The death toll from last week’s mass shooting at military sites in Chattanooga, Tennessee, has risen to five. The victims include four marines and one sailor. On Friday night, more than 1,000 people attended a memorial service. The FBI is continuing to investigate the possible motive of the suspected gunman, Mohammod Youssuf Abdulazeez, who died in a firefight following the mass shooting. ABC News is reporting that FBI interviews with his parents and a diary belonging to Abdulazeez paint a picture of a disturbed, suicidal young man who used drugs and was preparing for bankruptcy.
