A criminal complaint alleges that 20-year-old Joshua Goldberg of Orange Park, Fla., had planned to detonate some sort of explosive device at Sunday’s annual Kansas City Stair Climb, which honors 9/11 first responders each year.

WOKV reporter Stephanie Brown has been following the case.

Brown’s full report is highly recommended and can be found at the KOKV website.

“Hopefully there will be some jihad on the anniversary of 9/11,” the suspect wrote on August 17, according to the complaint.
