The Witchita Police Department (WPD) may employ the following methods while looking into cold cases:
Using cutting-edge forensic tools like DNA analysis and fingerprint matching to the initial case investigation's evidence and forensic reports.
Looking back to the original investigation to see if there are any new leads or information that can be gleaned from the case files, evidence, and witness statements.
The process of re-interviewing suspects, victims, and witnesses to glean new information and spot discrepancies in their stories.
Making use of computers and forensics databases to track down leads and identify suspects.
Using incentives, collaborating with the media, and social media to solicit participation and collect data from the public.
Sharing knowledge and resources with other law enforcement organizations including the FBI and local prosecutors.
Having seasoned investigators look into cold cases on a regular basis in the hopes of finding fresh leads.
It's crucial to keep in mind that the specifics of each cold case may necessitate a different approach from law enforcement. It's possible that the Wichita Police Department has its own unique approach to solving cold cases.
