Also don't forget the bed sores.
There is no way happy, healthy, dancing MJ would have bed sores.
If you guys don't know how bed sores are acquired; People get bed sores from laying in one position for an extended amount of time, like months.
People who get them aren't able to move around and relive pressure in certain areas, or they don't have anyone to position them every hour.
So a HOSPICE PATIENT (Which is what the paramedic said he mistook MJ for) would be a likely candidate, also someone in a coma. Get the point I'm trying to make. MJ wouldn't have had bed sores, it's just not possible.
So the theory that someone could have died in MJ place is very plausible.
