And who's next? I mean, that was our big fear. You know, by the time we observed the autopsies, we were very frightened that this individual, whoever it was, would continue killing people. I'm Scott Weinberger, investigative journalist and former deputy sheriff.

And this is Anatomy of Murph.

Whether you're in a small town or a big city, a homicide investigation can demand an enormous

amount of resources, personnel, and hundreds, sometimes thousands of hours.

The exception being when those homicides might be connected, when evidence suggests that multiple

murders may have been committed by just one killer.

It's an efficiency no department wishes for, but when two investigations merge into one,

it can pay dividends in resources and, of course, in the hunt for justice.

Domestic violence unit, criminal unit, the gang unit, theft unit.
