I haven't watched the bodycam video (it's just not my thing personally,) but by all accounts the Officer wants her to turn the Pot off, Sonya Massey goes over to do that, and then at some point he shoots her.
Both Officers even had a delayed reaction at trying to give her medical attention.
The article gives out more in depth detail than I have, plus there is the Bodycam footage if you really want to see it with your own two eyes.
