Fingerprints
This is the type of fingerprint that cannot be seen with the naked eye.
What is a latent fingerprint?
This material is ideal for preserving tire track evidence.
What is plaster casting?
This term refers to the placement of dots on “i’s” and crosses on “t’s” in handwriting analysis.
What are diacritics?
Deleted files can often be recovered from this section of a computer’s memory.
What is unallocated space?
This is the reason a counterfeit detection pen leaves a dark mark on fake bills printed on regular paper.
What is the high percentage of starch in regular paper?
The unique ridge characteristics in a fingerprint are referred to as this.
What are minutiae?
These impressions are created when a shoe makes a mark in soft soil.
What are plastic impressions?
Erasures in documents are most often detected using this type of light.
What is UV light?
This challenge complicates the collection of digital evidence due to privacy and security.
What is data encryption and volume?
Banks often use this specific technology at the teller window to verify a customer’s identity and help prevent check fraud.
What are biometric signature pads?
Fingerprints that appear in soft materials like wax or clay are known as these.
What are plastic fingerprints?
Investigators can determine the gait and direction of movement of a suspect
What are shoe impressions?
This method separates the ink components of a questioned document.
What is chromatography?
This biometric technology identifies individuals using fingerprints or signatures.
What is biometric verification?
At a crime scene, investigators find a size 13 shoeprint. Based on just the shoe size, this is a reasonable assumption they can make about the suspect.
What is that the suspect is tall?
This fingerprint pattern contains two deltas and a core.
What is a whorl?
Tool marks are classified as this type of evidence
What is class evidence?
Handwriting analysis is considered this because it depends on the examiner’s expertise.
What is subjective?
Retina scanners and biometric pads primarily assist with this.
What is verifying identity?
To link a suspect to a bite mark found on a victim, investigators must first do this with the suspect’s teeth.
What is make a cast of the suspect’s teeth?
The scientific study of fingerprints is called this
What is dactyloscopy?
The first step in preserving tire track evidence is this.
What is photographing the tracks?
Guiding the spelling or punctuation when collecting handwriting samples makes the evidence this. Is this something you should or should not do?
What is something you should not do?
Digital evidence is easily tampered with due to this inherent weakness.
What is it can be edited or altered?
Features like line quality, spacing between letters and words, and the slant of letters are all examples of these in handwriting analysis.
What are handwriting characteristics (or points of comparison)?
To determine if a loop is radial or ulnar, you must know this critical detail.
What is which hand the print came from?
Shoe size impressions can help determine this about a suspect.
What is the suspect's height and weight?
This feature of handwriting examines the pressure applied to the page while writing.
What is pen pressure?
This method ensures deleted data cannot be easily recovered from a device.
What is data wiping?
This type of minutiae occurs where a friction ridge in a fingerprint comes to a sudden, abrupt stop.
What is a ridge ending?
This fingerprint preservation technique involves dusting with a contrasting powder and then photographing it.
What is lifting a fingerprint?
Tool marks found on doors or windows can identify this about the tool used.
What are brand or type of tool?
Experts often compare handwriting based on this visible slant of letters.
What is writing style consistency?
Digital evidence like emails and metadata must meet this legal requirement to be admissible in court.
What is chain of custody?
From tire impression evidence at a crash or crime scene, investigators can determine this about the relationship between the tires and the vehicle they’re mounted on.
What is whether the tires are original to the vehicle or not?
