Life Sentences for Two Men in Croydon Knife Murder Case

Keahn Williams and Kai Nelson-Palmer convicted for the premeditated murder of Lucas Sutton

Two young men have been sentenced to life imprisonment after being found guilty of the murder of Lucas Sutton, a 22-year-old, during a premeditated knife attack in Croydon, south London.

Keahn Williams, 20, from Coulsdon, received a minimum sentence of 23 years, while 17-year-old Kai Nelson-Palmer from Croydon was sentenced to 16 years in prison.

Their convictions were made public following the removal of reporting restrictions by the court.

The incident occurred on May 23, 2023, when Sutton was lured to a flat on Princess Road.

Following a brief visit to a local shop with the accused, he was fatally attacked in Northbrook Road.

Williams produced a knife and struck Sutton unexpectedly, resulting in a critical injury.

Sutton attempted to flee the scene but was pursued by Williams, who inflicted further stab wounds.

Despite managing to enter a nearby pub in search of help, he succumbed to his injuries shortly after emergency services arrived.

Detective Chief Inspector Brian Howie, who led the investigation for the Metropolitan Police's Specialist Crime Command, provided details on the planning and execution of the attack.

Evidence presented at trial indicated that Sutton had unknowingly been drawn into a trap designed by individuals he once considered friends.

The motivation for the murder stemmed from perceived betrayal, as Sutton had previously attempted to dispose of a firearm that was in his possession, which angered Williams and Nelson-Palmer.

Howie emphasized the calculated nature of the crime, describing it as a 'callous act' that has profoundly affected Sutton’s family and friends.

In their emotional statement, Sutton's family expressed their grief, stating that his murder has left an irreplaceable void in their lives.

They highlighted the devastating impact on Sutton's young son, who will grow up without his father.

Moreover, the investigation revealed communications between the defendants leading up to the murder, characterized by Snapchat messages that suggested premeditation.

CCTV footage captured Williams during the attack, as he wore a distinctive balaclava, which was later recovered from a location associated with him.

In addition, a 19-year-old man who faced charges related to Sutton's murder was acquitted during the proceedings at the Old Bailey on April 3, 2025. This case reflects ongoing concerns about knife crime and gang-related violence in urban areas across the UK, prompting discussions regarding public safety and youth engagement.
