Tonight at 5 PM on NBC12 News

We've reported on the actions of sex offenders for years. But how are they caught? Who keeps them in line? We decided it was worth a trip to find out.

Wednesday, beginning at 5 p.m., we'll have four members of the Virginia State Police Sex Offender Investigative Unit working our Call 12 Center. They'll take your tips on sex offenders living or working where you live. Wednesday at 11pm, we'll show you what happens AFTER the call.

How are these cases investigated? What type of technology is used? Most of all - how do they keep your family safe? We're along for the ride, tonight on NBC 12. -
