Marvin Doyle

Marvin Doyle was a vigilante serial killer who appears in season one of Criminal Minds.

Background
Marvin Doyle had worked as a court reporter in New York City's courtroom 104. His parents had both recently been shot and killed during an attempted robbery. He had been present at the trials of numerous criminals who were acquitted of their crimes for various reasons. Marvin took it upon himself to punish them.

Season One
Marvin is first seen murdering cab driver Walter Durben. After also murdering Rachel Holman, the BAU theorizes that that moth of the murders were premeditated and begin to investigate any link between the victims. Morgan suggests they are looking for a "serial killer groupie"; that is, a copycat recreating the crimes of different serial killers.

It is later discovered that Marvin Doyle was a court reporter who was present at the trials of all of his victims. The team tracks down the court records of all the cases involving the victims, and find him to be the only common denominator. Doyle is then tracked down when he attempts to murder Ted Elmore. Ted is saved by Hotch, who shoots Doyle.

Profile
Marvin was a vigilante whose murders have characteristics of both organized and unorganized killers. He uses a blitz attack (a gunshot), but brings a murder kit with him, notably a number of blindfolds. The blindfolds are meant to make the victim resemble the statue of lady justice, who stands blindfolded with her sword pointed in the air.

Modus Operandi
As mentioned above, Marvin always shot his victims, then stabbed them with a homemade shank (or shiv). He then blindfolds them.
