Sexual Assault: What are the Defenses?

“He raped me” does not always hold up. Was there a sexual assault?

A sexual assault nurse examination described in part one of this blog cannot determine these points:

  • Was there consent? Consent is a legal term determined by the trier of fact based on the totality of the evidence presented.
  • Was this vigorous sex or forceful sex? But research suggests multiple anogenital injuries and certain types of injuries are more likely to be identified in persons who report sexual assault.

A posterior fourchette laceration is indicative of penetrating trauma, but no consent.

Redness is considered a non-specific finding as it may result from either medical conditions or traumatic events.

The prosecution would then argue these findings are consistent with and support the allegations of sexual assault.

The defense would emphasize the fact that injuries such as these can occur with consensual intercourse and their presence cannot be directly linked to the person or nature of trauma (intentional, accidental, self-inflicted) applied.

Documentation of a lesion or abrasion on the labia minora finding is vague and ambiguous. An abrasion results from blunt force trauma, whereas lesions result from medical conditions. This finding is of little use to the jury as it cannot be differentiated from medical or traumatic means.

Furthermore, if the examining SANE is not able to discern the difference, how can one expect a jury of non-medical persons to do so? There is room to question the validity of the finding to the labia minora, which could lead the defense attorney to argue exclusion of this or all findings from being presented to the jury.

The prosecution, on the other hand, may need to develop a strategy to mitigate the potential negative impact of this finding.

Sloppy Procedures Harm the Defense

Suppose the victim consented to photography, but no photographs were provided. The LNC told the attorney the facility’s SANE procedures do not include photography, and the facility lacked written SANE policies & procedures.

Suppose the SANE evidence kit was sealed with evidence tape approximately 12 hours after the completion of the examination. When questioned by the attorney about the time lapse, the examining SANE indicated all kits are reviewed by the SANE Manager prior to sealing and supplying the evidence to law enforcement.

These kinds of stumbling blocks complicate a case:

  • Lack of a written SANE exam policy
  • Extended lapse of time between the examination and evidence sealing.

These findings call into question the quality of care, evidence collection and handling procedures, and employment of evidence-based practices as indicated in higher authority recommendations and standards.

The prosecution needs to demonstrate the SANE examination was conducted within the current evidence-based standards and the time lapse was of no consequence to evidence integrity and validity.

Defense of sexual assault

The defense may argue the SANE examination was not performed in compliance with the current standards and the evidence was vulnerable to contamination or tampering and should be excluded. If the SANE examination and evidence is excluded, the DNA results may be excluded as well, which could significantly encumber the prosecution’s case.
