CLEVELAND – Was heredity to blame for the violent crimes of convicted serial killer, Michael Madison? A Cuyahoga County jury was presented with that possibility in the courtroom of Judge Nancy McDonnell on Tuesday.

Dr. Mark Cunningham, a clinical and forensic psychologist from the state of Washington, testified heredity was an aspect of sexual offending.

“There is patterning within these family systems,” he said, “They found that having a brother or father who had been convicted of a sexual offense increased the odds of being convicted of a sexual offense four to five fold.”

Cunningham prepared a diagram showing the history of Madison’s family dating back to his great-grandfather. The chart illustrated how the serial killer’s relatives preyed on each other physically and sexually, including their own children. Social Service records and interviews with Madison’s family revealed he was abused for years by his mother and her boyfriends.

“The way that he was treated is the template of how he then goes about interacting with others throughout his life,” said Cunningham, “It’s a core principle that the FBI’s behavioral science unit identified as they looked at the histories of sexual homicide offenders and observed that the quality of attachments to parents and other members of the family during childhood is central to how the child will relate to and value other members of society.”

The 37-year-old was convicted of raping and murdering Angela Deskins, Shetisha Sheeley and Shirellda Terry, all of East Cleveland. Their bodies were found near his East Cleveland apartment in July of 2013.
