Wasn't there a neighbour who said they saw lights on in the house and people moving about? I'm pretty sure I read that somewhere. Also, a family member was allowed to remove items afterwards. Tapes/evidence/etc?
There were several reports from neighbors of various things that night.
You are correct that a neighbor reported "strange, moving lights" (i.e someone walking with a flashlight) in the R kitchen around midnight. The flashlight was found on a counter in a dining area off the kitchen.
A neighbor reported that the Rs sunroom light was ALWAYS on all night every night. But THAT night it was off and the neighbor thought it odd. (Lights turned off so no one who might look in could see WHO was walking with that flashlight?)
Another neighbor reported hearing a horrible child's scream around midnight. She woke her husband, who heard "metal scraping concrete". There were metal paint cans on the concrete floor of the wineceller. Later, not wanting to "get involved", she said maybe it was "negative energy" emanating from JB" instead of a scream. (did the defense lawyers get to her?) Then, she MOVED AWAY, wanting to get away from Boulder and the neighborhood. Later, she again said that it was most definitely a scream.
Police conducted tests from the area outside the wineceller in the R basement. There were vent pipes there to the outside, and lets not forget the broken window. They stood in front of the house of the neighbor who heard the scream and found that a scream COULD, in fact, be heard there, as well as being heard upstairs in the Rs third-floor bedroom.
One of the reasons the neighbor said she did not call police after hearing the scream is because it was so loud (waking her up- she said she slept with her bedroom window open) that she felt the parents of the screaming child must have heard it, and she did not wish to get involved.
Another neighbor, the late Joe Barnhill, reported seeing JR's older son JAR walking into the house earlier that day. He was an elderly man, and friend of the Rs. He and his wife were watching the Rs bichon dog, Jacques, while the Rs were going to be out of town. He used to keep the dog often.
After what was probably "pressure", Barnill said that he "wasn't sure" if it was JAR. As the Rs had no other son that age, and as JAR's friends wouldn't be likely to come there without JAR being there, I don't see who else it could have been.
