Today, law enforcement has an ever-increasing number of tools at their disposal to track, find, and build a criminal case against potential suspects. These tools also help to provide key evidence in many cases.
This was what happened in a recent case against two registered sex offenders in Southern California, according to a recent CNN report.
The two men, Steven Dean Gordon, 45, and Franc Cano, 27, had been convicted of sex crimes involving children. Gordon was convicted in 1992 and Cano in 2007. As registered sex offenders, the men were required to check in with police every 30 days and wear GPS ankle bracelets.
It was these GPS ankle bracelets that police say connected them to the rape and murder of four women.
