Guarded Secrets (12x29)

Air date: Aug 22, 2008

When a security guard disappeared from work without a trace, investigators couldn't determine if he left willingly or if foul play was involved. But homicide was confirmed when the body was found 19 months later. Without any substantial evidence or leads the case went cold. 14 years later, a cold case investigator solved the case after finding crucial evidence hidden beneath the victim's sole.
