Goodness, get over Partridge already! He is NOT Red John.
The man is dead. Think it
through.

For him to be alive, everyone on the scene of the crime must
have an IQ of a gold fish, the exact EMT to arrive at the scene must be
his minions, the exact doctor that received his body at the hospital
must be a minion, the exact coroner performing the autopsy must be a
minion, his next of kin must be involved with the scam (or if he is
without relatives, he would be sent for cremation, which means the
morgue attendants and funeral house workers must be his minions).

Do you all realize now how crazy that would be?
