Question 1

In forensic toxicology, which mass spectrometry technique is most commonly paired with gas chromatography (GC-MS) for confirming drug identifications?

Accepted Answer

Electron ionization

Answer

Electron ionization (EI) is the standard ionization method paired with GC-MS, producing reproducible fragmentation patterns that can be matched against library databases.

Question 2

Which digital forensics principle ensures that the forensic examination does not alter the original evidence stored on a digital device?

Accepted Answer

Write blocking

Answer

Write blocking prevents any data from being written to the original storage device during forensic examination, preserving the integrity of the original evidence.

Question 3

A forensic pathologist uses virtual autopsy (virtopsy) CT imaging. What is a primary advantage over traditional autopsy in certain cases?

Accepted Answer

It allows non-destructive examination before physical dissection

Answer

Virtopsy CT allows comprehensive non-destructive visualization of internal structures before any physical dissection, which is particularly valuable for religious or cultural reasons and complex trauma cases.

Question 4

In forensic document examination, which technology is used to reveal hidden or altered text by detecting differences in ink reflectance across the electromagnetic spectrum?

Accepted Answer

Video spectral comparator (VSC)

Answer

A Video Spectral Comparator (VSC) uses multiple light sources and wavelengths to reveal alterations, obliterations, and ink differences invisible to the naked eye.

Question 5

Which type of biometric technology is most commonly used in forensic identification from surveillance footage of individuals wearing masks?

Accepted Answer

Gait analysis

Answer

Gait analysis can identify individuals from surveillance footage even when facial features are obscured, as walking patterns are individualistic and difficult to disguise.
