What's with this?!

So after that turtle rescue mission failed, I couldn't just let another turtle be in the road like that. Yesterday I'm driving home and off to the side of the road, I see a turtle! Oh gosh! This is going down Wekiva Springs Road. For those of you who know that area you'd know there isn't any place to just turn into and stop. So I'm panicking, turning around, and then turn on my hazards in the middle double laned area. I dunno what that's called. When there wasn't any traffic I went over to the turtle, but it wasn't moving. I grabbed it to pick it up... and it still wasn't moving. It was dead! :( I'm glad it wasn't run over like the other turtle though... Still, that's so sad! I coulda sworn I saw a head poking out to move when I first passed by it. But then when I turned around and passed it again it definitely hadn't moved. :(
