(CNN) -- A federal judge on Friday ordered a North Carolina teacher to remain in custody until her trial over an alleged plot to behead witnesses who testified against a would-be terrorist. Nevine Aly Elshiekh was arrested with Shkumbin Sherifi on January 22. Just nine days earlier, the man they were allegedly in collusion with -- Hysen Sherifi, who is Shkumbin Sherifi's brother -- was sentenced to 45 years in prison for being part of what prosecutors called a "violent jihad" that had conspired to kill people overseas and kill a federal officer. A criminal complaint alleges that Elshiekh and the Sherifi brothers tried to pull off a plan to "murder and behead" three people who testified against Hysen Sherifi at his trial last year.
