(WA State) Pedestrian Hit and Run

Hello!

So today as I am driving home from work I am sitting at a red light waiting for traffic so I can make a right turn. A spot a hole and begin to turn when the pedestrian who had been there this whole time decides to go. I had assumed since he waited so long that he was going the other direction, but I still should have looked.

Anyway as I am turning he walks into me. I rolled down my window to ask if he was okay, fully ready to turn around and meet him somewhere to give him my info. But he just kept walking, eventually jogging out of the intersection and out of sight!

I feel terrible and now I am worried because there were a lot of people there as well as cameras (not red light cameras, not sure if that makes a difference). But since he ran off I just headed home.

Do I have anything to worry about in case one of the people at the intersection decides to call the cops? I feel terrible and am so worried, but since he was able to essentially run out of the intersection I assume he is fine?

Any help would be appreciated.

Thanks
