Well, first you need connections. You need new papers: Birth certificate, Social Security card, License for whatever state you are headed to.
Have a friend with a spare body from the morgue. Dress the body in your personal items and remove the teeth. Take the body and drive to a very deserted area. Get a knife cut yourself and get some of your blood into the crevices of the blade. Stab the blade into the corpse pour fire accelerant on the corpse and all over the car. Light your car on fire with the corpse inside.
Lay low for a few weeks, during this time do your best to change your appearance, start your new life somewhere else and try to avoid any applications that will run your social security number, or finger print you.
