Little is known about Garrett Fowler. He used to work for the Violent Crimes division of the FBI. His wife was killed during a robbery, after which Fowler took a one year leave from the FBI. After his return, Fowler's files were sealed.
Fowler set up Operation Mentor to try to gather information about and take down Peter Burke. Fowler tapped Peter's phones and recorded conversations between Peter and Neal. The object of the operation may have been to find the Music Box.
At the beginning of Season 2, Peter learns Fowler's whereabouts are unknown and OPR denies the existence of Operation Mentor. Also after he was held at gun point by Neal he told Peter and Neal how a Mystery man gave him the name and whereabouts of his wife's murderer. The next day, Fowler got a tape showing what he did to the murderer and he was told he gets the music box and the tape disappears.
