Highly doubtful there were two perps capable of abducting a child within 10 miles of each other and within 9 months of each other. That is, of course, unless you think DR kidnapped Jared?
I am not buying that there were 2 people involved. It's like a 40 minute window from boys leaving home until abduction. It was a crime of opportunity. They had never been alone at night before. Also, I feel the perp knew the boys. He disguised himself, and sent boys to run off into the 'woods.' It was pitch black and a dead-end street, only a local would know there were woods there.
I believe this was a fantasy acted out but planned way in advance. DR had the house to himself as his parents were away. Opportunity to act out his fantasy. From the minute he saw those flashlights and was close enough to see who the boys were, he put his plan into action.
In my own opinion, of course.
