Evidence is relevant if it

has a logical connection to the fact at issue and tends to make it more or less probable. In other words, evidence is relevant if it has the ability to help prove or disprove a fact that is important to the case. For example, a witness testimony about what they saw or heard at the scene of a crime is relevant evidence because it can help establish what happened. Similarly, physical evidence like fingerprints or DNA samples can be relevant if they help identify a suspect or link them to the crime.
