Over a three-year period in the late Soviet era, Storozhenko carried out a series of attacks on women and girls in and around Smolensk, thirteen of which ended in murder. His position as a police informant — actively participating in the search for the very killer he was — allowed him to operate with a degree of cover that prolonged the investigation and led to four innocent men being arrested in his place. The case is also notable for the investigative work of Issa Kostoyev, who would go on to lead the pursuit of Andrei Chikatilo.

Operating out of Sinaloa in the late 1960s, Avilés Pérez helped establish the organizational and logistical foundations that would define Mexican drug trafficking for generations. His use of aircraft to move marijuana across the border into the United States represented a significant tactical innovation, raising the scale and sophistication of smuggling operations beyond what had come before. He is remembered less as an isolated criminal than as a structural forerunner — one whose methods and networks seeded what would eventually become the Sinaloa Cartel.
