Lucy Kazdin in “Duane Barry”

I actually called you down here for another reason, Agent Mulder. Uh... in the x-rays, the surgeon found several pieces of metal - In his gums, in his sinus cavity, and one in the abdomen. I had them checked, I felt you'd want to know... and there were tiny drill holes in his left and right rear molars. A dentist who examined them said they could not have been done with any of the current equipment in use.. not without chipping or damaging the tooth. Anyway, I thought you ought to know.
