Victim Targets - Men

Israel Keyes became one of America's most infamous serial killers after carrying out a series of meticulously planned murders across multiple states between 2001 and 2012.

Although he confessed to eight murders, investigators believe the true number of victims may never be known due to his suicide before revealing the full extent of his crimes.

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.

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.
