Rabbit Tragety

This morning I woke up to a sad story. My brother David said that he found a rabbit sitting near the shade of a tree around our neighbors house. But as my brother got closer he noticed that this rabbit was very different from a normal one. It's neck was very broken and it was barely moving. At first we thought it was dead, but I think that it was just dying. It is just so sad that this animal is suffering and I wish that it could just be put out of its misery. I just hate to see animals in so much pain, and I don't know what to do.
