The New Haven Police Department (PD) employs numerous strategies in an effort to crack cold cases.
One frequent method is re-examining physical evidence with more sophisticated tools that weren't accessible at the time the crime was committed. New methods for examining DNA, fingerprints, and other types of evidence have become available because to developments in forensic science. Investigators may also re-interview previously interviewed individuals, such as witnesses or others with ties to the case, in the hopes of gaining new insights.
Public participation is another approach that can be taken. In an effort to find resolutions to cold cases, several police departments may make public statements about them in the media or on social media.
Cold case investigations are sometimes a joint effort between local law enforcement and federal or state entities. Cold case units or individual detectives may be assigned to investigate cold cases by various police agencies.
Each situation is different and calls for a specialized response. The police approach may vary depending on a number of factors, including the case's length, the quality and quantity of evidence, and the involvement of suspects or witnesses. Nonetheless, law enforcement organizations prioritize solving cold cases since doing so can bring closure to families and victims' rights to justice.
