Phoenix police are renewing a long-dormant investigation and calling on the public to help track down a suspect in a 2010 sexual-assault case that went cold. Detectives have publicly identified Christian Stasenka as the man they are seeking and say he reportedly fled the country. Anyone with information is urged to contact Silent Witness at 480-WITNESS (480-948-6377).
According to FOX 10 Phoenix, the lead ties back to an investigation originally opened in 2010. Police released Stasenka’s name as part of a fresh push to reach possible witnesses or anyone who may know his whereabouts. The station’s February 14, 2026 item did not include further details about where the assault occurred or whether any charges were filed.
Why detectives revisit cold cases
Cold cases are not always closed for good. Investigations are often revived when new tips surface, fresh forensic testing becomes available, or agencies share information across jurisdictions. The U.S. Department of Justice’s Office of Justice Programs has reported that improved DNA analysis and dedicated cold-case units have helped law enforcement reopen older sexual-assault and homicide investigations across the country.
How to pass tips to investigators
Silent Witness takes anonymous tips by phone at 480-WITNESS and through an online tip form, and the organization emphasizes that callers can keep their identities confidential. For more on how to submit information or to review any reward details, visit Silent Witness.
The renewed public appeal is a reminder that even years-old cases can get new traction when information surfaces. FOX 10 Phoenix first reported this latest outreach, and investigators say they intend to follow up on any credible leads that come in. This story will be updated if authorities release further details.
