He took Spanish and math classes, as well as requirements in English, history and biology. As an elective, Long took African-Centered Psychology.
Timothy Moore, who had taught the class in the past, left the university before Long arrived and did not know him. The class, he said, was a way to look at the study of psychology more broadly than the Euro-centric treatment it usually gets.
Online, Atlanta University Center students expressed frustration with the connection to Clark Atlanta, emphasizing that the school had nothing to do with his views.
One Clark Atlanta student, who identifies himself as Saan, said in a tweet that Long said in a video he “had no affiliation with any businesses other than (h)is own.”
A graduate from Morehouse who identifies himself as Drake from Canada tweeted that “CAU had no influence on his decisions.”
Prior to his time at Clark Atlanta, Long attended classes at the University of Alabama for one semester in the spring of 2012. No one from the school returned a call seeking comment about Long’s time there. At the time of the shooting, Long was a Kansas City, Mo. resident.
Like veteran Micah Xavier Johnson, who shot and killed five officers in Dallas, Long, identified as the lone shooter in the attack, had also served in the military. He was a former Marine, who served from 2005 to 2010, as a data network specialist earning the rank of sergeant. Long was deployed to Iraq for about six months in June 2008, according to information made available from the Marine Corps.
Long, who used the pseudonym Cosmo Setepenra online and sought to make it his name last year, wrote three books about detoxing and self-awareness. Amazon has since taken them down. Long posted online as a spiritual advisor and life coach.
In documents seeking the name change, Long also referred to himself as a member of a black separatist group known as the Washitaw Nation.
