In April 2015, John Booker attempted to detonate what he believed was a 1,000 pound bomb outside the fence of Fort Riley, Kansas. It turns out the fake bomb had been coordinated with the FBI:
Booker acknowledged in court that he told one of the FBI informants that he wanted to kill Americans and engage in violent jihad on behalf of the Islamic State group. His plea agreement said he made a video in April 2015 telling Americans “today we will bring the Islamic State straight to your doorstep.”
In court, Redmond once referred to Booker as Muhammad. Booker had an alias, Muhammad Abdullah Hassan.
