The investigation of the suspicious letters sent to legislators and public officials has expanded beyond Kansas.

The FBI will now be the agency leading the investigation. The KBI will continue to work with all law enforcement partners to bring these incidents to a resolution. KBI Director Tony Mattivi says their focus remains on ensuring the safety of Kansans and holding those responsible for these crimes accountable. Since the first letters were handled and reported by officials, the KBI had over 60 special agents, forensic scientists and employees devoted to collecting or screening evidence or managing and tracking responses to the incidents. Additionally, 17 hazmat teams and 12 bomb squads responded across the state.

It remains important to be vigilant when handling mail. Report any letters containing an unknown white powder to the KBI at 1-800-KSCRIME or the FBI at 1-800-CALL-FBI.
