Jethro is a character in the Grand Theft Auto series, appearing as a minor character in Grand Theft Auto: Vice City and Grand Theft Auto: San Andreas. He was voiced by John Zurhellen, who also voiced Jeremy St. Ives in Grand Theft Auto IV and onward.
At some point in 1986, Jethro has become a skilled machanic, who works on marine engines along side his best friend, Dwaine at the Boatyard in Vice City. The two seemed to be comfortable in Vice City until their business was bought by mob boss Tommy Vercetti. Some time around 1989, the two left Vice City after they could no longer return to the Boatyard, and left of San Andreas, where they found business in San Fierro.
Since Jethro left Vice City, he was originally working at an Xoomer Gas Station in Easter Basin, but later found a new job working on low-riders at Carl Johnson's garage, along with his friend Dwaine.
