The item that indicates direct contact with a suspect is offender DNA. DNA evidence is unique to each individual (with the exception of identical twins) and can be transferred during interactions between a victim and a suspect. This biological material, which can include blood, saliva, or skin cells, provides a strong connection that indicates the suspect was physically present with the victim.

In criminal investigations, the presence of offender DNA can be a pivotal piece of evidence that not only implies contact but can also be used to implicate a suspect in the crime, especially if the DNA is matched to a known individual in a database. This connection is direct and scientifically validated, making it crucial for investigations involving personal crimes.

While trace evidence and a victim's clothing can provide valuable information about an incident and can link a suspect to the scene, they may not always indicate direct contact with the individual. Surveillance video can offer visual evidence of a suspect's presence but does not demonstrate physical interaction in the same way that DNA does.
