Overview

This episode examines the mysterious death of Kathleen Peterson, known as the 'Staircase Murder.' Part two focuses on shocking revelations about Michael Peterson's past, including another woman's suspicious staircase death in Germany, Michael's bisexuality and extramarital affairs, and the controversial trial that captivated public attention. The case raises profound questions about justice, reasonable doubt, and the limitations of forensic science.

Elizabeth Ratliff's Death and Exhumation

A decade before Kathleen's death, Michael's friend Elizabeth Ratliff was found dead at the bottom of a staircase in Germany, with Michael being the last person to see her alive. The prosecution petitioned to exhume her body, and a second autopsy revealed stunning similarities to Kathleen's death. Dr. Deborah Radish concluded that Elizabeth's injuries were inconsistent with a fall and instead indicated multiple blunt force impacts that were sufficient to have caused her death.

  • Michael was the last person to see Elizabeth Ratliff alive before she was found dead at the bottom of stairs in Germany
  • Durham DA petitioned for exhumation to find similarities between the two deaths
  • Dr. Radish concluded Elizabeth's death was inconsistent with a fall and showed blunt force trauma
  • The second autopsy revealed injuries remarkably similar to Kathleen's, indicating homicide rather than natural causes
" It is my further opinion that these injuries were incurred while Mrs. Ratliff was alive and are of sufficient severity to have caused her death. "
" Forcibly would indicate that somebody was forcing your head into a... Falling somewhere is a passive act. "

Family Fractures and Civil Lawsuits

The revelations about Michael's past created devastating rifts within the Peterson family. Caitlin Atwater, Kathleen's biological daughter, filed a wrongful death lawsuit against Michael, alleging he intentionally killed her mother. The family dispute escalated when Michael claimed entitlement to Kathleen's $1.4 million life insurance policy despite being indicted for her murder, providing prosecutors with an additional motive.

  • Caitlin filed a wrongful death lawsuit alleging Michael intentionally and maliciously killed Kathleen
  • Michael claimed he should receive the $1.4 million life insurance payout despite murder charges
  • Michael only had $600,000 from a book deal while Kathleen's job was at risk, making insurance money a compelling motive
  • Margaret and Martha initially resisted exhumation but eventually approved it hoping to prove Michael's innocence
" I'm really, really saddened that the loving family that Kathleen worked so hard on for 13 years has been ripped apart. Not only have they lost a mother now they've lost their sister as well. It is a family disaster. "
