Georgia Cappleman, deputy assistant state attorney, told the jury of 10 women and two men assembled in a Tallahassee, Florida, courtroom that defendant Katherine Magbanua helped to broker a murder-for-hire and that co-defendant Sigfredo Garcia pulled the trigger, killing Markel in the driveway of his Tallahassee home while Garcia’s friend Luis Rivera helped.
