Poisoning (strychnine
- arsenic)
Location: Germiston, Gauteng, South Africa
Status:
Executed by hanging
at Pretoria Central Prison on December 30, 1932
The case attracted almost
unprecedented public interest. Queues of spectators lined up for hours
each day before the proceedings began. On the final day of the trial,
some spectators who had waited overnight to ensure a place in the
court sold their seats for up to 30 dollars each!
At that time it was normal for
anyone accused of murder under South African law to be tried by a
judge and jury, although the law allowed them the option of being
tried by a judge and two assessors. Since public opinion weighed so
heavily against Mrs de Melker, she had opted, on the advice of her
legal counsel, for the latter.
The proceedings were opened before
Mr Justice Greenberg and two senior magistrates, Mr J.M.Graham and Mr
A.A. Stanford. Mrs De Melker faced three charges. Firstly that, on or
about 11 January, 1923, and at or near Bertrams, in the district of
Johannesburg, she had murdered her husband, William Alfred Cowle, by
poisoning him with strychnine. Secondly, that on about 6 November,
1927, in the same district, she had murdered her second husband,
Robert Sproat, by poisoning him with strychnine and, thirdly, that on
or about 5 March, 1932, in the district of Germiston, she had murdered
her son, Rhodes Cecil Cowle, by administering him poison, namely
arsenic.
Daisy De Melker (nee Hancorn-Smith)
was born on 1 June, 1886, at Seven Fountains near Grahamstown. She was
one of eleven children. When she was twelve, she went to Bulawayo to
live with her father and two of her brothers.
Three years later, she become a
boarder at the Good Hope Seminary School in Cape Town. She returned to
Rhodesia (now Zimbabwe) in 1903, but apparently found rural life
unexciting, because it was not long before she returned to South
Africa and enrolled at the Berea Nursing Home in Durban.
On one of her holidays in Rhodesia,
she met and fell in love with a young man named Bert Fuller who was a
civil servant in the Native Affairs Department at Broken Hill. They
planned to marry in October, 1907. However, Fuller contracted
black-water fever and died, with Daisy at his bedside, on the very day
they had planned to marry. Fuller left a will bequeathing £100 to his
fiance.
In March 1909, about eighteen months
after the death of Bert Fuller, Daisy Hancorn-Smith married William
Alfred Cowle, a plumber, in Johannesburg. She was 23; he was 36. The
couple had five children, four of whom died. The first were twins, who
died in infancy; their third child died of an abscess on the liver;
and the fourth suffered convulsions and bowel trouble and died at the
age of 15 months. Their last, and only surviving child, Rhodes Cecil,
was born in June 1911.
Early on the morning of 11 January,
1923, William Cowle become ill soon after taking Epsom salts prepared
by his wife. The first doctor who attended him did not consider his
condition serious and prescribed a bromide mixture. But, Cowle's
condition deteriorated rapidly. Not long after the doctor had left, he
took a turn for the worse. His wife summoned the neighbours to help
and called for another doctor.
Cowle was in excruciating pain when
the second doctor arrived. He foamed at the mouth, was blue in the
face, and screamed in agony if anyone touched him until he died. Faced
with these symptoms, the second doctor suspected strychnine poisoning
and refused to sign the death certificate. A postmortem was
subsequently performed by the acting District Surgeon, Dr Fergus. The
cause of death was certified to be chronic nephritis and cerebral
hemorrhage. Daisy Cowle, the sole beneficiary of her husband's will,
inherited £1795.
At the age of thirty-six, and three
years to the day after the death of her first husband, Daisy Cowle
married another plumber. His name was Robert Sproat, and he was ten
years her senior. In October 1927, Robert Sproat became violently ill.
He was in great agony and suffered severe muscle spasms similar to
those experienced by William Cowle. He recovered.
A few weeks later, he suffered a
second fatal attack after drinking some beer in the company of his
wife and stepson, Rhodes. He died on 6 November, 1927. Dr Mallinick,
the attending physician, certified that the cause of death was
arteriosclerosis and cerebral hemorrhage. No autopsy was performed.
Following Robert Sproats death, his widow inherited over £4000, plus a
further £560 paid by his pension fund.
On 21 January, 1931, Daisy Sproat
married for the third time. Her husband was a widower, Sydney Clarence
De Melker, who like her previous two husbands was a plumber. By this
time, Rhodes Cowle was 19. His sister in law, Eileen De Melker thought
him lazy and remarked that he was often unwilling to get up for work
in the morning.
However, another witness at his
mother's trial described him as 'bright and conscientious'. A girl who
met Rhodes at a party a few weeks before his death maintained that he
was a real gentleman. Certainly the evidence conflicted, but none of
it explained why Daisy De Melker decided to kill Rhodes. In the case
of her first two husbands, the motive seemed clearly to be financial
gain. But why kill her son?
Rhodes seems to have been under the
impression that he would come into an inheritance at the age of 21.
Perhaps he was demanding more than she could give him and was becoming
a burden to her? The most obvious answer is that she simply didn't
like him. He was a disappointment to her. She had pampered him all his
life, but he rarely showed her any consideration in return.
Whatever the cause, late in February
1932, Mrs de Melker traveled many kilometers from Germiston to
Turffontein, to obtain a quantity of arsenic from a Chemist there. She
used her former name, Sproat, and claimed that she required the poison
to destroy a sick cat.
Less than a week later, on
Wednesday, 2 March, 1927, Rhodes took ill at work after drinking
coffee from a thermos flask which his mother had prepared for him. A
fellow worker, James Webster, also became violently sick. Webster, who
had drunk very little of the coffee, recovered within a few days, but
Rhodes died at home at midday on the following Saturday. A post-mortem
followed and the cause of death was given as Cerebal malaria. Rhodes
was buried at New Brixton cemetery the following day.
On 1 April, Mrs de Melker received
£100 from Rhodes life insurance policy. But the story does not end
there. By this time, William Sproat, her dead husband's brother, had
become, suspicious. Eventually these suspicions were conveyed to the
authorities.
On 15 April, the police obtained a
court order permitting them to exhume the bodies of Rhodes Cowle,
Robert Sproat and William Cowle. The first body to be removed was that
of Rhodes Cowle. The corpse was found to be in an unusually good state
of preservation - which is characteristic of the presence of arsenic
in large quantities.
Sure enough, the government analyst
was able to isolate traces of arsenic in the viscera, backbone and
hair. Although the bodies of William Cowle and Robert Sproat were
largely decomposed, traces of strychnine were found in the vertebrae
of each man. Their bones also had a pinkish discolouration, suggesting
that the men had taken pink strychnine, which was common at the time.
Traces of arsenic were also found in the hair and fingernails of James
Webster, Rhodes' colleague.
A week later, the police arrested
Mrs de Melker and charged her with the murder of all three men. Public
interest in the De Melker case grew, and the newspapers gave the story
a great deal of coverage. The Turffontein chemist from whom she had
bought the arson that killed her son, recognized De Melker from a
newspaper photograph as being Mrs D.L. Sproat who had signed the
poisons register and went to the police.
The De Melker trial lasted thirty
days. Sixty witnesses were called for the Crown and less than half
this number, for the defense. To present the forensic evidence, the
Crown employed the services of Dr J. M. Watt, an expert toxicologist
and Professor of Pharmacology at the Witwatersrand University. In
summing up, before giving his verdict, the judge pointed out that the
State had been unable to prove conclusively that Cowle and Sproat had
died of strychnine poisoning. 'It does not convince me, nor does it
convict the accused,' he said. On the third count, however, he had
come to the 'inescapable conclusion' that Mrs De Melker had murdered
her son. This was evident because:
(a)Rhodes Cowle had died of arsenic
poisoning;
(b)The coffee flask held traces of
arsenic;
(c)The accused had put the arsenic
into the flask (I can see no escape from the conclusion that the
accused put arsenic into the flask..,') on the Wednesday prior to
Rhodes Cowle's death; and
(d)The defense of suicide was
untenable.
When the judge finally turned to
pass sentence on Mrs De Melker, her face whitened, and for a moment
all the strength seemed to leave her body. 'You have been found guilty
of the murder of your son, Rhodes Cecil Cowle. Do you have anything to
say before 1 pass sentence of death on you?' A hushed silence fell
over the court. 'I am not guilty of poisoning my son.' 'There is only
one sentence 1 can pass,' responded the judge, and, so saying, he
condemned her to death by hanging.
On the morning of 30 December, 1932,
Daisy de Melker was hanged.
De Melker, Daisy Louisa Cowle
Thrice married, South African Daisy
de Melker lost her first two husbands under mysterious circumstances,
but homicide detectives were not prone to stirring up a widow's grief
in the chivalrous 1920s.
It took the death of Daisy's
20-year-old son, Rhodes Cowle, on March 5, 1932, to set tongues
wagging, and de Melker soon found herself behind bars. An autopsy
performed on Rhodes Cowle revealed lethal doses of arsenic in his
system, and a pharmacist in Germiston, a Johannesburg suburb, recalled
selling some of the poison to Daisy. Increasingly suspicious, the
authorities exhumed late husbands William Cowle and Robert Sproat --
deceased in 1923 and 1927, respectively -- with traces of poison
revealed in both corpses.
Confronted with the damning
evidence, Daisy confessed. She had dispatched her husbands for
insurance money, killing off her son when he began to blackmail her,
threatening to tip the police unless she parted with her savings.
Convicted of triple murder in a
speedy trial, Daisy de Melker was hanged in Johannesburg on December
30, 1932.
Michael Newton - An Encyclopedia of
Modern Serial Killers - Hunting Humans
Daisy Louisa C. De Melker (1 June 1886 - 30
December 1932), (née Hancorn-Smith) simply known as Daisy de Melker,
was a trained nurse who poisoned two husbands with strychnine for
their life insurance while living in Germiston in the central
Transvaal (now Gauteng), and then poisoned her only son with arsenic
for reasons which are still unclear. She is historically the second
woman to have been hanged in South Africa.
Daisy de Melker was accused of three murders but
was only convicted of one, that of killing her son. The charges of
poisoning her husbands were never proved in a court of law. It was
William Sproat, the younger brother of her second husband, who
fingered her because he wanted Robert Sproat's will in favour of Daisy
declared invalid. Daisy refused to refund an alleged loan from Mrs
Jane Sproat, Robert's mother, to Robert; she regarded it as a gift and
argued that it was not stipulated in the will as a loan. William
Sproat won the civil case regarding the will, which ran concurrently
with the murder trial, and was awarded costs. Daisy withdrew on the
date Justice Greenberg sentenced her for murder. William's was a
Pyrrhic victory however. To pay her exorbitant legal costs Daisy had
to hock all her assets. She was declared insolvent and was eventually
buried in a prison pauper's grave.
Early Life
Daisy
Hancorn-Smith was born on 1 June 1886, at Seven Fountains near
Grahamstown, South Africa. She was one of eleven children. When she
was twelve, she went to Bulawayo, Rhodesia (now Zimbabwe) to live with

contracted black water fever and died, with Daisy at his bedside, on
the very day they had planned to marry. Fuller left a will bequeathing

In March 1909, about eighteen
months after the death of Bert Fuller, Daisy married William Alfred

was born in June 1911.
First
Murder: William Cowle (first husband)
Early on the morning of 11 January
1923, William Cowle become ill soon after taking Epsom salts prepared
by his wife. The first doctor who attended him did not consider his
condition serious and prescribed a bromide mixture. But, Cowle's
condition deteriorated rapidly. Not long after the doctor had left, he

to be chronic nephritis and cerebral haemorrhage. Daisy Cowle, the
sole beneficiary of her husband's will, inherited £1795.
Second
Murder: Richard Sproat (second husband)
At the age of thirty-six, and three
years to the day after the death of her first husband, Daisy Cowle
married another plumber. His name was Robert Sproat, and he was ten
years her senior. In October 1927, Robert Sproat became violently ill.
He was in great agony and suffered severe muscle spasms similar to
those experienced by William Cowle. He recovered. A few weeks later,
he suffered a second fatal attack after drinking some beer in the

was arteriosclerosis and cerebral haemorrhage. No autopsy was
performed. Following Robert Sproat's death, his widow inherited over
£4000, plus a further £560 paid by his pension fund.
Third
Murder: Rhodes Cecil Cowle (son)
On 21 January 1931, Daisy Sproat
married for the third time. Her husband was a widower, Sydney Clarence
De Melker, who like her previous two husbands, was a plumber.
Late in February 1932, Mrs de
Melker travelled many kilometres from Germiston on the East Rand to
Turffontein, to obtain a quantity of arsenic from a chemist there. She
used her former name, Sproat, and claimed that she required the poison
to destroy a sick cat. Less than a week later, on Wednesday, 2 March
1932, Rhodes took ill at work after drinking coffee from a thermos
flask which his mother had prepared for him. A fellow worker, James
Webster, also become violently sick. Webster, who had drunk very
little of the coffee, recovered within a few days, but Rhodes died at
home at midday on the following Saturday. A postmortem followed and
the cause of death was given as cerebral malaria. Rhodes was buried at
New Brixton cemetery the following day.
On 1 April, Mrs de Melker received
£100 from Rhodes life insurance policy. But the story does not end
there.
Reasoning
behind her son's murder
At the time of his death, Daise de
Melkers only son Rhodes Cowle was 20. His sister in law, Eileen De
Melker thought him lazy and remarked that he was often unwilling to
get up for work in the morning. However, another witness at his
mother's trial described him as 'bright and conscientious'. A girl who
met Rhodes at a party a few weeks before his death maintained that he
was a ‘real gentleman’. Certainly the evidence conflicted, but none of
it explained why Daisy De Melker decided to kill Rhodes. In the case
of her first two husbands, the motive seemed clearly to be financial
gain.
Rhodes seems to have been under the
impression that he would come into an inheritance at the age of 21.
One theory is that he was demanding more than Daisy could give him and
was becoming a burden to her. The most obvious answer is that she
simply didn't like him and that he was a disappointment to her. She
had pampered him all his life, but he rarely showed her any
consideration in return.
Arrest,
Trial and Execution
By this time, William Sproat, Daisy
de Melker's second dead husband's brother, had become suspicious and
these suspicions were conveyed to the authorities. On 15 April 1932,
the police obtained a court order permitting them to exhume the bodies
of Rhodes Cowle, Robert Sproat and William Cowle.
The first body to be removed was
that of Rhodes Cowle. The corpse was found to be in an unusually good
state of preservation - which is characteristic of the presence of

able to isolate traces of arsenic in the viscera, backbone and hair.
Although the bodies of William Cowle and Robert Sproat were largely
decomposed, traces of strychnine were found in the vertebrae of each
man. Their bones also had a pinkish discolouration, suggesting that
the men had taken pink strychnine, which was common at the time.
Traces of arsenic were also found
in the hair and fingernails of James Webster, Rhodes' colleague who
had survived.
A week later, the police arrested
Mrs de Melker and charged her with the murder of all three men. Public
interest in the De Melker case grew, and the newspapers gave the story
a great deal of coverage. The Turffontein chemist from whom she had
bought the arson that killed her son, recognized De Melker from a
newspaper photograph as being Mrs D.L. Sproat, who had signed
the poisons register, and went to the police.
The De Melker trial lasted thirty

untenable
When the judge finally turned to
pass sentence on Mrs De Melker, her face whitened but she still
proclaimed her innocence.
Daisy de Melker was condemned to
death by hanging. The sentence was carried out and on the morning of
30 December 1932, Daisy de Melker (aged 46 years) was hanged at
Pretoria Central Prison.
Daisy de Melker in Popular
Culture
De Melker has become somewhat of a
South African icon, and has entered popular myth. If a door blew shut
in the wind they would say “it was the ghost of Daisy de Melker”. If a
child’s hair was unkempt and wild, they said “you look like Daisy de
Melker”.
Rumour (fuelled by tourism
operators no doubt!) has it that De Melker's spirit haunts Ward 7 of
the Transvaal Children's Hospital (now the Florence Transition Home)
in Braamfontein. It is here that she worked as a nurse and learnt
about poisons.
In 1993 a television mini-series
was made about Daisy de Melker, with Susan Coetzer in the title role.
In September 2005 a drag musical
Daisy's Well Hung starring Robert Coleman as "Daisy" was staged at
the Women’s Jail on Constitution Hill in Johannesburg (where De Melker
was imprisoned prior to being hanged). This show attempted to
transform the dour figure of De Melker into a poltergeist of a
husband-killing femme fatale.

SOUTH AFRICA'S MOST FAMOUS POISONER
DAISY DE MELKER: 1932
On 17 October, 1932, at Johannesburg High Court, there began the
trial of Daisy Louisa de Melker, who was charged with the murder of
two husbands and her twenty year-old son, Rhodes. The case attracted
almost unprecedented public interest. Queues of spectators lined up
for hours each day before the proceedings began. On the final day of

Strychnine
Strychnine is a colourless, crystalline powder with an
exceptionally bitter taste. It is obtained from Strychos nux vomica
and other plants. About one and a half grains (100 Milligrams)
constitutes a fatal dose. Although 15 mg of the poison has proved
fatal, and toxic symptoms can result from a dose as small as 5 mg.
Strychnine poisoning causes the muscles of the back to go into
spasms, causing convulsions so intense that the body aches
violently. This symptom called opisthotonus, can last up to two
minutes, during which time the victim is conscious and in extreme
pain. Sometimes the muscles of the face are drawn up in a horrifying
smile of death referred to as the risus sardonicus in some older
textbooks. Eventually these muscles tensions prevent the lungs from
working. Death, from either respiratory failure or exhaustion,
usually follows within an hour.
In the past strychnine has been used as rat poison. At one time,
there was also a plethora of strychnine-based 'tonics' available.
These were usually prescribed to invalids and people recovering from
long illnesses. Tiny amounts of the drug have the effect of raising
the blood pressure slightly, which tends to create a general feeling
of well being. Not surprisingly, accidental deaths and suicides from
strychnine were fairly common. These would result if the bottle had
not been shaken properly and the patient would take a dose of the
concentrated strychnine liquid, which had accumulated at the bottom
of the bottle.
