Tanner was born and raised in the United States and, at some point, joined the Liberty City Police Department, later becoming an undercover officer. He is later tasked with following Yakuza co-leader Asuka Kasen and becomes her chauffeur.
Events of Grand Theft Auto III
Asuka later discovers Tanner's true allegiance and orders Claude to kill him on the streets of Staunton Island. Asuka leaves a note for Claude, telling him to find Tanner at Kenji's Casino. When Claude eventually arrives at the casino, Tanner is seen jogging down a staircase, rushing towards his car in an attempt to make a getaway. Claude pursues and attacks, which leads to him catching and killing Tanner on the streets.
References to "Driver" Series
Tanner is given a female pedestrian's running animation, an obvious reference to the strange way that Tanner walks in the Driver games.
