A federal judge is slated to hear a change-of-plea request from a 29-year-old Topeka man accused of helping another man who plotted to bomb a northeast Kansas military installation last year.

The hearing is scheduled for Monday in Topeka.

Alexander E. Blair previously pleaded not guilty to charges that he helped 21-year-old John T. Booker in his plot to plant a 1,000-pound bomb at the Fort Riley military base to aid the Islamic State group. Booker has pleaded guilty and acknowledged the plot.

Authorities say Blair loaned Booker $100 for a storage space for the explosives and failed to inform law enforcement of the plot.

A federal court document says Blair has decided to change his plea because he believes the government collected enough evidence to convict him of conspiracy.
