Obtaining fingerprints of a dead person can provide important evidence in a murder case or other investigation, but it can be a tough task after rigor mortis sets in on the body. The typical way of collecting fingerprints -- a special ink used to obtain prints from living people -- doesn't work so well on mummified fingers. However, using black fingerprint powder most commonly used to collect latent fingerprints at a crime scene is a fairly simple way around that problem.
Sprinkle powder on the fingers of the corpse and brush off excess powder with the camel hair brush.
Take a piece of tape and press the sticky side against the finger; apply pressure first in the center and then work out from there.
Remove the tape from the finger.
Stick the tape flat against the index card to get a clean, legible fingerprint.
