I saw the posts about ANS's swollen eyes that you and others were posting, and then someone was also talking about morphine sulphate, so looked that up.
It causes swelling of the face! Well, as you posted, lots of drugs do that.
But didn't Perper say or someone said that nothing was found in her stomach? I saw this that the morphine can be given in suppositories.
No wonder HK$ didn't want people in the room when he gave her her "medicine"!
Here's the link about the swelling of the face
Reasons to call healthcare provider immediately
Signs of a life-threatening reaction. These include wheezing; tightness in the chest; fever; itching; bad cough; blue skin color; fits; swelling of face, lips, tongue, or throat.
Too tired or sleepy.
Changes in thinking clearly and logically.
Passing out, fainting, dizziness, or lightheadedness.
Difficult breathing.
Severe nausea or vomiting.
Any rash.
IIRC Mark Hatten claimed he was poisoned with morphine sulfate - woke up in an ice bath.
That may have been one of the discussions that began - suppositories vs. injections vs. pills vs. liquid by mouth.
Of course a morphine dose can be given as a suppository. Ask Marilyn Monroe about nembutol suppositories. Ooops, nevermind...
But was she so out of it that HE administered the final, lethal dose? Did he regularly do this to her and this time the combination with everything else was just too much and it really was just an accident? Who knows.
In any event, IMO it seems to be manslaughter/negligent homicide at the very least for HKS and the doctor(s). Look at this case:
In Florida in the same year, Dr. James Graves was not so lucky, becoming the first U.S. physician to be convicted of manslaughter related to an OxyContin prescription, after local authorities charged that four of his patients fatally overdosed on OxyContin, some of them after combining it with illegal street drugs. Graves contended that his patients would not have died if they had taken the drugs as directed. He is currently serving 63 years.
Interesting article on Dr. Graves (good name for a doctor!):
Morphine is also available in liquid form.
More good information - thanks.
