Forensic investigation of cannibal Alferd Packer by scanning electron microscopy/energy dispersive spectroscopy.

Scanning electron microscopy combined with energy dispersive spectroscopy (SEM/EDS) was used to find traces of GSR and lead fragments on 127-year-old forensic evidence. Samples were obtained from the clothing of the victim that was kept at the Hinsdale County Museum. Thirty-nine samples of evidence, along with standard soil and elemental samples were examined by the Mesa State College Research Team. Three pieces of lead were found that revealed a close elemental consistency to samples of bullet lead obtained from cannibal Alferd Packer's gun.
