Cold Case Investigations
Re-examining unresolved cases with modern techniques and advanced analytics.
What We Do
A "cold case" is an unsolved homicide, missing persons report, or other serious crime where all initial leads have been exhausted without resolution. We understand the pain of an open-ended investigation and the need for closure. Our team of experienced private investigators specializes in breathing new life into these complex cases. We focus on the human element, the evidence, and the possibilities presented by time and technology.
