The detectives that put their life's work and their life's blood into this,

this is very, very serious business.

It's not a TV show or a movie.

My job is to protect the community and protect the memory of that victim who cannot speak for herself.

And that means I got to put everything I got into it.

... got into it.

I'm Scott Weinberger,

investigative journalist and former deputy sheriff.

I'm Anasiga Nikolazi,

former New York City homicide prosecutor and host of investigation discoveries

true conviction.

And this is Anatomy of Murph.

In this digital age, our phones have become our constant companions.

And whether it's a blessing or a curse, it also means that rarely are any of us without a camera.

And those cameras, they're always rolling, constantly capturing all of the outrageous, the mundane, the inspiring, and the shocking moments of everyday life.

And if you've ever scrolled social media and watched a supercut of people falling down or a tense

confrontation in a parking lot, you probably know what we're talking about. These days it seems like

our every misstep is just destined to be captured on video and shared with the world. But what happens

when a camera captures something even darker? We've probably all seen the shaky footage of an escalating conflict,

but rarely do we think about the real-life violence that may have followed,

or the very real consequences when a camera may be the only witness to a murder.
