A diary belonging to Mohammad Abdulazeez speaks of martyrdom and suicidal thoughts, according to a credible report.
The diary, as reported by ABC news, documents the Chattanooga gunman's suicidal spiral, driven by drugs, money problems and a struggle with being a devout Muslim.
ABC reported that he had trouble adjusting to his 12-hour overnight shift, and took sleeping pills to compensate. He was also considering filing for bankruptcy, and was thousands of dollars in debt, ABC reported.
Though a family representative told ABC News on Sunday that there were no outward signs of radicalization, the 24-year-old was susceptible to "bad influences," and was affected by watching news accounts of children being killed in Syria.
Abdulazeez kept a number of guns in his house and often went out with friends to hunt or shoot at targets, according to an unnamed family representative. He bought ammunition for his guns as recently as July 11, when he visited the Hixson Walmart, according to FBI officials.
Federal agents are seeking the identities of the other two young men who visited the store with Abdulazeez.
Other news agencies have reported that Abdulazeez was seen at a local shooting range with several other young men.
The family said through its representative that by sending Abdulazeez to Jordan, they were attempting to keep him away from drug- and alcohol-related influences in Chattanooga, not send him on a path to radicalization.
