Daniel Milzman, a 19-year old sophomore at Georgetown University, has been charged with producing the deadly toxin ricin in his dorm room. He faces a federal court hearing Tuesday. The FBI claims Milzman bought the precursor materials to make the poison at stores including Home Depot and American Plant. A recent Georgetown graduate claims Milzman made aggressive comments against another student in recent months and told the college’s administrators. Court documents show the picture of a student in his dorm room using his iPhone to research the process of making ricin, later wearing goggles and a dust mask while making the poison.
