Can class evidence be use to link a suspect with certainty to victim or crime?

Class evidence cannot link a suspect to a victim or crime with absolute certainty, as it only indicates a common characteristic shared among a group rather than a unique connection. For example, fibers, soil, or shoe prints may match a suspect's belongings but can also match many other sources. While class evidence can help narrow down potential suspects, it lacks the specificity needed for definitive identification. To establish a stronger link, individual evidence or corroborating evidence is typically required.
