We all have a place of peace that we try to seek out at the end of a long day of work.

Let me go for a walk, take a dog with us, our best friend, clear our mind, that place of safety, that place of peace suddenly explodes and your life comes to the end.

Somebody's wielding a knife, they're hovering over, they're bearing the knife into your body over and over and over again.

And maybe the last thing you see is your dog dying right before you. That's our case today.

I'm Joseph Scott Morgan and this is Body Bags.

Joining me today is my good friend Jackie Howard, executive producer of Chrome Stories with Nancy Grace. Jackie, what can you tell us about this case?

Catherine Katie Janice took her dog Bowie for a walk in Atlanta's Piedmont Park.

Now Piedmont Park to put this in terms where other people who are not from this area can understand would be like taking a walk in Central Park in New York.

Katie's went to see her girlfriend Emma who was working down the street as a bartender and there were lots of people out walking their own dogs.

This is kind of a typical scene for this Midtown neighborhood. After leaving the bar, Katie continued her walk.

After work, Emma went home, but Katie wasn't there. She should have been, she should have been back from the dog walk by then.

So Emma started calling Katie's cell phone, but did not get an answer. Then she sent text messages.

They also went unanswered and that's when the worry set in and Emma went out to look for Katie.

Obviously when you're walking a dog, you can go anywhere. So Emma used the find my iPhone app on Katie's phone.

It showed Katie's phone was about a hundred yards inside Piedmont Park, which was very close to Katie and Emma's home.

Emma thought maybe Katie had dropped the phone so she went into the park to find it, but what she finds is a very gruesome scene.

The first thing she saw was Bowie. Bowie was dead. That is the dog. And it's a pit bull, not too far away.

Emma found Katie's body and she was dead.

This is a very gruesome crime Joe that we're going to talk about, but let's talk about the beginning.

Bowie and Katie were not found next to each other, but they were found, especially Bowie, at the entrance of the park.

There's so much to talk about here, Joe.

As you know, I worked in Atlanta for a long time and I'm very familiar with Piedmont Park.
