The 19-year-old Smadi had been scheduled for trial starting Dec. 7, but the judge found the case was complex and agreed more time was needed to interview witnesses and review evidence.
Authorities allege Smadi parked a truck in a garage beneath a the downtown office tower in September. Once he was at a safe distance, Smadi dialed a cell phone he thought would detonate a bomb in the truck, but the device was actually a decoy provided by FBI operatives posing as al-Qaida members.
