What? did he miss the first time? They need to count the used casings if there are any.
I’m guessing he fired off a shot to get attention/have someone call the police? Or maybe he was the one that made the 911 call and there wasn’t but one shot (the one that officers saw).
Around here, a gunshot won’t rouse a call to the police at all. Right now, it’s squirrel, dove, Canada goose, and pesky varmint season!
