1. Rape

Rape
(The crime of rape in South Africa is
defined by Criminal Law (Sexual Offences and Related Matters) Amendment Act 32 of 2007. It falls under the broad category of sexual offences,
which includes sexual assault, incest, bestiality and flashing, among other
crimes.
·
South
Africa’s legal definition of rape is very broad. The act states that “any
person (‘A’) who unlawfully and intentionally commits an act of sexual
penetration with a complainant (‘B’), without the consent of B, is guilty of
the offence of rape”. This includes the oral, anal or vaginal penetration of a
person with a genital organ, anal or vaginal penetration with any object and
the penetration of a person’s mouth with the genital organs of an animal.
- Sexual offences include rape and a
variety of so-called ‘‘unnatural offences’’ such as sodomy, incest, bestiality
and masochism.
- Of these
rape is the most frequently reported, and the medico-legal investigation of the
victims and assailants forms one of the most frequent and important tasks of
the district surgeon.
- The use of
drugs to induce amnesia and also to suppress the level of consciousness, has
become more popular during the last few years, particularly with so-called ‘‘date rape’’.

General considerations
- The medical examination should
commence as soon
as the complainant (or a representative) has given consent.
·
The examination must be thorough, taking
particular note of even the most trivial of injuries, as well as the mental
state of the victim.
·
The appropriate specimens (eg vaginal
smears, blood, pubic hair) must be routinely taken. It is often only
much later, and usually at the trial, that the relevance of a particular
observation or laboratory result relating to the victim or assailant is
revealed. It is important to bear in mind that bruising may only appear some
hours after the assault.
·
It is equally important to examine the alleged assailant
thoroughly, both with regard to his physical and his mental state.
·
The examining doctor will not
be in a position to say
whether the complainant was raped from the medical findings alone.
·
Although the very nature of
the investigation demands a sympathetic approach, his or her function is
to report objectively
on the observations and to prepare him/ herself adequately to interpret these
during evidence, avoiding at all stages and at all costs prejudgment of the
case.
·
Note that section 335B of the
Criminal Procedure Act 51 of 1977 contains special provisions enabling a magistrate or, in cases of
extreme urgency, even a policeman, to consent to medical examination of a
minor who was probably a victim of a sexual offence. This may
occur where, for example, a parent cannot be traced within a reasonable
time, or unreasonably refuses to consent, or is himself or herself the
suspected offender, or is deceased.
Interpretation of clinical findings
-
Injuries:
· No observable injuries were recorded in
33% of cases;
· Tenderness and abrasions of the
genitals in 37%;
· Genital tears in 25%, and
· Severe genital lacerations with or
without extra-genital traumatic lesions in 5%.
· Seventy-three per cent of the victims
were allegedly assaulted by a single assailant.

General considerations
- Extra-genital injuries
- The absence of signs of injury on the
complainant’s person should not be construed as consent to sexual relations.
- She may have
been overcome by fear,
submitted under threat of harm to her children or partner, or had been heavily
intoxicated.
- In gang rapes, where the
victim is overcome by a number of assailants, or if attacked from the back by a
single person, it may be very
difficult to offer any resistance.
- Furthermore
the victim may be examined shortly after the event, in which case bruising, which may only appear
many hours later, is not evident.
- It is
therefore sometimes indicated that the person must be re-examined 24
hours later.
- Conversely,
although the presence of injuries suggests that force was used to
overcome resistance — and the more extensive they are the more likely this is
to be the case — it should be borne in mind that the injuries may be unrelated to the rape
as such, the allegation of rape being part of a trumped-up charge.
- The occasional bruise, nail scratch
or bite mark is
not infrequently inflicted during over-zealous intercourse with consent.
This includes a so called love-bite.
- It is also important to examine the finger nails
for any foreign material.
- Genital injuries
- In the case
of a marked disproportion
in size between the assailant and the victim (eg when a child was
assaulted) the injuries to the genital organs may be extensive and extend into the abdominal cavity
and rectum.
- If the victim had borne children,
no injuries may be detected in or about the vagina, despite the fact
that force was used to penetrate the vagina.
- The presence
of an intact hymen,
depending on the type of hymen, is not necessarily an indication of virginity.
Neither is it an indication that rape has not taken place.
- On occasion,
rape is associated with other abnormal sexually perverse acts such as
sodomy, fellatio lingua (oral stimulation of the sexual organ) and genital
mutilation.
Laboratory test
results
- The results
concerning injuries related to sexual assault should be evaluated just as
critically as test results from any other type of injury.
- What the
analyst conveys to the reader should be what is read into the report, purely
and simply, namely that from the specimen a certain result was elicited.
In evaluating this finding relative to the subject under review the reader must
determine whether the following was carried out:
. The specimen
submitted for analysis was drawn properly.
. It
was adequately preserved in transit.
. It
was suitably identified.
. It
was not contaminated before or after collection.
. It
was representative of the subject matter under consideration.
In
addition, the method of testing should be known to the reader, and its
accuracy, specificity and the ability to reproduce it, understood.
- Molecular
biology and the use of
DNA analysis
has made it much easier to identify an assailant. In the case of
DNA typing the result can prove beyond any doubt that a single hair,
drop of blood, sperm, minute fragment of tissue, et cetera, is derived from a
particular person.
- This
specificity, which makes it possible to determine a person’s identity almost 100% accurately,
is due to the uniqueness of each individual’s nucleic acid (DNA) structure of
the cell, and hence the many different permutations of each of these characteristics
in any one individual.
General considerations
- Ejaculation may have occurred in the anus or on the
perineal surface.
- Where no
ejaculation has occurred, despite penetration, there may be a considerable
amount of secreted penile (urethral) mucous which the woman may mistake for ejaculate.
- Intense
emotion or depressants such as alcohol or drugs may inhibit ejaculation.
- The presence
of smegma (secretion) below
a free prepuce (foreskin) suggests that the male has not had intercourse for
some days.
- During
sexual intercourse, where there is marked disproportion in the sexual organs,
the male may rupture the frenular
artery, which passes below the head of the penis, and it may bleed profusely.
In intercourse with consent this may be a source of considerable embarrassment
to both parties, and a revelation to a third party.
- In studying
the topic of rape it is important to bear in mind that mere contact, for
example when the penis is placed on the vulva, constitutes penetration.
Penetration, therefore, does not necessarily involve penetration of the hymen.
The following examples should clarify this point:
1. Strips
of hymenal tissue may still be present in women who gave birth vaginally.
2. The
hymen of the non-virginal non-parous (ie not giving birth) woman, depending on
the type of hymen, generally reveals an old rupture at the mid-posterior
position.
3. A
ruptured hymen may be the result of masturbation, and the hymen may bleed
profusely.
4. Non-virginal
women may have intact hymens, particularly of the annular type. Cases have
been reported of prostitutes where this type of hymen revealed no evidence of
having ever ruptured. Spermatozoa may be found in the vagina for as long as
five to ten days after being introduced there. Although motile spermatozoa can
retain their motility for as long as five to ten days after being introduced
into the vagina, this period is reduced to no more than an hour or two in the
majority of cases.
The
absence of sperm in the vagina does not mean that there was no ejaculation into
the vagina. This absence may be the result of a zoospermia (absence of sperm)
in the ejaculate, or the use of a condom.
