Twelve years later, he was hired to build another bomb, as part of a scheme by Dale Biederbeck, and plant it in the back of a car meant to be ridden by the Governor of California and his wife during his hometown's bicentennial parade. Unknown to him, Nunn is also a pawn in a related scheme to frame Monk for murder and incapacitate Monk. In "Monk Takes Manhatten", Warrick Tennyson tells Monk that he was hired to build the bomb which killed Trudy, by a six-fingered man. This six-fingered man detonated the bomb from a distance with a cellular phone.
