Cold Case Investigations in Hawaiʻi

A Case Should Never Go Cold

At 808 Investigations, the team believes no case should ever go cold. When a loved one becomes the victim of an unsolved crime, the uncertainty can last for years. The goal is to help families pursue answers, develop new leads, and bring renewed attention to cases that may have gone inactive.


808 Investigations often refers to these matters as unresolved cases rather than “cold cases.” The focus remains on continued effort, renewed review, and the possibility of new leads. Cases may go quiet, but they are not forgotten.


For those seeking professional investigative assistance in challenging situations, 808 Investigations provides investigative support for unresolved cases, with the goal of developing new leads and helping families move closer to answers.


Law enforcement and the FBI often consider a case “cold” when a violent crime or major felony, such as homicide or sexual assault, remains unsolved after one to three years and available investigative leads have been exhausted. These cases may no longer be actively worked day to day, but they often remain open while agencies wait for new information, improved forensic technology, or credible tips.


Cold cases can also involve missing persons, especially when time passes without answers. When there is no statute of limitations, cases may remain open indefinitely and can be revisited when new leads emerge.


Missing Persons and Unsolved Disappearances

Some unresolved cases begin as missing person investigations. When someone disappears and time passes without answers, families are often left with uncertainty and unanswered questions.

808 Investigations provides investigative support in cases involving missing persons and long-term disappearances throughout Hawaiʻi. This may include reviewing existing case information, identifying overlooked leads, conducting lawful investigative research, and helping families document new information that may assist law enforcement or support responsible media outreach.

Families searching for assistance with missing persons investigations, unsolved disappearances, or cold case investigations in Hawaiʻi may contact 808 Investigations for a confidential consultation.
