Why did the Boston register dub him as the even Steven killer?

The Boston Register referred to him as the "Even Steven Killer" due to his methodical approach to crime, which involved targeting individuals in a seemingly balanced or fair manner, making his actions appear calculated and even-handed. This nickname highlighted the chilling nature of his crimes, as he chose victims based on a perceived sense of fairness rather than random selection. The moniker also underscored the psychological aspect of his behavior, suggesting a twisted sense of justice or equilibrium in his motives.
