Some time before Elg's death, Tigre was riding his scooter when he crashed into a car, severely injuring its driver. Unfortunately for him, the driver was Viola Cadaverini, the granddaughter of Bruto Cadaverini, the most powerful criminal in all of Los Angeles. In order to placate Bruto, Tigre needed to acquire $1 million to pay for the surgery needed to save Viola's life.
To this end, he called in the loan of a young computer programmer named Glen Elg, who had racked up a huge debt due to his gambling addiction; with no way to pay off the loan, Elg used his talents to create a devastating computer virus that Tigre could sell on the black market for millions of dollars. On the day in which Elg had agreed to repay the loan, however, Elg managed to catch a lucky break, winning the grand prize of the city's local lottery, more than enough money to pay off his debts, but not nearly enough to take care of Tigre's. A desperate Tigre poisoned Elg and took the CD containing the virus, acting out the murder afterward to provide a false witness for testifying and pinning the blame on Maggey Byrde, who was a waitress at the restaurant in which the murder had taken place. (The owner of the restaurant, also in deep debt to Tigre, was forced to help with the charade.) Finally, in order to clinch his scapegoat, Tigre masqueraded as Phoenix Wright and represented Byrde in court, easily getting her a guilty verdict with his shoddy handling of the case.

One month later, Dick Gumshoe angrily chastised the real Wright for the trial, of which Wright had not previously been informed. Wright took up Byrde's appeal and brought out the true killer in court. In the end, Wright tricked Tigre into implicating himself by presenting a bottle containing Elg's ear medicine and claiming that it was the poison used to kill him; Tigre quickly corrected him, which he would have been unable to do if he was not the killer.
- The name "Furio" derives from "furia", which is Italian for "fury"; his surname is Italian and Spanish for "tiger".
- Tigre is often considered to be the evil counterpart of Phoenix Wright due to his similar appearance. He talks in a Brooklyn accent (example: "youse" instead of "you") and uses italianized terms (example: "dis" instead of "this"). In the Italian translation, he uses the letter "k" liberally throughout his sentences (a letter which does not exist in Italian, implying him to be foreign).
- Prior to finding out his name, Maya Fey refers to Tigre as "Xin Eohp", which is "Phoenix" spelled backwards. She also asks about whether there was a fake Maya named "Ayam", which is "Maya" spelled backwards.
- His character theme music is "Warehouse Tiger".
