You should definitely consult an attorney who handles expungements in your state. Frequently, the answer to your question will depend on what exact crime the person was convicted of committing. I have succeeded at expunging convictions in situations where even other attorneys doubted that expungement would be possible. This is important enough to your daughter's future to consult an attorney. You will not get an adequate answer to your question by using a free online service such as this.
No. forget about expungement.
I truly wish you the best.

The previous answer is most likely correct - but to be sure, take a look at RCW 9.94A.640 (link at bottom of this answer). That statute states what the criteria are for having a charge vacated. It sounds like she was convicted of either a "violent offense" or a "crime against persons", either of which would make her ineligible to have the charge vacated. But she should meet with an attorney before she gives up hope.
