4.1 INTRODUCTION
When two items come in contact with one another there is a potential for transfer of either substance or pattern. Transfers between items are an important means to infer the occurrence of past events, and as such they become evidence when the past events are of legal concern. Transfer evidence results when, from observations on the separate items, we can infer that a contact between the two items did take place or may have taken place.
