Forensic Science

Criminal cases are very dependent upon evidence to prove or disprove the facts of the case. The analysis of evidence requires a wide breadth of scientific knowledge and the latest scientific techniques as well as proper evidence procedures.

What tools do anthropologists use?

Oh, dude, anthropologists use a bunch of tools, like notebooks, cameras, tape measures, and even fancy stuff like GPS devices. They also use their brains a lot, like, to analyze data and interpret cultural practices. So, yeah, it's not just shovels and brushes like in the movies.

What tools or equipment does a forensic anthropologist use?

Well, honey, a forensic anthropologist uses tools like calipers, osteometric boards, and X-ray machines to measure and analyze skeletal remains. They also use things like trowels, brushes, and screens to carefully excavate and recover bones from crime scenes. And let's not forget the good ol' camera to document everything for evidence. So, yeah, it's basically a mix of measuring, digging, and snapping pics to solve those mysteries.

What do forensic anthropologist wear to work?

Oh, dude, forensic anthropologists typically wear protective gear like gloves, masks, and lab coats to work. They want to avoid contaminating evidence or getting any funky stuff on themselves while they're digging around bones and stuff. So yeah, it's like a stylish lab look, but with a hint of crime scene pizzazz.

Why do dead bodies swell up?

Bacteria in the body forms gases which cannot escape, thus causing the bloating of the body.

In Detail:

Human body is basically made of organic materials like carbohydrates which when decompose will break up into CO2 (Carbon dioxide) and H2O (Water).

As we all know, when the state of a material changes from either solid or liquid to gas the volume of the material increases.

Due to this change of state and no way for the gases to escape, the dead body swells.

In due course of time when the gas builds up more pressure and tears up the surface to find an escape path. That is why a decomposed body is watery.

What happened in the crime Slime Number 9 by Rowland Morgan?

Oh honey, in "Slime Number 9" by Rowland Morgan, the main character, Slimy Sam, gets caught red-handed stealing a precious diamond from the mayor's wife. The whole town is in an uproar as Slimy Sam tries to slither his way out of trouble, but justice prevails in the end when he's caught and thrown in the slammer. It's a classic tale of crime and punishment with a slimy twist!

What is a forensic science plotters?

in forensic science "plotters" are often used to

A- record test results

B-determine the probable motive for a crime

C- Isolate a specific chemical from a solution

D-prevent evidence from becoming contaminated

What is the procedure for forensic fiber analysis?

Forensic fiber analysis is a critical process in criminal investigations, involving the meticulous examination of fibers found at crime scenes or on suspects. The procedure begins with careful collection and preservation of fiber evidence, using specialized tools like tweezers and evidence bags to prevent contamination. Next, forensic analysts employ various microscopic techniques, including stereomicroscopy and polarized light microscopy, to examine the fibers' physical characteristics such as color, shape, and texture. Advanced spectroscopic methods like Fourier Transform Infrared Spectroscopy (FTIR) and Raman spectroscopy are then utilized to determine the chemical composition of the fibers, providing crucial information about their origin and type. Finally, the analyzed fibers are compared to known samples or databases to establish potential matches, which can link suspects to crime scenes or provide valuable leads in investigations.

Are eyeprints a valid method of identification?

Eyeprints, also known as retinal scans, are a valid method of identification as each person's retinal blood vessel pattern is unique. They are highly secure and accurate, often used in high-security applications such as government agencies and financial institutions for authentication purposes. However, the technology required for eyeprint recognition can be expensive and less commonly found in everyday applications.

What are positive and negative impressions of latent fingerprint's?

Positive: Latent fingerprints are unique to each individual, making them valuable for forensic identification. They can be used as evidence in criminal investigations to link a suspect to a crime scene.

Negative: Latent fingerprints can be challenging to collect and preserve due to factors like surface contamination or poor print quality. They may also be prone to errors during processing and analysis, potentially leading to misidentification.

What is the quasar method?

The quasar method is a technique used in astrophysics to estimate the distances to distant celestial objects. It involves observing the spectra of quasars, which are extremely bright and distant objects, to determine the redshift caused by the expansion of the universe. By comparing the redshift of a quasar with known properties to that of a target object, astronomers can infer the distance to the target object.

What is the starting rate of pay for a forensic scientist?

The starting rate of pay for a forensic scientist can vary based on factors such as location, experience, and education level. On average, entry-level forensic scientists can expect to earn around $45,000 to $60,000 per year.

Why is determining the shape of the nose and ears difficult for a sculptor?

Determining the shape of the nose and ears can be difficult for a sculptor because they are intricate features with subtle curves and angles that can be challenging to replicate accurately in three-dimensional form. A small deviation in proportions or positioning can greatly affect the overall likeness and expression of the sculpture. Additionally, the texture and surface details of the skin on the nose and ears require precise sculpting techniques to capture realism.

What is used in forensic entomology?

In forensic entomology, insects are used to estimate the time of death based on the stages of development seen on the body. Different insect species colonize a body at different stages, helping determine how long the body has been exposed. Other factors, such as temperature and environment, also play a role in this estimation process.

How many people are employed as forensic scientists?

As of 2020, there were approximately 15,400 forensic scientists employed in the United States according to the Bureau of Labor Statistics. This number can vary based on jurisdiction and demand for forensic services in different areas.

What is the highest degree for forensic science?

The highest degree typically earned in forensic science is a doctoral degree, such as a Ph.D. in Forensic Science or a related field. This level of education is often required for advanced research positions, university teaching roles, or leadership positions in forensic science organizations.

What is the highest degree a person can get in forensic science?

The highest degree a person can earn in forensic science is typically a PhD in Forensic Science. This advanced degree allows individuals to conduct research, teach at the university level, and pursue high-level positions in forensic science organizations.

What part of teeth does a forensic odontologist look at for identification?

A forensic odontologist can make identifications from the teeth only by comparing antemortem x-rays (x-rays taken of a known individual before their death) to post mortem x-rays (x-rays taken of a body, either unkown, or presumed to be a certain individual). The shape of the teeth, pulp chambers, roots, fillings (if present), as well as the trabecular pattern of the surrounding bone, the relationship of adjacent teeth, etc., etc. One cannot simply look at a tooth (or an x-ray of a tooth or jaws) and find information which identifies the body.
