I lost my dog...and I had her for a little over a month

I lost my dog today. She decided to walk with a man who was walking along the road. I called, and called to her but she just kept running. The man, who tf knows who HE is, wouldn't even stop walking five minutes to let me catch her. So this guy keep doing his "power walk" workout, as Izzy runs her little brains out. I keep calling to her, but she doesn't come. So I head out to the road. The man, the dog up the road. Far ahead of me. I keep calling~ nothing. I keep walking. Pretty soon I figure 3/4 mile. I see the man way up ahead rounding the turn. No Izzy in sight. I turn around, walk home for my truck. I take the truck up the road. No man, though I have seen him a gazillion times before walking. No dog. I search side roads~nothing, so I turn around. As I come back down the road, I see a man a woman poking around by the side of the road. So I ask um, "Have you guys seen a brown dog?" They say, "ya, it got hit by a truck, and now it's gone". They told me a truck hit her. She was laying by the side of the road. The truck keeps right on going. The man who finds her goes back to his house to tell his wife. They come back out to find Izzy gone. They told me her mouth was bloody. Izzy has Humane Society Tags on. She also has a microchip, and a rabies tag from Indiana. I think I wrote my phone number on the yellow tag, along with her name. I'm thinking the worst, because that's what I do. If anyone finds her, give me an email quick like: loraxII@hotmail.com
Thanks in advance.
