On this date in 1939, Bolivian serial killer Ramiro Artieda was executed at the prison of Cochabamba.
Artieda (German Wikipedia entry) cut his teeth in the murder business at the tender age of 18 by offing his brother Luis in order to become the sole claimant of the family inheritance. In so doing he lost his girlfriend, who was more alarmed by the fratricide — evidence to charge him never equaled the heavy suspicion against him — than she was acquisitive for his newfound loot.
After a brief spell in the United States, Artieda returned with acting experience and a festering grudge against the ex, both of which would come in handy for his new career in homicide. A series of 18ish girls with a resemblance to his former flame suddenly started turning up dead … strangled by a dark-haired charmer luring them to deadly seclusion by posing as a variety of different characters (university professor, trade delegate, monk). His last would-be victim managed to escape him, and then identify him, in May of 1939; eight weeks later, having owned the slaughter of seven young women plus Luis Artieda, he stood in front of a firing squad.
