Yup I saw those connections too in Florida. His boss likes to setup businesses in others names, has multiple ventures, likes to keep a low profile himself, has A LOT to lose if anything is uncovered, has the money to setup some type of elaborate operation if he wanted, has connections in and out of town, has a lot of people that "work" for him, stated in his own words that he helped Rhodens with money via jobs. Hope they are looking at the boss.
My personal feelings is the family isn't capable of pulling this off. Someone fairly smart and I just don't see the family as able to pull this off. The boss or something around where they worked needs to be looked at closer. The killer may have been banking of the fact that they would be the last people thought of to do this and that seems to be the case with all the finger pointing at so many in the family and town.
Has it been confirmed that computers were taken? I have heard that but can't verify. If so that to me points to business 100%. I am sure this is just the tip of the iceberg if we can find this info out. Wish we knew more!
