Mob hit? Maybe where everything didn’t go quite as planned?
Savvas was CEO of American Iron Works - their website shows lots of big construction projects in the northeast. It might be mob related. Or, someone knowing how rich he was trying to rob them.
One would think they would have plenty of security cameras, etc. I wonder how many security cameras images are sent real-time to off-site storage? Obviously if it is recording inside the house it would have been destroyed.
