Which of the following can determine linkage with other cases when providing evidence?

The crime lab report is crucial in determining linkage with other cases because it provides scientific analysis and findings related to the evidence collected at a crime scene. This report typically includes details about the types of physical evidence examined, such as DNA, fingerprints, ballistics, or trace materials. When a crime lab report indicates that certain evidence from one case matches evidence from another case, it can establish a connection between the two incidents and help investigators identify patterns, potential suspects, or series of linked crimes.

For example, if DNA found at multiple crime scenes matches the same individual, that link can significantly advance the investigation by indicating a repeat offender. This not only assists in connecting various cases but also offers a more comprehensive understanding of the crime’s context and how crimes may be interrelated.

While witness testimony, victim statements, and field notes can provide valuable context and information surrounding a particular case, they do not have the same level of forensic authority in establishing concrete linkages as a crime lab report, which relies on scientific methods and empirical data.
