Classification - Serial Killer

Richard Beasley became known as the “Craigslist Serial Killer” after orchestrating a series of murders involving fake job advertisements posted online in Ohio during 2011. Prosecutors alleged Beasley used Craigslist employment listings to lure financially vulnerable men to isolated rural locations where they were robbed, shot, and buried in shallow graves. The case generated national attention because it exposed how online classified platforms could be exploited by violent offenders targeting strangers. Investigators later connected Beasley to multiple killings and attempted murders linked to the fake employment scheme. The horrifying combination of internet deception, execution-style murders, and burial sites hidden in wooded areas made the case one of the most infamous online predator serial killer investigations in modern American criminal history.
