Murder on his mind, 48 Hours Mystery.

I now call the case of the State of South Carolina versus Stephen C. Stanko.

Count one, murder, count two, assault and battery with intent to kill.

Count three, criminal sexual conduct in the first degree.

Count four, kidnapping.

Count five, kidnapping.

And count six, armed robbery.

Greg Hembree speculates Laura Ling may have learned what was going on and confronted Stanko, and that's what led to his rampage.
