Which term describes specialized units that investigate unsolved cases using new evidence or technology?

• A. Crime Analysis
• B. Cybercrime
• C. Decoy Operations
• D. Cold-Case Squads

Answer: (D)

Cold-case work focuses on reexamining unsolved cases by bringing in new evidence, techniques, or technology. Specialized units called cold-case squads are created to reopen old investigations, review overlooked details, re-interview witnesses, and apply advances in forensics (like modern DNA analysis) or digital forensics to uncover new leads or identify suspects. This approach is specifically about revitalizing cases that stalled in the past, rather than about analyzing crime patterns, prosecuting cyber offenses, using decoys, or other functions. Crime analysis deals with understanding patterns to inform policing decisions; cybercrime concerns offenses involving computers; decoy operations are tactic to trap criminals; none of these describe a dedicated team pursuing old cases with new methods, which is why cold-case squads fit best.
