

PCR is commonly used in forensic identification work because it allows for the amplification of small amounts of DNA found at a crime scene, making it easier to analyze. It is a sensitive technique that can generate enough DNA for analysis even from degraded or old samples. PCR also allows for the comparison of DNA profiles between samples, aiding in the identification of suspects or victims.

1. Secure the area by establishing a perimeter to restrict access.
2. Document the scene by taking photographs and making detailed notes.
3. Search the scene for evidence and collect, label, and preserve it properly.
4. Conduct a thorough examination of the scene, noting any patterns or clues.
5. Interview witnesses and gather statements to gather information about the crime.
6. Release the scene only after completing all necessary evidence collection and documentation to avoid contamination.

DNA is a powerful tool in forensic science due to its uniqueness to each individual, which allows for precise identification. DNA evidence is reliable, accurate, and can be used to link individuals to crimes or exonerate the innocent. It has revolutionized forensic investigations by providing strong evidence in court cases.

A biohazard bag should be used to collect evidence in situations involving blood, bodily fluids, or other potentially infectious materials. This is necessary to protect the individuals handling the evidence from exposure to harmful pathogens and to prevent contamination of the evidence.

Forensic botanists collect plant material such as leaves, flowers, seeds, pollen, and wood samples found at crime scenes. They also analyze plant fibers, spores, and microscopic plant structures to determine their origin and link them to crime scenes or suspects. Additionally, plant DNA analysis is used to identify plant species and individuals within plant populations.

Sam Ryan was played by Amanda Burton, who currently stars as the headmistress in the TV show Waterloo Road.

Some different methods of crime scene search include grid search, spiral search, strip search, and quadrant search. These methods help ensure thorough coverage and collection of evidence from the scene. The choice of method may depend on the size and terrain of the crime scene, as well as the resources available.

Pollen at a crime scene can be collected using techniques like tape-lifting, vacuuming, or swabbing. The collected samples can then be analyzed under a microscope to identify the types of pollen present, which can help link suspects or objects to the scene.

Some pioneers of forensic science include Edmond Locard, who established the basic principles of forensic science, Alphonse Bertillon, who developed anthropometry as a system for identifying individuals, and Sir William Herschel, who used fingerprints as a means of identification. Their contributions laid the foundation for modern forensic science techniques.

Forensic scientists use fibers found at a crime scene to link suspects to the scene or victim based on similarities in color, type, and composition. They compare the fibers under a microscope and analyze them to provide evidence in criminal investigations. Fibers can also help establish timelines of events and connections between different locations or individuals.

You can volunteer at local police departments, crime labs, or forensic science research institutions to gain experience as a forensic science technician. Contact these organizations directly to inquire about volunteer opportunities and any requirements they may have for volunteers in this field.

DNA is important because of its tremendous discriminating power and stability. Following are the role of DNA in forensic science.

-

It is used for successful resolution of many crimes.

-

To identify potential suspects who’s DNA may match evidence left at crime scenes.

-

To exonerate persons wrongly accused of crimes.

-

It helps to identify crime and catastrophe victims.

-

To establish paternity and other family relationships.

-

It helps to identify endangered and protected species as an aid to wildlife officials (could be used for prosecuting poachers).

-

To detect bacteria and other organisms that may pollute air, water, soil, and food

-

It helps in match organ donors with recipients in transplant programs.

-

To determine pedigree for seed or livestock breeds.

-

To authenticate consumables such as caviar and wine.

The average salary for a forensic scientist in Georgia is around $57,000 per year. However, this can vary based on experience, location, and specific job responsibilities.

Forensic scientists examine soil by collecting samples from crime scenes using standardized methods. They analyze these samples in the lab to identify the soil's composition, mineral content, and any potential contaminants. This information can help link suspects to crime scenes or provide critical evidence in criminal investigations.

first you go the crime scene.

second you take notes about the crime scene

third you dust around for fingerprints, gunshot residue etc

fourth you interview the bystanders and witnesses, record all their comments

fifth you take pictures of the crime scene

and finally you release the crime scene tot he public with a statement

idk if it is correct but it seems pretty real

Characteristics of fingerprints used for matching prints include ridge patterns, minutiae points (ridge endings, bifurcations), and ridge spacing. These unique features create a fingerprint that is distinctive to an individual and are commonly used in forensic analysis for identification purposes.

Becoming a forensic scientist typically requires a bachelor's degree in a relevant field such as forensic science or biology. Some positions may require a master's degree or higher depending on the specialization. Additionally, ongoing training and professional development are important to stay current in the field.

Tire tracks are collected by photographing them from various angles, making plaster casts if the tracks are in soft ground, lifting the tracks using specialized adhesive lifters, or collecting physical samples of the tire impressions using casting material. The collected evidence is then carefully packaged and stored to prevent damage or contamination.

DNA is commonly used in forensics to identify individuals through their unique genetic code. By analyzing DNA samples from crime scenes and comparing them to known DNA profiles, forensic scientists can match suspects to evidence or exonerate innocent individuals. This can help solve crimes, identify victims, and provide valuable evidence in investigations.

The three types of imprint evidence are footwear impressions, tire impressions, and tool marks. Footwear impressions are left behind by shoes, tire impressions by vehicle tires, and tool marks by tools or objects in contact with a surface. They are useful in forensic investigations to identify the source of the imprint.

The human skin has oils and moisture on the surface. These adhere to the surfaced that you touch and leave the fingerprint patterns there. They may also be pressed into dirt, oil and other items already on the surface.

Yes, pollen can be considered trace evidence as it can be used to link a person or object to a specific location. Pollen can be transferred between individuals or objects, providing valuable information in forensic investigations.

Forensic scientists can extract DNA from various sources found at a crime scene, such as blood, saliva, hair follicles, skin cells, and semen. These samples are collected carefully and analyzed in the lab to identify potential suspects or victims based on their DNA profile.
