Evidence
This type of evidence is typically found at crime scenes and includes items like fingerprints, DNA, or weapons.
What is physical evidence?
This branch of forensic science is concerned with analyzing blood patterns found at crime scenes to reconstruct events.
What is blood spatter analysis?
This is the term used for the unique pattern of ridges and furrows found on the tips of your fingers.
What are fingerprints?
This is the first step a crime scene investigator should take when they arrive at a crime scene to ensure no evidence is disturbed.
What is securing the crime scene?
This molecule, found in almost every cell of the body, contains the genetic blueprint that can be used for identification.
What is DNA (deoxyribonucleic acid)?
This forensic technique involves analyzing a suspect's blood, hair, or other biological material to match it with evidence from a crime scene.
What is DNA analysis?
The size and shape of this type of bloodstain often indicate the force with which it was produced, such as from a blunt object.
What are impact spatter stains?
This type of fingerprint pattern is the most common, making up about 65% of all fingerprints.
What are loops?
This term refers to the process of identifying, gathering, and preserving evidence from a crime scene in a manner that maintains its integrity.
What is evidence collection?
This process is used to make multiple copies of DNA from a small sample, making it easier to analyze.
What is PCR (Polymerase Chain Reaction)?
These small, trace amounts of materials, such as fibers, hair, or soil, can link a suspect to a crime scene.
What is trace evidence?
This term refers to the specific angle at which blood strikes a surface, and it can be used to determine the position of the victim.
What is the angle of impact?
The first person to use fingerprints for identification in criminal investigations was this British scientist.
Who is Sir Francis Galton?
This piece of forensic equipment is commonly used to take high-quality photographs of a crime scene before any evidence is touched.
What is a camera?
This part of the DNA molecule is unique to each individual and is used to match DNA samples from a crime scene to a suspect.
What is a DNA profile or genetic marker?
The term for evidence that can be seen with the naked eye, like a weapon or a piece of clothing.
What is macro-evidence?
This type of bloodstain pattern is created by blood being dropped from a height, often appearing as a series of small droplets.
What are drip patterns?
This type of fingerprint pattern has a swirling pattern and makes up about 30% of fingerprints.
What are whorls?
When investigating a crime scene, investigators use this type of evidence to help reconstruct the crime, often including items like fingerprints or blood spatter
What is physical evidence?
This technique is used to separate DNA fragments by size and can help identify specific DNA sequences.
What is gel electrophoresis?
In this type of investigation, evidence such as hair or fiber is collected, but it might not be immediately visible to the naked eye.
What is a forensic investigation of trace evidence?
This is the term used to describe the direction in which blood has traveled, which can help identify the source of the blood.
What is the blood’s trajectory?
What is the study of fingerprints called?
What is dactyloscopy?
The method of mapping or recording the exact locations of pieces of evidence at the crime scene is known as this.
What is crime scene documentation?
This type of DNA, which comes from the mitochondria of cells, is passed down maternally and is used in cases where nuclear DNA is too damaged.
What is mitochondrial DNA?
