The brand new miniseries, which is a dramatisation of acclaimed documentary The Staircase, delves into the tragic 2001 death of Kathleen Peterson and the criminal trial that followed.

Colin Firth stars as the novelist and local politician who was named the prime suspect in the death of his wife, Kathleen, played here by Academy Award nominee Toni Collette.

Peterson was convicted of murder in October 2003 following a long trial, but this verdict was thrown out eight years later when a judge found that a blood analyst for the prosecution had given false and misleading testimony.

In the retrial, Peterson submitted an Alford plea, which allowed him to continue asserting innocence while acknowledging there is enough evidence to convict, for voluntary manslaughter.

This resulted in a reduced sentence, allowing him to be released in 2017.

But what are the real life people that The Staircase is based on up to now, more than two decades on from the tragedy that gripped America?

RadioTimes.com has delved into the real story behind HBO Max's The Staircase to determine what happened to Michael Peterson, and where he is today.

Now 78 years old, Michael Peterson remains a free man.

In 2019, his former defence lawyer David Rudolf revealed that he was living in a ground-floor home with no staircase, describing that as a "really important" condition of the accommodation (via Oxygen).

It is understood that he lived with his first wife, Patricia, for a period of two years (via People), but she sadly passed away last summer after suffering a heart attack.

Since his release, Peterson has resumed writing war novels, as well as two books about his trial, conviction and time in prison: Behind The Staircase and Beyond The Staircase.
