The gunman who fatally shot five service members at a Chattanooga, Tennessee, military center this week suffered from depression, CNN reports his family said in a statement Saturday.
"It grieves us beyond belief to know that his pain found its expression in this heinous act of violence," the family said of Mohammod Youssuf Abdulazeez, 24, who was shot to death by police on the scene, in their first public comments.
The shooting is being investigated as a potential act of domestic terrorism.
"There are no words to describe our shock, horror, and grief," the family wrote. "The person who committed this horrible crime was not the son we knew and loved."
