A fresh true crime series from the creator behind Netflix's Jeffrey Dahmer tale has left audiences both revolted and baffled.

The newest production from renowned director Ryan Murphy chronicles the chilling saga of Ed Gein, the individual who emerged as one of 'the most heinous murderers in American history' following his killing and corpse-stealing rampage across 1950s Wisconsin.

This recent addition to Murphy's 'Monster' anthology, which also explores the Lyle and Erik Menendez narrative, examines the psyche of the notorious murderer for the first time; yet, numerous mysteries persist.

Twisted Gein earned the moniker The Butcher of Plainfield, with his abhorrent acts serving as inspiration for fictional villains, including Hitchcock's Psycho and The Silence of the Lambs character Buffalo Bill.

Within his residence, officers uncovered vessels crafted from skulls, disguises fashioned from flesh stripped from human faces, and a skull plus "face mask" subsequently verified as belonging to one of Gein's casualties - 54-year-old local pub proprietor Mary Hogan.

Gein faced arrest for Mary's murder alongside that of another 58-year-old woman named Bernice Worden. The deranged killer, aged 51 at the time, admitted to both murders.

Bernice's decapitated and disembowelled head was discovered on Gein's property, with the victims bearing a striking resemblance to Gein's mother.

Gein's gruesome crimes against women are fairly well-documented, but the enigma surrounding his brother's death has left Netflix viewers hungry for more information.

In the inaugural episode of the new series, audiences witness Gein violently assaulting his older brother Henry (Hudson Oz) - striking him in the head with a piece of timber and subsequently blaming a fire when the police arrive.

Despite no fire being visible, officials note bruising on the body. In the series, Henry appears to be the murderer's first victim, yet Gein was never found guilty of Henry's death - so what truly transpired?

Edward Theodore Gein, born on 27 August 1906, was the second son of George Gein and Augusta Gein, who, as per Harold Schechter's 1989 book 'Deviant', had been hoping for a daughter.

George Gein was reportedly an alcoholic who physically abused both his sons. He passed away from heart failure on 1 April 1940, aged 66.

Following their father's demise, Ed and his brother Henry assumed responsibility for the farm, whilst also taking on various jobs in the local area, including handyman work.

Ed's elder brother, Henry, grew increasingly worried about Ed's unhealthy attachment to their fervently religious mother, Augusta. Among the two brothers, Henry was considered the more well-adjusted.

Henry began a relationship with a divorced mother of two and had plans to move in with her. In May 1944, they decided to burn marsh vegetation away from the family property - a common farming practice at that time.

However, the local fire brigade had to be called in to help control it. After the fire was extinguished, Ed reported his 43-year-old brother, Henry, missing.

His body was later discovered lying face down on the property grounds. Reports from that period indicate he hadn't been burnt and seemed to have been dead for some time.

The official cause of death was asphyxiation leading to heart failure, due to the smoke from the fire.

In subsequent reports about the incident, biographer Harold Schechter claimed that Henry was found with bruises on his head. In his book 'Deviant: The Shocking True Story of the Original 'Psycho', Schechter wrote that police initially ruled out foul play.

Given that Henry appeared to have been dead for some time when he was found, Schechter speculated that Ed may have played a part. A year later, their mother Augusta suffered a massive stroke and passed away.

The horrific murders raised suspicions about Ed's involvement in Henry's death, which he consistently denied.

Gein pleaded not guilty by reason of insanity and was deemed unfit to stand trial. He was sent to Central State Hospital for the Criminally Insane (now part of the Dodge Correctional Institution) in Waupun and later transferred to the Mendota Mental Health Institute in Madison.

In subsequent interviews, Gein continued to deny any involvement in his brother's death, right up until he died from lung cancer in a psychiatric hospital on 26 July 1984, at the age of 77.
