Robert's provided an amazingly accurate picture that force the prosecution's hand in the decision to call the van Dams to the witness stand. Unfortunately, Roberts didn't go far enough in characterizing the van Dam's involvement in the drug trade leading to the third party abduction and execution style murder of Danielle.
What a load of bovine excrement. An execution style murder is a single bullet to the back of the head. There were no visible signs of trauma to the head. Danielle was probably suffocated, but possibly was locked up somewhere and dyed of dehydration (which implies accomplices).
This crime has the MO signature of child abduction/murder, which is usually sexual in nature, but not always. The FBI knows this, the SDPD knows this, John Walsh and Marc Klaas know this.
You don't know jack about the Van Dam's income or family background, speculations as to drug trafficking are specious rumor.
