He has a problem with alcohol and is seen drinking liquor while up at the plate before hitting. He was arrested for attacking an umpire with a baseball during a baseball game after being, in his opinion, unfairly called out after hitting a supposed home run. After assaulting the umpire, he goes to attack the players of the opposing team but is fought off and restrained by his fellow team mates.
While in Oz he was one of the many prisoners to be manipulated by Ryan O'Reily
Prisoner #99M633 Convicted March 16, 1999. Two counts Assault in the first degree. Sentence: 8 years. Up for parole in 5.
Montgomery is approached by Ryan and is paid by him to lie to Leo Glynn about the murder of rapist Patrick Keenan. He is told to say he saw Henry Stanton kill Keenan by attacking him with a barbell, and then stealing his necklace, when actually it was Ryan who did the deed, but had been witnessed by Zahir Arif who had already told the authorities (Ryan knew he had been reported, but not that it was Arif). Montgomery's confession was considered much more detailed than Arif's so Stanton was put in the hole until further evidence could be brought forward; the investigation for the Keenan murder was suspended as neither witness had enough evidence to make the claims superior to the other. This was Ryan's plan all along.
However, Montgomery decided that Ryan had not paid him enough after all, and demanded that he kept paying him otherwise; he'd tell Glynn the truth about Keenan. Ryan agreed to meet up with Montgomery in the prison-library to make a deal about his pay, but instead met up with Stanton in the gym and told him that he had "found out" who had lied about him. When Stanton asked, Ryan initially refused to say, to appear more innocent (and partly to make Stanton angrier), Ryan eventually revealed that it was Martin Montgomery, and a furious Stanton charged to the library, where he found Montgomery waiting, and stabbed him in the neck. While he is in the hospital O'Reily has Keenan's necklace planted in Montgomery's cell, thus framing him for the murder. During season six Stanton says that Montgomery survived, but he "can't sing anymore."
