Erratic drunkard with a criminal history and a "Jekyll and Hyde" type of personality. Frequented the Silver Screen bar where Alec Pham worked. His unstable personality and impoverished condition eliminated him as a suspect, as the Cannibal was profiled to be both organized and wealthy.

A WWII veteran diagnosed with severe PTSD and schizophrenia, currently working at his parent's butcher shop downtown. His close correspondence with one of the victims, King, and prior criminal record made him of interest to investigators. However, his dependency on his parents renders him unable to commit the clearly organized murders, and in interviews he he showed genuine remorse for his violent past, which is not consistent with the Cannibal's profile.

A famous trumpet player on his hometown tour after spending many years in New York. He exhibits traits typical of a psychopath, such as impulsivity, drug addiction, and a distinct lack of empathy. One of the early theories surrounding the Cannibal was that he was a psychopath. However, the payments to the families of his victims, even postmortum, shows a degree of empathy or obligation not present in psychopaths. In addition to this, Armstrong has no history of violence outside of small barfights, and his unfamiliarity with New Orleans does not match the Cannibal's geographic profile.

Active fugitive with a history of killing in the New Orleans area. His crimes were committed in the process of various robberies, and share a striking resemblance to the firearm execution method used by the Cannibal. However, the Cannibal did not rob any of his victims, instead tending to leave them with money to settle debts he felt he owed.

Brother of Albert Joseph King, a WWII veteran with crippling depressive episodes and alcoholism. His proximity to some of the victims, King via family, and Pham via frequented bars, made him a suspicious character during the investigation. However, King did not have any strong violent tendancies and his difficulty functioning in daily life did not align with the Cannibal's profile of an extremely competent organized criminal.
