Took my son on his first big game hunt this last weekend in 23 for mulies. Hunted hard all day with no luck and on our way home came upon a woman and teenagers that had just hit a buck on the highway. They clipped it with the drivers front corner so both of the animal's front legs were snapped at the knees and it was trying to jump up and run unsuccessfully. It could only move about 2 feet at a time. We were the only 2 vehicles on the stretch of highway. They were taking pictures of it suffering and yelling at the mom for texting and not paying attention to the road SMH... I pull over and they're crying and standing around as it makes it's way to the ditch by the road side. Panting, moaning, and just miserable. So I got out of my truck and asked if anyone had called 911 yet. They said no that they didn't know what to do. So I told one to call and to get back and that they'd hear a gun shot. Planned to fire one round directly into the back of the skull to put it out of it's misery. Got my glock, walked back toward the deer and then I hear someone laying on their horn and tires screeching to a halt. I holster and look up and it's law enforcement. From my point of view, we were 40-50 minutes from any town or city and no one had called 911 yet so I thought it could take a while for someone to show up and that it was the right thing to do for the animal. The officer took care of business and we didn't get a chance to speak because cars had piled up going both directions and I needed to get my truck out of the way. Anyone here know the legalities of this? Back east growing up that's what everyone did. Law enforcement would pull up, thank you for putting it out of it's misery and then write a salvage tag. I'm wondering if laws are different here in AZ and if I could have been charged with something based on the officer's demeanor?? Scares the crap out of me that I don't know the answer to that and run in to this situation often with where I live. I've been digging around and can't figure out if it's a violation or a crime? Anyone know the straight answer?
