There is a chance that you would be arrested. Unfortunately, I cannot be any more definite. A Seattle criminal defense attorney may be able to tell you more, but maybe not. You may not be able to answer this question except by flying to Seattle. Some of the answer may also have to do with how common your name is. Sorry, I cannot be any more certain.
If you are facing a felony, you are going to need a lawyer in Seattle. I suggest that you consider hiring someone now to help you with this question and with the underlying felony.
It depends upon how diligent law enforcement at the airport is when you arrive. Before you fly to Seattle, you should hire a Seattle lawyer to help you handle this matter. If you are stopped for any reason in NC, including a minor traffic violation, you could be arrested on the Washington warrant if the police there have put it into the national system.
The attorney responding is licensed only in the state of North Carolina. This response does NOT constitute legal advice and does NOT create an attorney/ client relationship! Rather, the response is in the form of legal education and is intended to provide general information about the matter in question. Although a response is provided to the specific question, there may be other facts and law relevant to the issue that the questioner has left out and which would make the reply unsuitable. Therefore, the questioner should not base any decision on the answer, but should confer with an attorney in person about the specifics of his or her case.
