I saw a recent documentary in the past year that highlighted the fact that there were numerous pedophiles living in the area close to Jon Benet's house. One of these pedophiles supposedly used to sit and watch Jon Benet and other little girls at Ballet practice!

Another group of pedophiles/robbers were known to have broken into homes in the same neighborhood Jon Benet lived in around the time of the murder.

I think there are many other suspects besides the parents.
