If the family was all that genuinely concerned about finding out who killed them, they would have far more forthcoming with the police in providing cell phone data, etc. and access to the home.

Funny how they didn't do any of that, and bulldozed the home immediately. What did they do instead? Run to the media to complain about the police and propagate unfounded theories that extended family members killed them over money despite their ever-so generous nature.

Let's not forget their own private detective who still came up with diddly squat despite offering rewards for tips.

All of this tells me they exactly what business associates of Barry's had them killed, and will never reveal that to the public because it would tarnish the family's reputation in the public eye.
