The Dentist mistake? Maybe they didnt want to get sued...
I'm not sure if I heard this correctly but I thought I heard her sister in law say that Diane went to the dentist about a root canal and then dentist worked on her but she walked out in the middle of it?
If that's true maybe the dentist used something that she was allergic to and she had an allergic reaction to it. The Dentist found out and didn't want to get sued so the Police covered for them saying there was alcohol involved. That autopsy report never sat right with me even when they did it again, it just seems like someone was/is lying and covering their tracks.
They said the kids kept screaming "There's something wrong with Aunt Diane!" and the little boy said "Mommy couldn't see" Could her eye have been closed shut because of the allergic reaction from the dentist?
