THE murder of vulnerable man Phillip Nicholson will be explored in depth in a new television show which airs for the first time tonight.

Mr Nicholson, 22, was killed at the hands of his ex-girlfriend Isabella Gossling and her new partner Richard Moors.

The former Winchelsea School pupil, who lived in supported accomodation in Parkstone, was lured to Gossling's flat in Sea Road, Boscombe, on May 26, 2015, before being attacked for 17 minutes.

The fatal assault was filmed on Gossling's phone before the killers were seen on CCTV leaving the property holding hands.

The couple, who got engaged hours after the vicious attack, were jailed for life after Gossling, then 20, was found guilty of murder following a trial at Winchester Crown Court and Moors, then 26, pleaded guilty to the same offence at Portsmouth Crown Court.

Judge Alan Wilkie ordered that Moors must serve at least 22 years behind bars and Gossling at least 19 years.

The harrowing crime has now been explored by broadcaster Dermot Murnaghan for the second season of the five-part true-crime series Killer Britain with Dermot Murnaghan.

Mr Murnaghan was joined on the show by former Detective Chief Inspector of the Metropolitan Police, Clive Driscoll, best known for securing the convictions for the murder of South London teenager Stephen Lawrence.

In each episode, the television journalist recounts a crime he has reported on or followed at close quarters.

In the case of Mr Nicholson's death, the show is set to look back on the sadistic game played by Gossling and Moors which resulted in the death of the innocent young man.

The broadcast will explore the tragic case of exploitation, bullying, and ultimately murder. 

The episode of Killer Britain with Dermot Murnaghan examining Mr Nicholson's murder airs at 9pm tonight, June 3, on Crime + Investigation.
