Investigators are providing an update on letters mailed to Kansas lawmakers containing a suspicious white powder.

 

The Kansas Bureau of Investigation and the Federal Bureau of Investigation with assistance from the Kansas Department of Health and Environment and other partners say now approximately 100 letters containing suspicious white powder have been received across the state of Kansas as of last night. Locally, State Senator Virgil Peck and State Representative Ron Bryce received one of these letters.

 

A small sample of the letters containing powder was sent to a laboratory that specializes in testing biological samples. Preliminary tests have returned from this lab indicating the substance is presumptively negative for common biological agents of concern. Further and more complete testing will be conducted on this sample, as well as on additional letters that have been collected, in an effort to determine the components of the substance.
