Some of the serial killers listed here are believed to have murdered even more people than they were convicted of killing. The true death tolls may never be known.
Herb Baumeister was linked to the deaths of 11 men in the early 1990s, and police believe he killed up to 20 others. Eleven bodies were found in his backyard in Indiana, eight of them identified as men who had disappeared after visiting gay bars.
When police issued a warrant for Baumeister’s arrest, he fled to Canada and killed himself with a bullet wound to the head.
