There are some parts of that story that seem strange.
1, they had to bring in an ATV to get there, but they shot someone that came out of the remote woods at dark. Wonder what happened and how it played out.
2, They rendered first aid. and the shooter was arrested and charged, yet they are conducting an investigation. Wonder why (if it actually happened) they charged with 2nd degree assult. Based on the fact that one person was shot? Accidents happen, but charging right out of the gate seems like a bad idea.
Just seems to me there are some gaps here, or reporting that leaves somethings to be better understood.
