How many million-dollar mansions happen to have tables in the yard with broken legs? If you were a millionaire, wouldn't you have something like that repaired or thrown in the trash? I've literally never known anyone to keep a table with a broken leg in the yard because the minute someone set something on it, it would collapse.
Isn't it more likely that someone stood on the table to help hang her from below, and the little dust disturbed above is because she didn't go over the rail - someone disturbed it in putting their hands there and drawing the rope up and over to set it up. The combined weight of RZ and the perp on the table broke it, or she was stood on it and then it was kicked out from under her, perhaps by kicking the leg so the table dropped and so did she.
In addition to this, one thing that disturbs me is what others have mentioned - women don't search Asian *advertiser censored* and find creative, spectacular, visually shocking ways to kill themselves. They'd just take pills. Or just hang themselves inside the garage. Or just gas themselves in the garage. They don't paint odd sayings on the door with no prior history of weird behavior like this. However, men with previous violent pasts do frequently, unfortunately, kill the women in their lives.
