Forensics: Tools of CSI

The video tutorial explains various forensic techniques used to link a suspect to a crime scene. It covers the analysis of glass shards using refractive index, fiber comparison through microscopy and chromatography, and footprint analysis to identify shoe type and match impressions. These methods help construct a profile of the criminal, leading to the suspect's identification.

What forensic technique is used to compare glass shards from a crime scene with those found on a suspect?

• Fiber microscopy

• DNA sequencing

• Refractive index comparison

• Fingerprint analysis

How are different types of fibers identified under a microscope?

• By their color

• By their size

• By their texture

• By their shape

What method is used to analyze the dyes in cotton fibers?

• Liquid chromatography

• Mass spectrometry

• Gas chromatography

• Paper chromatography

What is used to create an impression of a suspect's shoe?

• Silicon powder

• Carbon powder

• Aluminum powder

• Graphite powder

What is almost as unique as a fingerprint in identifying a suspect?

• Glass shard

• DNA sample

• Fiber type

• Foot impression
