Does it make it harder on a person that has warrants and has been running for a couple years the longer she waits?

Yes, it can. When someone has warrants, generally the best result comes from securing counsel to assist with presenting one's self to the court rather than showing up. It is also advisable to have a bond person lined up and ready to go. You do not indicate where in OK you have warrants, but you are welcome to contact me for further information even if you are outside central OK.
