When he approached, Garza said the driver threw the car in reverse and hit him, so he opened fire. But a woman with Santellana told Eyewitness News Garza never identified himself as an officer when he approached with a gun. Thinking they were being robbed, they took off.
Garza was placed on administrative leave. Santellana's family called for justice.
Now, 9 months later, both have had their day in court and a grand jury found there wasn't enough evidence to indict Garza.
Garza "received no injuries requiring medical attention," according to Harris County Sheriff's detectives.
