When I was about 8 or 9 (I'm now 18), I saw a film where a little boy age about two was walking in the desert (it looked like Nevada), and 2 or 3 teenagers rode their bikes off a cliff, and they landed on the kid and killed him. There was a scene later where the boy's father was in a room full of junk and he was crying and cuddling something that might have been his other child, or the body.
I think it may have been to do with raising the dead, similar to Pet Sematary, but I'm not sure about that part.
Does anyone remember what this is?
