andreww - LE in general saw red flags immediately, LA heard their opinions before she arrived on the scene. After a few hours in the presence of the Rs and their friends, she knew exactly what she was doing. She had a gut instinct and sent the 2 men on a search, knowing that the true perp would 'locate' the body. It was risky but successful, the body was found but of course, the crime scene was destroyed by JR & FW. FW had seen that tape before and JR was now saying it was over her mouth. He went back to the wine cellar to look at that scene a few times. He was gobsmacked that he didn't notice a dead child wrapped in a white blanket laying on the floor in the middle of a quite bare, small space right in front of the door! They want him to think HE is crazy.
LA looked into JR's eyes as he lay JBR onto the floor at the top of the basement stairs and saw something that made her mentally count her bullets. She knows what she saw and it was the face of a person who knew exactly how the child died. She knew instantly that this was a set-up, the cover-up of a familial homicide, ( her specialty was 'women in crises' and she was trained to handle crimes against women and children), her instincts were right, she saw through him in that instant and knew no one would ever be prosecuted, then lost control of the crime scene as everyone and their brother threw blankets, sweatshirts and throws over the body, clung to it, stroked it. Terror and horror for all but the remaining R children.
I don't know if John Douglas talks about perps intentionally contaminating the crime scene, but LA knew LE had all been had and it was already too late to fix it. PR and JR were running a hotel, with guests and LE coming and going all over the house, as the child lay dead in the cellar.
The timing of the finding of the body just happened to coincide nicely with the older children's arrival in Boulder and the whole family, friends to boot, were ushered from the house. NONE of the other children saw what JBR looked like in death. They were all spared. BR was ushered away at 7am, arrangements had to be made for the other kids to land in MI and get a flight out to CO. Just as they arrive - no one can enter the house.
It all started clicking together for LA.
