For unknown reasons, the Psycho has a vendetta against the members of the rock band Love Fist, claiming that they "ruined his life". He attempts to assassinate the band members at a signing, so the band sends Tommy Vercetti to the signing in an attempt to draw him out. The Psycho appears disguised as a woman, pulls out a pistol and kills a security guard at the signing before attempting to escape, where he is chased down and seemingly killed by Tommy.
However, the Psycho survives the attack and later leaves a recorded message in the band's limousine, claiming that he planted a bomb which will explode if the vehicle travels too slowly. This results in Tommy driving very fast throughout the city until the band members defuse the bomb. Following this mission, the Psycho is not seen or mentioned again and his later fate is unknown.
