Operating in St. Petersburg over a roughly two-year span, Voronenko targeted girls and young women, committing four murders before his capture. The killings drew enough public and investigative attention to earn him a designating epithet, a marker of how the crimes registered in the city's collective awareness.

What distinguishes Bonnet from most of his contemporaries is the social position he abandoned — a landed gentleman who took up piracy not out of poverty or desperation, but by apparent choice, purchasing his own vessel rather than seizing one. His brief career along the American East Coast involved the capture of numerous merchant ships, though his inexperience at sea left him dependent on Blackbeard for effective command. He was eventually captured, tried, and hanged at Charleston in 1718, his unusual background making him a curiosity to the public and press of his era.

A longtime associate and close friend of John Gotti, Ruggiero's compulsive phone use became a liability that reverberated through the upper ranks of the Gambino family — FBI wiretaps on his line captured conversations that implicated figures well above his station. His role as caporegime placed him at the operational center of one of New York's most powerful organized crime families during a period of intense federal scrutiny.

Evonitz operated in suburban Virginia communities during the late 1990s, abducting and killing three teenage girls before his crimes were identified — a gap that allowed him to continue undetected for years. The case took a turn when a survivor, Kara Robinson, escaped captivity and provided enough detail to link him to the earlier murders, at which point he fled and died by suicide before facing prosecution. Investigators subsequently suspected him in additional unsolved cases, with confessions made to a family member in his final hours expanding the picture of his activities beyond the confirmed record.

His trajectory from socialist journalist to architect of Italian fascism traces one of the twentieth century's most consequential political reinventions. The movement he founded in 1919 became a template for authoritarian nationalist politics across Europe, and his two decades in power reshaped Italy through suppression of political opposition, imperial warfare in Africa and the Balkans, and eventual alliance with Nazi Germany. The machinery of the fascist state — the party apparatus, the cult of leadership, the subordination of institutions to ideological ends — drew on his particular skill at channeling postwar disillusionment into mass political energy.
