The Ohio Bureau of Criminal Investigation (BCI) provides visibility and investigative resources to help local law enforcement agencies resolve unsolved homicides. Through this database, BCI provides details and photos related to unsolved homicides and solicits tips from the public to assist local law enforcement in pursuing their investigations.
BCI defines an unsolved homicide as a homicide or questionable death that remains unsolved after being reported to law enforcement and for which there are no apparent viable leads.
By highlighting cold cases through the Ohio Attorney General's Office, BCI and local law enforcement agencies can:
- Bring widespread visibility to a case
- Increase the likelihood that tips may help bring a perpetrator to justice and victims' loved ones a sense of closure
- Compare details of cases in their jurisdictions with unsolved homicides elsewhere, helping to identify linked cases
To request that an unsolved homicide be included in BCI's statewide database and featured on this website, Ohio law enforcement agencies should contact BCI at 855-BCI-OHIO (224-6446) or e-mail OhioUnsolvedHomicides@OhioAttorneyGeneral.gov and reference Ohio Unsolved Homicides.
