Sins of the (Grand)father? (Revised)

A 6 year old boy who was abducted 4 days ago is now back safe with his family and police say his grand daddy may be to blame! 4 days ago Cole Puffinburger was abducted from his mothers home by two armed men posing as police officers. The boy was found on a side street by a bus driver near a Methodist church. Law Enforcement Officials have now arrested the boy's grandfather whom they believe stole millions from drug dealers and was supposed to pay it back in ransom demands. While the author of this piece seems rather objective I think the Grandpa should fry! anyone who steals money from drug traffickers is only asking for trouble. What the man should have done is gone to the police and told them about the traffickers instead of stealing from them. Most other news articles are giving sympathy towards the boy, but are just as suspicious of the Grand-dad as I am. My question: How did this grandpa find out about this drug ring in the first place?
