FBI using pigs to practice fingerprint techniques
Stacia Willson: KENS 5 Eyewitness News
San Antonio's FBI office is turning to the animals to turn up new evidence, and dusting for prints has risen to a whole new level.
"Pig skin is the closest to human skin," forensic examiner M.K. Pritchard said.
"When our ERT teams go out to crime scenes, and they find victims after rapes, murders or anything like that, a deceased individual, we want to see if we can develop latent prints of the suspect on the skin of the individual," Pritchard said.
Agents use glue to adhere to the oils of a fingerprint. After that, a special magnetic dust is spread across the skin.
"It would just be another forensic technique that we could utilize in order to get a suspect in a case," Pritchard said.
