He was LBJ's most trusted "wet operations" guy. He killed one man in broad daylight, in front of witnesses. LBJ spent the trial in a nearby hotel, coordinating matters. When the trial ended, Mac Wallace was found guilty of "murder with mallace." The judge sentenced him to five years in prison, and then immediately suspended the sentence.
He's believed to be behind a string of murders, each of which had the property that the removal of the dead person from the condition of being alive helped LBJ in some important way.
It is believed that his fingerprint and palm print were present in the Texas School Book Depository "sniper's nest."
It’s pretty telling that Wallace got off so easy after killing Kinser (who was fooling around with Wallaces wife) in broad daylight with lots of evidence againsst him (5 year sentence which was suspended). His lawyer was LBJs longtime lawyer John Cofer who also represented LBJ when he was elected to the Senate in 1948 amidst charges of voter fraud.
And the beat goes on...
"It is believed". What does that mean? Is there evidence or not? Where is this claim made?
