San Jose, Calif., police charged Jaime Placencia, 43, with felony conspiracy and attempted grand theft relating to the March 22 incident when his wife, Anna Ayala claimed she had bitten into the finger.
Ayala, 39, was arrested last month at the couple's Las Vegas home, and remains in Santa Clara County Jail on $500,000 bail, the San Francisco Chronicle said Wednesday.
Placencia will be arraigned Thursday in a San Jose court and is in the same jail as his wife on $450,000 bail.
Police accused Placencia of getting the fingertip from an injured co-worker on Dec. 20.
The mother of the injured co-worker, whose ring finger was sheared off by a truck lift, said her son gave it to Placencia to clear a $50 debt.
