Undated courtesy photo of Mahamud Said Omar. Omar, 46, a former janitor at a Minneapolis mosque, is to go on trial in federal court Oct. 1, 2012 on charges of conspiracy and providing material support to the terrorist group al-Shabaab. The group, which merged with al-Qaida this year, is waging an ever-diminishing campaign of violence for control of Omar’s native Somalia. Beginning in late 2007, 20 or more men with Twin Cities ties returned to Somalia to train and fight for the group. The FBI investigation into the exodus became known as “Operation Rhino,” and Omar is one of 18 men eventually charged in the case. Eight of those charged are fugitives, two are dead and seven have entered guilty pleas. Absent a last-minute plea bargain, Omar will be the only “Rhino” defendant to take his case to a jury.
