Is fiber USUALLY class or individual evidence?

Fiber is usually considered class evidence because it can be associated with a specific type of material or source, such as clothing or carpet, rather than a specific individual. While certain characteristics of fiber can potentially link it to a particular source, the variability and commonality of fibers make them more useful for establishing connections to broader categories rather than pinpointing an individual. In forensic contexts, fibers can help establish associations but are not definitive proof of identity.
