His name was George. He had played both sides of the law and at one point had actually claimed to have killed James but was not believed. He was a bushwhaker then after serving time had went straight. It was the Gov. who brought him back in to infiltrate the gang and he did robberies with them. He had shot James but I don't think anyone has proven this, not to my recollection. That was the episode with that Dr Burns.

When George W Shepherd (aka "One-Eyed George) was 15, he enlisted in the army to fight the Mormons. He eventually met and joined up with William Quantrill and his band of renegade Confederates. He was the cousin of Oliver Shepherd. Jesse and Frank James were also part of this troop. He was involved in the Russellville, KY robbery of the Nimrod & Co. Bank, on Mar. 20, 1868l, with his cousin, Oliver, and the James Brothers. He was arrested and served two years in prison. Oliver was killed when a posse followed him to MO, and tried to arrest him. George returned to Missouri after his stint in prison and tried to go straight. He offered to try to catch the James brothers after the bank robbery in Glendale, MO. George held a lot of animosity towards Jesse. There are varying speculations as to what caused the rift. Some believe that it had to do with a woman, some think that it was in retaliation for Jesse James and James Anderson killing Shepherd's nephew, Ike Flannery, and some believe that he blamed James for his incarceration. Shepherd did retaliate against Anderson by slitting his throat after he tracked him to Austin, TX. He did it on the lawn of the State Capitol Building. He escaped back to MO. Whatever the reason, he was extremely vocal about his dislike for James. Shepherd was in Galena, KS and claimed that he had killed Jesse James after gaining James' trust. He alleged that he had a plan with law officials to lead Jesse into a trap during a robbery attempt in Empire, KS. James recognized a guard and fled. Shepherd enlisted the help of some of his mining buddies to help him kill Jesse James and ambush the rest of the gang. Shepherd caught up with the James Gang, and according to his own accounts, rode next to Jesse, and when Jesse looked at him, he shot him in the head and rode off. Hardly anyone believed Shepherd's account. There were numerous reports of people seeing a quite alive Jesse James in Texas and Kansas. No body was ever recovered that confirmed Shepherd's story. George Shepherd eventually died in 1922, at the age of 75.
