Martinez is 21 years old and a recent convert to Islam, and court documents describe him as obsessed with jihad. He was arrested last week in a sting operation after he allegedly tried to detonate a phony bomb. He's charged with attempted murder of federal officers and attempted use of a weapon of mass destruction.
Prosecutors are expected to argue that Martinez represents a flight risk and ask that he be detained pending trial. He was born outside the United States, although authorities haven't said where. Martinez's mother has said his father is Nicaraguan.
