I don't know, but I did do some reading into livor mortis as I'd been wondering about that. But I don't really see how that would give a five-day period prior to dumping the body?
I would think that a date would have to correlate with the LE investigation. So, let's say the neighbor described a bruise on Lucas' face on the 11th and that bruise is still visible. It should have dissipated by the 16th/17th.
I was thinking about food and if the last meal is still present and if that correlated to what Lucas was known to have eaten on the 11th instead of what EG claimed she fed Lucas on the 16th.
Aside from that, thinking about LE going back to search the bathroom again, could they have gone back to find shampoo and bubble bath bottles to match the ingredients with the autopsy findings?
