You pretty much have to assume that every park has its resident perp on the lookout for small children, just as you see the occasional hawk sitting on power poles along the road waiting for roadkill.
That being said, I think its possible that perps cruise in cars looking for the occasional wandering child in the middle of the night - is this what happened to Danielle?
Sad fact.
A 4yr old girl at a park that isn't apparently being watched closely has got to be the sick bastards dream come true.....he didn't even run with her..they walked out of the park.
Praying for her safe return and for her family...it doesn't look good.
