U.S. Magistrate Judge Maria Valdez ordered the 23-year-old Henderson — who was accused of posing as Christian Banks when buying the Taurus handgun — held without bond for the time being, saying she was “very concerned about the allegations” raised by prosecutors. The judge said she was also troubled that Henderson was accused of running the trafficking scheme while out on bond on pending state weapons charges. Another hearing on Henderson’s continued detention was slated for June 5.
