I agree about the personal relationship motive. Because of the line of succession being so much money and the detailed staging. Only an expert/serial killer with lots of experience would leave such a clean crime scene. Possibly a contracted assassin instructed to not make a mess and leave blood splatter, etc. Bullets can be evidence so the ligature was chosen out of necessity. Also them mirroring their own sculptures makes a mockery of their lifestyle, taste, style and collector status. Seems like a jealous person with a methodical eye and OCD. Someone who enjoys the art of the kill and antagonizing investigators. They didn't take the bodies/evidence of how they were killed. They didn't destroy that evidence. Possibly out of respect for the family and the tradition of a Jewish burial. Took their lives but allowed for bodies to be mourned over and be layed to rest. If the motive was competition in the big pharma world, they probably would've taken the bodies and destroyed all evidence via cremation, dismemberment, sacrifice, torture, etc. Probably didn't drive there because the car would've been seen in surveillance on the block. I imagine them waiting behind a bush in the front yard to follow as they walked in the door or jumped the fence and let themselves in the back. They knew there was an alarm that would probably be set at night so coming in as it was disengaged was clearly thought out. Most intruders come in when people are sleeping to surprise them before they get to their gun safe. But this expert knew their schedule and considered the alarm ahead of time. The pool placement and matching Canadian Tire belts around their necks are curious too. The pool being the most remote place in the house, it would allow for more time to pass before they're discovered by hired help. More time to distance themselves from the scene before TPS discovered the victims. Lights were off but pool lights were on. Probably was plenty of light to stage a crime scene. The fact that their wrists were tied seems like they were threatened with a gun to comply, then strangled and moved downstairs after they were deceased. One by one. I feel like Honey was a liability and was killed as a result of being home before the main target was, Barry. And she could've continued her husband's affairs after he died. Someone wanted control of everything and to punish them for their excess. There's definitely a financial motive and also a lot of revenge. But they gave the family their Jewish burial. Almost like they didn't want to deal with the consequences of their actions and dispose of their crimes. They wanted everyone to see what happens when you're rich and powerful. Not in an antisemitic way but a 'you have too much' and I don't kind of way.
