"Accidental Overdose"

Not when you've got this in your system:

"Kennedy Hill had acute methadone, diazepam, nordiazepam, fluoxetine, norfluoxetine and ethanol toxicity in her system at the time of death, according to the toxicology results revealed in the death certificate."

But of course they're Catholic.... 

Perhaps it's time to take a look at a very cosseted family in terms of how she could have been helped, should have been helped.  I fear their past experience with familial mental illness is too much sheltering.
