I'm going to be a little city police department.

Let me help you.

I just got home and the door was open and I walk in and I think she had my girlfriend's been shot.

Where was you shot at? It looked like the hit.

Did you see who did it?

I don't know, I can't go in there.

This victim resided at an apartment inside the building.

Uniform officers had already been there.

The first thing we do is we're going to go in and we're going to see where our victim is.

My name is Mark Beondelino.

I'm a retired homicide detective from the city of St. Louis.

And I investigated the murder of Jocelyn Peters from March 24, 2016.

This isn't someone who would accidentally leave a door open.

She was responsible, one of the most responsible people.

I knew it just didn't make sense.

She was a strong force, fierce advocate for children, loved them dearly, and everyone was going to succeed in her classroom.

She always wanted to do the next best thing.

In her free time, she was always checking out what she could do differently to meet the kids' needs.

What programs there were out there.

There are only three to four full-time arts teachers at the middle school level.

She'd bust into my office, Hey, I need you to come to my classroom today.

I've got some magic going on, and you need to come and see it.
