With more than 30 FBI agents due to arrive today in Chattanooga, a diary belonging to the gunman and FBI interviews with his parents paint a picture of a disturbed, suicidal young man using drugs, preparing for bankruptcy and facing an appearance in criminal court, according to a representative of the shooter’ s family.

Four days after the shooting, the FBI has not found any connection to overseas terrorist groups, but Mohammod Abdulazeez’s diary says that as far back as 2013, he wrote about having suicidal thoughts and “becoming a martyr” after losing his job due to his drug use, both prescription and non-prescription drugs, the family representative said.
