Though investigators have yet to pin down a motive in the attack, they are probing whether Garcia was driven by extremist ideologies, a law enforcement source told CNN.
Among those killed were two elementary school-aged sisters; three members of a Korean American family, including a child; a mall security guard; and a young engineer.
Law enforcement does not yet feel they have a “complete picture” of Garcia’s past and are continuing to dig into his background, a law enforcement source told CNN.
The child’s name and age were not given, but the Texas Department of Safety did note a three-year-old child was among those killed.
Other victims included Christian LaCour, an outlet mall security guard, and Aishwarya Thatikonda, who was killed while visiting the mall with a friend, CNN affiliate WFAA reported.
