He showed us how quickly he took pictures.

Three pictures.

I only had three pictures left in my camera.

Within minutes, both Donna and the man were rushed to the hospital.

I just knew that she was in dire straits.

And Mark Winger began telling police what happened that day.

And I was like, oh, my God.

You know, I said, Donna, oh, my God.

I've been in crime scene work a long time, and there's been very few as severe and bloody as this one was.

Homicide detective Charlie Cox knew there was little hope that either Donna Winger or the man lying near her on the floor would survive their wounds.

I said a prayer.

I do that at all my homicides.

I stand over the body and... Say a little prayer.

Cox grabbed the man's ID from his wallet and then he got right to work, questioning Mark Winger in the bedroom.

I was in shock.

I was in shock the whole time they were questioning me.

I did my best.

And he's more or less rocking back and forth as he's talking to us.

And you can tell he's nervous and upset.

So I'm trying to be as delicate as I can with my questions.
