A silver handprint left on the body is often the only evidence found of direct alien contact. Max Evans left a silver handprint on Liz Parker when he healed her. Conversely, Nasedo left a silver handprint on James Atherton and all of Nasedo's subsequent victims. In the pilot, Michael used silver paint to fake the handprint on Maria's body when they attempt to trick Sheriff Valenti into giving up his suspicions about Max.
