- "Our source in the police has informed us that one of our drivers is a strangely animated undercover cop! He's more or less useless out of his car, so we've tagged it with a tracer. Make him bleed!"
- ―Asuka Kasen about Tanner.
Tanner is an undercover police officer with the Liberty City Police Department. He is not voiced during his appearance.
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 GTA III
Asuka later discovers this and hires Claude to kill him on the streets of Staunton Island. Asuka leaves a note for Claude and tells Claude to find Tanner at Kenji's Casino. When Claude arrives at the casino, Tanner sees him, rushes to his car and tries to escape, but Claude manages to kill him.
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.
