Go to the library and study about the country you want to run to. I would pick someplace with a coast. Don't use your home computer or phone, you don't want anyone to find these searches.
Go buy a cheap laptop from a pawnshop and get a small Linux distro like Puppy or Tiny Core. Load Tor and find yourself a dark market. Buy a new identity. When your transaction is complete trash the laptop burn the USB stick you ran your Linux distro off of.
Buy a boat. Post all over social media about your boat and how you love sailing or fishing or whatever you do in your boat.
This is the hard part, go on a boat trip and at some point call in an emergency then abandon the boat. Make it look good drag out all the life vests and or sink the boat. Swim/row to shore and never ever ever ever go back to your old life.
You could do it for about $30k.
This was my grandma man. She died at 98 smoking until the very end. She used to drive a 1972 Lincon Continental I would ride in the back seat with no chair or seat belt as she chain-smoked filterless Camels and spit dip into a Styrofoam coffee cup.
Edit: I called Camels "cowboy killers" but those were Marlboros and that's what my mom smoked. Grandma didn't dig filters because "that's how you get cancer."
