I'm in the same boat as you man....exact same boat actually. Here is what I've found out.
There are two type of warrants, ones that are worth NY's money to extradite and ones that are not. Certain states have certain rules that deternmine how long they can hold you on the warrant. The farther you go, the better. The longer you stay in school, the better. As for financial aid, as long as its not a federal case, you can still collect full pell, tap, and scholorships. They dont run a background check. So your best bet is to go as far as you can go (thinnk P.H.D.) and take your time. Join the church, all other activities on campus. It'll be your best friend/hiding spot. Besides, "hey I was gone, but I go this degree and did all this good work" better than "I went out and got high and shot someone"
