10. Joseph Albert Oberhansley
Joseph met the bare minimum definition to be classified as a serial killer, having committed two murders. The first was his girlfriend, whom he killed after flying into a rage from meth abuse. He also shot his mother and sister, who both lived, and then shot himself, but failed to die. He was sentenced to prison and then released 12 years later on parole, where he promptly set about finding his next victim, Tammy Jo Blanton, his new girlfriend. When she learned about his past and broke up with him, he murdered her and ate part of her brain raw while cooking and consuming her heart.
