Rusty Young is an Australian lawyer who met Thomas McFadden on a tour of San Pedro prison in La Paz. He was so impressed by him that he stayed there (voluntarily) for three months in order to write his story. Following Thomas's release from San Pedro, he and Rusty moved to Colombia (without paying the remainder of the bribe to the judges). They lived together for a year in Bogotá, both working as English teachers while finishing the book. Upon publication of Marching Powder, Thomas returned to London where he was helped by Prisoners Abroad to find a job as a house painter. He subsequently worked as a labourer. Finding London too expensive, he moved to Africa, where he was born. He now works in a hotel and has given up drug trafficking. Rusty continues to live in Bogotá. He is writing a book about Colombian child soldiers.
