Famous Case where Hair/Fiber Analysis was used

One famous case that was solved using hair/fiber analysis was that against Dr. Jeffrey MacDonald, Army captain and Green Beret, who in 1970 was accused of murdering his two children and pregnant wife. He claimed that armed men came into his house and killed them, and then attacked him, but he was able to fend them off. Investigators proved this testimony a lie when the blue fiber that created Dr. MacDonald's clothes were found inside of some of his wounds, which led investigators to imply they were self-inflicted. Also, the same fibers were found under the body of his dead wife, in the room in which his children were killed, and the blue fibers were found under a fingernail of his murdered daughter.
