The white woman called the cops. That pretty much removes her from the suspect list since it's pretty rare for the criminal to call the police.
There was no "suspect list", moron.
The cop had already told the other woman that no crime had been committed.
Whoever calls first is generally considered to be innocent at the moment.
You'd have to be a moron not to know this.
When the cop determines that no crime has been committed, then they're both fucking innocent, moron.
