(MCT) — CHICAGO—Throughout Thursday’s sentencing, Tahawwur Rana’s children appeared nervous, his college son bouncing his leg rapidly and his daughter, a high schooler, leaning forward with her hands clasped tightly.

After all, their father, a former doctor and businessman who was convicted in one of Chicago’s most significant terrorism cases, now faced up to the 30 years in prison for aiding and abetting a plot to slay and behead Danish newspaper staffers because of cartoons it published of the Prophet Muhammad. Rana also had been convicted of providing support to Lashkar-e-Taiba, a deadly Pakistani terrorist organization.
