Given the nature of sexual offences, the case presented to court is often confined to one person’s word against another. Disputed versions of events can sometimes differ in only minor ways. In some sexual offences the timing of an act of sexual intercourse can be a crucial piece of evidence, for example if there was a consensual act with a partner prior to an alleged rape. At Forensic Context we specialise in sexual offences and our experts can provide an opinion about the time range in which sexual intercourse may have taken place, although it is never possible to say exactly when it occurred. We can also assist with whether intercourse is more likely to have occurred at time A rather than time B.
