The gunman, identified as Ethan Blaine Nieneker, 32, also shot and killed Target employee Hector Leopoldo Martinez Machuca, 24.

Adam Chow, 65, and his 4-year-old granddaughter were killed alongside a Target employee in the triple homicide.

The Austin Police Department has identified the suspect and the victims in the triple homicide outside a North Austin Target.

Ethan Nieneker faces capital murder charges for allegedly shooting three people, including a 4-year-old girl, during a carjacking at an Austin Target store.

"We were just sitting there debating on going into the store, you know, and we heard gunshots and people running for their lives," said Leonard Moore, a witness to the deadly shooting in a North Austin Target.

The three people killed outside a Target in Austin, Texas, on Aug. 11 were identified, including a 4-year-old and a store employee.
