Rosa shows us pictures of Yolanda where she appears happy, smiling, holding her babies.

In one photo, a large tattoo of a jaguar is visible on Yolanda's chest.

Rosa tells us after she got Yolanda involved in this case, their relationship was never the same.

According to Rosa, the baby boy's father wanted to marry Yolanda, but he wanted her to get sober first.

By then, Yolanda had developed a debilitating dependence on heroin.

To get by, Yolanda sometimes worked at a strip club in Birmingham's West End.

She was also arrested several times for theft and writing bad checks.

But she wasn't sent to rehab or sentenced to prison for these charges.

Instead, Yolanda leveraged the one relationship where she felt she had some value, the police.

They gave her money.

They would come by the apartment and give her money.

So eventually, I ran across one that had come to the apartment one time, and I had told them that they needed to take care of my daughter.

And they said that they would.

Rosa says that police were knowingly supporting Yolanda's addiction with no regard for her health or the incredible risks she was taking in forming on drug dealers.

My producer Mara spoke with Rosa over the phone about this.

Rosa connects us with an old friend of Yolanda's named Alicia.

Who confirms that Yolanda worked as an informant.

Yolanda would sometimes crash at Alicia's house before walking to the corner where officers would pick her up.

Alicia tells us it wasn't a secret that Yolanda was informing.

Some people even called her.
