Heath Ledger's Last Hours: New Details Emerge

Things do not add up in the MTV/ AP story

The fact that at 12.30 he was supposedly snoring, yet at 3.30 he had been dead long enough for lividity to have been evident.

 Why was CPR and rescussetation attempted even when lividity was present.

Eithewr the houskeeper or the massuese is confused or lying.

This on lividity for Wikipedia The bold italics is my highlighting

Livor mortis or postmortem lividity (Latin: livor—bluish color, mortis—of death), one of the signs of death, is a settling of the blood
in the lower (dependent) portion of the body, causing a purplish red
discoloration of the skin: when the heart is no longer agitating the
blood, heavy red blood cells sink through the serum
by action of gravity. This discoloration does not occur in the areas of
the body that are in contact with the ground or another object, as the capillaries are compressed.

Coroners
can use the presence or absence of livor mortis as a means of
determining an approximate time of death. The presence of livor mortis
is an indication not to start CPR,
or to stop it if it is in progress. It can also be used by forensic
investigators to determine whether or not a body has been moved (for
instance, if the body is found lying face down but the pooling is
present on its back, investigators can determine that the body was
originally positioned face up).

Livor mortis starts 20 minutes to 3 hours after death and is
congealed in the capillaries in 4 to 5 hours. Maximum lividity occurs
within 6-12 hours.
