Here's the OTHER Death at the Centre of Netflix's The Staircase

Jean-Xavier de Lestrade's The Staircase alludes to the haunting centre of novelist Michael Peterson's infamous murder case. Nearly two decades before Michael's wife Kathleen was found lifeless at the bottom of a staircase, there was a woman named Elizabeth Ratliff whose death would become crucial to the prosecution's story. When re-examined, Elizabeth's relationship with Michael's family and the details of her passing thicken the plot of this engrossing true crime case.

Who Was Elizabeth Ratliff?

When the Petersons resided in Germany, Elizabeth had worked in the same school as Michael's then wife Patty. Michael, a Vietnam War vet, bonded with Elizabeth's husband George, who was a captain in the military. Shortly before Elizabeth passed away, George died of a heart attack during the U.S. invasion of Grenada. The widow grew even closer with the Peterson family. She often ate dinner with the Petersons, and Michael would help her clean up and tuck her children to sleep.

The Scene of Her Death

The 43-year-old died in 1985 in Germany, found at the bottom of her stairs by her children's nanny Barbara Malagnino. It's believed that Michael was the last person to see her alive. At the time, the German police ruled her death an accident and an autopsy concluded that she died of a brain hemorrhage. During Michael's trial, Cheryl Appel-Schumacher, one of the late schoolteacher's friends, recalled that Elizabeth had severe headaches a few days before she was found dead. She also remembered the copious amounts of blood near the staircase at the scene of Elizabeth's death. After her passing, Michael adopted Elizabeth's two daughters, Martha and Margaret. When he separated from his wife, he brought his sons and the Ratliff children to the United States.

The Exhumation

Noticing the uncanny similarities with Kathleen's case, prosecutors took a closer look at Elizabeth's death in 2003. Investigators exhumed her grave in Bay City, Texas. Upon examination, forensic pathologist Deborah Radisch, who also worked on Kathleen's case, said that Elizabeth's injuries were inconsistent with an accident. In her opinion, the seven lacerations on her head indicated blunt force trauma. Elizabeth's updated autopsy report indicated that she died from homicidal assault. The prosecution used the evidence to draw parallels in court, but never formally charged Michael with Elizabeth's death. The defence countered these claims, arguing that half of Elizabeth's brain was missing during the new autopsy and pushing against the idea that Michael was the last person to see her alive.

Some speculate that Michael shared an illicit affair with Elizabeth. The author's ex-wife Patty maintains that their relationship was platonic and that her ex-husband is innocent. Michael's adopted daughters also believe that he did not kill their biological mother. Elizabeth's death is a tragedy, but whether it was brought upon by an ill-fated accident or contemptuous murder, we'll never know.
