Early reports suggested that the killings resulted from a romantic dispute between Cho and Emily Hilscher, one of his first two victims. However, Hilscher's friends said she had no prior relationship with Cho and there is no evidence that he ever met or talked with her before the murders.  In the ensuing investigation, police found a suicide note in Cho's dorm room that included comments about "rich kids", "debauchery", and "deceitful charlatans". On April 18, 2007, NBC News received a package from Cho time-stamped between the first and second shooting episodes. It contained an 1,800-word manifesto , photos, and 27 digitally-recorded videos in which Cho likened himself to Jesus Christ and expressed his hatred of the wealthy.  He stated, among other things, "You forced me into a corner and gave me only one option. ... You just loved to crucify me. You loved inducing cancer in my head, terror in my heart and ripping my soul all this time".
