Was there a serial killer who ate his or her parents?

Answer 1

There are several cases that brings up the 'nature or nurture' debate. Female serial killer Ailene Wunous, who was executed in Florida in 2002, had her natural father die in prison. Although he was not executed, he was a life-time criminal. At the time of his suicide (in his prison cell) he was serving several life terms for child molestation. Serial killer Gerald Gallego, who was executed in Nevada*, was a second generation death row inmate. Gallego's father Gerald Albert Gallego was sent to Mississippi's death row for the murder of two police officers. The elder Gallego had the privilege to be the first man executed in Mississippi's gas chamber after the state updated from the electric chair. Unfortunately the prison staff gave Gallego a less-than-lethal dose of cyanide. The prisoner coughed and weazed for an eternal 45 minutes before the correct dose was finally administered and Gallego died shortly after. *Gallego (the son) also had a death sentence in California.

Answer 2

Although I could find no evidence of this it is entirely possible. Keep in mind that official records of such deeds were not kept until the mid to late 1800's. There are accounts of similar deviations such as the serial killer Edmond Kemper of northern California. Kemper not only killed his grandparents but his mother and one of her friends. Kemper then proceeded to to have sex with his mother's decapitated head.

There seems to be no limit to the cruel and outrageous behavoir of the human animal. Kemper is but one example of many of a life gone completely wrong.
