(CNN) "Stunned." That's the word Glenda Hatchett used Wednesday to describe how she felt after seeing the dashcam footage of Philando Castile's July 2016 shooting death during a traffic stop in suburban Minneapolis.

Officer Jeronimo Yanez, a police officer in St. Anthony, Minnesota, was acquitted Friday of second-degree manslaughter and related charges in Castile's shooting. The St. Anthony Police Department later announced he would not return to the force.

"I was stunned," Hatchett, a former judge who is representing Castile's family, told CNN's Brooke Baldwin. "I was absolutely stunned. I knew, in theory, what to expect, but we all saw it for the first time when the jury saw it. I think that it really ... shows that Yanez actually panicked."
