This is what I have gathered so far regarding the Garlic Festival Shooting.
Three witnesses described the shooter to look and walk like a police officer, wearing gear of police officer. One stated he was wearing a bullet proof vest.
Almost all witnesses assumed at first it was fireworks going off.
One witness said "it was like a movie"
One witness said several people shouted "active shooter, active shooter"
One witness said he thought the shooter weapon was an m4.
Lead officer whom I assume is the Sargent gave press conference, could not describe what the shooter was wearing, did not know what type of weapon was used. Did not know how many suspects.
The last witness that saw the suspect get shot in the head seemed to be smirking in the photo taken.
