Modern forensic analysis leads to arrest in murder of traveling salesman John Warren, authorities say

Items that were found discarded behind a Cracker Barrel restaurant in Georgia in 1985 have led to charges against a suspect in an Ohio killing committed at about that time, investigators announced recently.

As told by authorities, the case centering on killed traveling salesman John Warren is among the latest in the US criminal justice system to illustrate how the application of modern forensic testing techniques on evidence collected decades earlier can lead to closure of cold murder cases.
