So until 29 years, I didn't even get to grieve.

When I say grieve, I mean just have a good cry.

My name is Yvonne Pointer.

They said you murdered Gloria.

If you did, would you just let me know

so that I could please put it into the wondering.

I'm Scott Weinberger, investigative journalist and former deputy sheriff.

I'm Anasiga Nikolaazi, former New York City homicide prosecutor and host of investigation

discoveries true conviction.

And this is Anatomy of murder.

Mother knows best. It's a phrase that many believe to be true. Perhaps no one more so than mothers themselves.

When Yvonne Pointe's daughter was murdered in 1984, she knew that eventually she would find her daughter's killer.

It wasn't just a hope or a wish. It was a promise, a vow made in the depths of unimaginable grief and one

she intended to keep no matter how long it took.

As years stretched on with little progress made, Yvonne's vow began to feel impossible.

But a mother's promise and determination is a powerful force, and in this case, it proved

to be unshakable. For today's episode, Yvonne shared her journey of loss, resolve, and the

relentless pursuit of justice for her daughter. Born as one of 10 siblings in Cleveland, Ohio,

family was always a dominant force in Yvonne's life.

I was a product of 10 children and one family, six boys and four girls.

So needless to say, growing up was quite noisy.

It was always loud and it was always disagreements and it was always food cooking on the stove.
