Cause of death

Complications of mixed drug toxicity (opiates, zolpidem, benzodiazepines and doxylamine)

AI-generated summary

A 54-year-old woman with a history of PTSD, depression and suicidal ideation died from mixed drug toxicity (opiates, zolpidem, benzodiazepines, doxylamine). She had been accumulating prescribed medications over extended periods despite her brother's concerns about out-of-date medicines. Letters found at the scene indicated she intentionally took a fatal dose and proposed to assist her mother (an 84-year-old nursing home resident with dementia and terminal cancer) to die. Her mother also died, likely from assisted overdose. The case highlights the importance of deprescribing, monitoring medication accumulation in vulnerable populations with psychiatric histories, and taking suicide ideation seriously. Better communication between family, treating clinicians, and aged care facilities regarding medication management and mental health status could have altered outcomes.

FINDING INTO DEATH WITH INQUEST

Form 37 Rule 60(1) Section 67 of the Coroners Act 2008

Inquest into the Death of: DEBORAH KAYE MACDONALD

Delivered On: 28 November 2013

Delivered At: Coroners Court of Victoria Level 11, 222 Exhibition Street, Melbourne

Hearing Dates: 28 November 2013 Findings of: PHILLIP BYRNE Representation:

Police Coronial Support Unit Sgt David Dimsey

I, PHILLIP BYRNE, Coroner, having investigated the death of DEBORAH KAYE MACDONALD

AND having held an inquest in relation to this death on 28 November 2013

at Melbourne

find that the identity of the deceased was DEBORAH KAYE MACDONALD born on 16 October 1956, aged 54 years

and the death occurred between 1 October 2011 and 3 October 2011

at 29 Fraser Street, St Kilda West 3184

from:

1(a) COMPLICATIONS OF MIXED DRUG TOXICITY (OPIATES, ZOLPIDEM,

BENZODIAZEPINES AND DOXYLAMINE)

in the following circumstances:

  1. The related deaths are those of an 84 year old lady and her 54 year old daughter.

  2. The circumstances are truly sad. Mrs Lane who resided in a nursing home was visiting her daughter Ms MacDonald for the weekend.

  3. Mrs Lane was suffering from a number of serious ailments including cancer in respect of

which she was to have surgery on 4 October 2011.

  1. An arrangement was made that Mrs Lane would stay with her daughter for the weekend to watch the AFL grand final and then return to Central Park Aged Care Facility on Monday 3 October 2011.

  2. On Saturday 1 October 2011 Mr Ken MacDonald received a voice message from his sister stating that Mrs Lane had advised her she “wanted to die”. The following day Mr MacDonald spoke with his sister and questioned her about the voice message. Ms MacDonald told him that “out of the blue” Mrs Lane had stated she wanted to die. Mr MacDonald was apparently satisfied that all was well with his mother and sister as they seemed to be having a good time

together watching the football.

  1. At about 7.30pm on Monday 3 October 2011 Mr MacDonald received a phone call from Central Park informing him that Mrs Lane had not returned as planned.

Mr MacDonald and his wife attended at the Fraser Street, St Kilda West address and found his mother and sister in bed; Ms MacDonald unresponsive and Mrs Lane breathing in with what he described as a “rattly manner.” An ambulance was called; paramedics confirmed Ms MacDonald was dead and Mrs Lane in dire condition. Mrs Lane subsequently passed away in

the Alfred Hospital (where she had been palliated) on 5 October 2011 at 2.33pm.

Autopsies were carried out at the Victorian Institute of Forensic Medicine (VIFM) by

Forensic Pathologist Dr Jacqueline Lee who advised cause of death to be:

1(a) complications of mixed drug toxicity (opiates, zolpidem, benzodiazepines

and doxylamine)

Police attended the Fraser Street, St Kilda West residence where they located a large amount of medications including anti depressants. It is clear that Ms MacDonald had been storing much of her prescribed medication. Some twelve months before the deaths. Mr MacDonald had raised with his sister concerns that she was retaining amounts of “out of date”

medications.

Ms MacDonald had been treated for post traumatic stress disorder and depression over many

years and had from time to time expressed suicide ideation.

Mrs Lane was diagnosed with dementia in 2008. That together with other medical issues including a significant deterioration in mobility resulted in her becoming a resident at Central Park Aged Care Facility.

Upon attendance at the Fraser Street, St Kilda West residence police located three envelopes containing handwritten letters. Two of those handwritten letters penned by Ms MacDonald

were addressed to her brother Mr MacDonald.

In one of those poignant letters, Ms MacDonald states that her mother expressed a wish to die and asked her daughter to “help her die” and it would represent “voluntary euthanasia”. The

letter refers to crushing tablets for Mrs Lane to swallow unassisted.

These letters clearly indicated Ms MacDonald intended to take her own life. It also

establishes that she proposed to some extent to assist her mother to die.

In his statement, Mr MacDonald makes reference to a conversation he had with either his mother or sister some seven years before when the issue of assisted suicide was raised. Mr MacDonald says his mother did not agree with the prospect of mother and daughter ending their lives together, his mother stating she wanted to see her first grandchild bom. Mr

MacDonald says that after that conversation the issue was never raised again. He further states that nothing in his sister’s demeanour over the last six months indicated she was contemplating this action.

  1. Leaving aside the issue of whether Mrs Lane’s death was the result of what I will call an assisted suicide, it is clear that Mrs McDonald intentionally took her own life by ingesting a

fatal dose of prescription medicine.
