Off-duty officer will not be charged in fatal Costco shooting
The DA said the case was taken to the grand jury after witnesses refused to cooperate with investigators and issued subpoenas to force them to testify before jurors.
Sanchez's injury to his head as a result of the confrontation with French was likely a key component in the decision not to indict, according to Hestrin.
"One of the pieces of information that I think was uncontroverted was that the off-duty officer was struck by Kenneth French ... and he went down as he was holding his infant child," Hestrin told a news conference. "And it all happened very fast, about less than four seconds from the moment that [French] struck to the moment that [Sanchez] fired."
Sanchez believed there was an active shooter situation and reached behind his head to check for blood multiple times, witnesses testified.
