A Cold Case refers to a criminal investigation, typically involving serious crimes such as murder or missing persons, that remains unsolved after a considerable amount of time and has been temporarily closed or inactive due to lack of evidence, leads, or progress. These cases are often revisited when new evidence emerges, such as advancements in forensic technology (e.g., DNA testing), new witness statements, or breakthroughs in the investigation.
Cold cases are sometimes brought back into the spotlight with the help of psychic detectives, who claim to use their abilities to provide new insights into the crime or the whereabouts of missing persons. Though the use of psychics in solving cold cases is controversial and met with skepticism, some claim it has provided valuable clues that have aided law enforcement in the resolution of such cases.
