Do not confuse the ME, who did autopsy, with the funeral director who may or may not have been the embalmer(?)!
The funeral director made no statement at the time of the funeral but later when asked reportedly said TM’s hands show no marring.
My take is trust the ME who is a certified Medical Doctor not a “Digger O’Dell”!
The autopsy would have been done before it was known this would be a racist shake-down so yeah, I’d definitely trust the coroner’s autopsy more than the funeral director in the middle of the shake-down.
