​True Crime Fans Will Love This New Psychological Documentary

Episode eight of Making a Monster, which airs on Crime+Investigation, will examine the actions of some of the world's most infamous murderers and try to unravel the hidden motivations behind their actions.

This episode follows the story of Michael Ross, who murdered eight girls and women in the Eighties. He was the last person to be sentenced to death in Connecticut and was executed in 2005.

The programme will tell the story of Ross's life, from his birth to death, with expert insight from psychiatrist and sexologist Dr Fred Berlin.

In the gripping episode, Berlin describes how he appeared as an expert witness in Ross's trial and how he supported him in his attempts to bring forward his death penalty, after the killer showed remorse.

"He was outwardly very respectable, had a decent job, even committed some of his offences while wearing a three-piece suit," said forensic psychologist Dr Adrian Needs in a clip of the show.

The programme goes on to explain how Ross was unique amongst serial killers as he turned himself in and explained his crimes in unparalleled detail, "offering an insight into the mind of a serial killer", a voiceover announces.

Experts on the docuseries will try to explain how certain life events can lead to shocking crimes and what exactly makes a monster.

Making a Monster is part of the channel's Serial Killer Season, a series of programmes delving into the most infamous killers in recent history.

Other programmes in the series include Very Scary People and The Hunt for Ted Bundy, while Making a Monster: The Tapes, a podcast accompanying Making a Monster, gives exclusive access to extra interview recordings from the forensic psychiatrists and psychologists and is presented by Cherry Healey.

Making a Monster will air on CRIME+INVESTIGATION on Monday 23 March. Previous episodes are available to watch on demand through the channel.
