9 Ways to Prove Sexual Assault Without Physical Evidence

Investigators don’t always need forensic evidence to prove a sexual assault occurred.

9 Ways to Prove Sexual Assault Without Physical Evidence

Investigating college sexual assaults is a sensitive process, and to actually prove a sexual assault occurred is an extremely difficult task.

Why can sexual assaults be so difficult to prove or disprove? Unfortunately, there are a number of reasons.

The Department of Justice found that most rape victims don’t tell anyone about the attack, so just getting the victim to make an official report is the first hurdle, and getting them to follow through in the investigation and adjudication phases can also be a challenge.

Additionally, one DHHS study found that more than 50 percent of college sexual assaults involve alcohol, which can affect recall and make the victim fear being punished or feel shame. Another study found that 90 percent of sexual assaults are committed by someone the victim knows, which can lead to confusion on the part of the victim and reluctance to pursue justice.

Witnesses can also be hard to come by in sexual assault cases generally, and in college specifically because of the prevalence of large, unsupervised parties.

But experienced sexual assault investigators can find ways around all of these hurdles, and justice can be brought even in sexual assault cases without much initial evidence.

New Title IX changes relating to the college sexual assault investigation process might mean different campuses are using different standards, but every college still has the same goal of keeping their students safe and comfortable.

Below we give some best practices for campus police to get to the bottom of any sexual assault report, even with limited or no physical evidence. The information is adapted from The Blueprint for University Police: Responding to Campus Sexual Assault, which focuses on giving law enforcement information on handling rape and sexual assault cases.

Searching for Proof During Sexual Assault Investigations

At first, sexual assault reports can appear to be “He said, she said” scenarios where there’s little investigators can do to corroborate the accused or accuser’s stories. Unfortunately, experienced sexual assault investigators are familiar with these scenarios.

There can’t always be forensic evidence to work with, but police can still prove sexual assault occurred or didn’t occur with little to no initial evidence, even in cases where there are no witnesses. Here are nine tips:

  1. Practice interview techniques such as victim debriefing and adapt an “information gathering” versus interrogation approach to suspect interviews to gather information. Understand physical descriptions (e.g. tattoos), smells and sounds the alleged victim remembers. Here’s more facts and myths on sexual assault that police should know.
  2. Document the specific details of the allegations down to condom use.
  3. Gather circumstantial evidence during the investigation, such as a sudden behavior change from the alleged victim. Look for dropped classes, withdrawal from sports or social clubs and a sudden change in academic performance.
  4. Try to establish elements of force, threat or fear if present from either party.
  5. Look for a serial pattern of behavior from the accused by contacting others who may have been victimized by that person, while being careful not to marginalize the accused.
  6. Conduct an extensive investigation for corroborating evidence including social media and cell phones.
  7. Evaluate the need for a search warrant.
  8. Consider the utility of a pretext phone call to gather evidence from the accused.
  9. Identify and contact any outcry witness.

  1. 1. can be difficult to disprove
    the accused doesn’t have to disprove it. until the accuser proves it, he is innocent
    imagine a society where accused have to prove they didnt commit a crime

    2. try to establish elements of force, threat, or fear from either party
    this should be pretty self-explanatory why this isnt supposed to happen

    3.if there was a rape, DNA could easily prove if it happened or not.
    even if they used a condom, it will still show. everywhere you go, everything you do, you leave some type if DNA. hair, skin, etc…
    its not perfect. maybe it was consensual at first but if we start with this, we can figure out if it even happened or not. after it has been determined it DID happen, you now at least know the evidence to determine consent exists somewhere

    4.rape is unwanted PHYSICAL sexual contact. everything else is bullshit
    and yes, some people do IN FACT believe “over the internet rape” is a thing
    the fact that needs to be clarified is kinda sad

    • EDIT:
      *the fact that this needs to be clarified*

        as i read your comment there have been hundreds of women that claimed to have been sexual harassed or assaulted 5 to 20 years ago and have NO PROOF or physical evidence of it and yet the men are being sued and going to jail etc… We live in a society that has allowed women to lie just to get money and has left real women in real life situations that are being beaten and raped for REAL and they can no longer be trusted because we don’t know if it’s real or not… I am a woman and I am disgusted by how many women (ugly women at that) that are lying against rich men just to get money in their pockets. it is sickening

    I believe it is close to impossible for a victim to be able to come forward about their rape after a couple months…definitely after a year

    It’s relieving to know that there are experts out there that can really help your case even if there are no physical pieces of evidence available. I will share this information with a friend of mine to make her feel better since she really feels like she’s going to lose if ever she files a case. From what I know, one of her colleagues is really creeping her out because the actions and the words that he was using on her is already bothering her. Thanks for the information!

    Rape is a horrendous experience and though the police won’t follow any leads the victim will be pursued for years by extortionists. It is a dangerous situation and something should be done to make the government prosecute rapists.

  5. Ada says:
