Marta is a a drug mule and friend of Elizabeta Torres that appears in several missions in The Lost and Damned. In the mission Marta Full of Grace Elizabeta sends Johnny to pick up Marta from Francis International Airport who is arriving with a large amount of cocaine hidden in her digestive tract. Unfortunately customs have discovered what Marta is carrying and attempt to detain her. After a shoot out with the police Johnny rescues Marta and takes her to Elizabeta's apartment. Interestingly there seems to be some chemistry between Johnny and Marta, though nothing ever comes of this as Elizabeta (a bisexual) makes it very clear to Johnny that Marta is hers'.
