Well, watching the video was certainly educational.
They looked like they were across the street so I don’t see how they could have been shoveling snow into his yard for one thing.
The other is that the couple did nothing to de-escal;te the situation. They engaged fully in the dispute.
They probably had been at war with each other for a long time.
The neighbor who shot them ..... there’s no excuse for that. He really unloaded on them and you could hear them cry out in pain, then it looks like he walked across the street to finish off the job.
Why he decided to off himself, too is beyond me. But it does solve the problem of what to do with this with the justice system.
They were pushing snow from around their vehicle, straight across the street onto the front of his property.
Btw, this was not about the snow. I would bet the rent this feud had brewing going on long before this event.
