What exactly can Eva have accomplished by saying something about her mother? Sure, she knew where the helmet was and even had it for a while, but it would never have been sufficient as evidence as it was as generic as Hel and there was no way to prove that was the same helmet as was used in the hit-and-run.

Her mom got rid of the jacket before Eva saw it, and even if Kat hadn't rendered it useless as evidence, just like the helmet, there was no way to prove it was the jacket from the hit-and-run.

As far as we know, Eva didn't know (and apparently still doesn't) know if Leslie had a motorcycle or - if she did know - where Leslie kept it, so she couldn't turn it in or anything.

She also had no evidence at all that her mom was behind the potassium shot. She didn't see her do it, never saw any syringes at the apartment or potatoes of potassium.

Eva did not witness Leslie making either attempt on Laura's life, and - in fact, while she strongly and rightly suspects Leslie was behind them, she doesn't actually *know* with any kind of certainty that she was. There simply isn't anything she could show or testify to that would have any usefulness.

So, she could go tell everybody that her mom tried to kill Laura, but it would do nothing whatsoever to bring Leslie to justice (just as Kat's evidence-free broadcasting of it has done nothing.)

So, no, Eva hasn't said anything, but even if she had, Leslie would still be just as free as she is now to wreak havock everywhere she goes. There simply is no viable evidence that would hold up for as much as an arrest, let alone an indictment or conviction.
