Some thoughts on the case. Some expanding on earlier discussions.
Assuming there wasn't a prior appointment for the cleaning, the phone destruction, hard drive destruction, and cleaning all occurring will probably make it tough to convince a jury evidence wasn't being destroyed. If the hard drive was actually beat up to disable it, as opposed to it looking in normal shape but just not working, it would suggest evidence being destroyed even more.
So what options are there if that is the case? Someone destroyed the evidence, so if AH wants to avoid time for that he has to pin it on someone else. Anyone who he tries to pin it on, the question would be asked what would be their motive for destroying the phone and hard drive? I can't imagine a story where the answer isn't concealing evidence in the murder.
So implicating someone else in the evidence destruction would pretty much be fingering them as an accomplice in the murder. Let's say the three of them all had a hand in the murder, what would one of them do if he's getting blamed for the evidence destruction? They would probably roll on each other unless there is a payoff of some kind involved. And at that point you might as well have the person take the blame for the murder since you're pretty much making him look guilty over the evidence destruction.
On top of it, there is an aspect I was thinking about with the cleaning service. It could be argued that someone surreptitiously destroyed his phone and the hard drive without AH knowing (whether believed or not by a jury). But the cleaning service people are going to be able to speak to whether AH knew they were coming there, whether he directed them on what should be cleaned, etc.
Again, if the cleaning service was a scheduled appointment, the testimony of those cleaners could really be damning if AH took a personal hand in their hiring and direction once they arrived. If on the other hand it was one of his buddies who took care of it, that might help support any claims that someone else was responsible for the phone and hard drive too and that he had no idea what transpired.
Edit to add: And if AH argues someone else did destroy the phone and hard drive to cover up evidence, that leads to the question, why did AH's phone and security system have evidence of the murder that would need destroying? He'd have to come up with something that has himself not being in control of his phone most likely. And given all three suspects entered the house together around 3:30 am according to witnesses... yeah, I just don't see a very believable story being crafted if they did commit the murder.
The other thing I've been wondering about is one of the rental cars was missing its side mirror and the police were looking for it along the route the car would have taken. That could suggest something particular happening in the timeline of the murder. Perhaps there was a struggle and someone's body hit the mirror and broke it off? Was there an accident involved that led to an altercation? Haven't heard anything more about it. But the cops could probably tell from traffic cameras if it was still on the car when they left the club I should think. The whole thing with the mirror is making me wonder what other physical evidence there might be with the car.
