A man who chased a teenager down the street before fatally stabbing him in the neck has been found guilty of his murder.

16-year-old Keane Flynn-Harling from Lambeth was found in Kibworth Street, Lambeth, on July 5 with a stab wound to his neck.

Sadikee Williams, 37, of Robsart Street, Brixton was found guilty of his murder on Friday after a trial at Isleworth Crown Court.

Sentencing will take place on June 8.

Police were called to Kibworth Street just before midnight on July 5 2021 by members of the public who heard Keane’s cries for help.

Keane was pronounced dead by paramedics less than 45 minutes after the incident.

He had died as a result of a single deep stab wound to his neck but had also received a significant injury to his face during the attack.

The motive for the killing remains unclear.

Williams and at least two other men had been on the balcony of a first floor flat in Sturminster House on Kibworth Street.

As Keane walked past the flat with two of his friends, one of the men shouted out to him and a short exchange took place.

Williams left the address and ran towards Keane, stabbing him in the neck.

He then chased Keane’s friends with two other men, but they were able to escape.

A week later Williams was arrested after officers were able to identify him because of a distinctive jacket he had been seen wearing at the time of the murder.

The same jacket was found at the Sturminster House flat during searches by officers.

Data from Williams’ mobile phone also confirmed his location at the address.

Williams replied no comment to all questions, until he was shown CCTV from the day of the murder where he could be seen wearing the jacket and admitted it was him in the footage.

At trial he admitted being at the flat but denied leaving the property to carry out the attack.

On July 14 last year he was charged with murder and possession of an offensive weapon.

Detective Inspector Adam Guttridge, Specialist Crime South, said: “Williams is a dangerous individual who did not hesitate in killing a teenage boy in cold blood.

“Whilst his reasons for carrying out the murder remain unknown, what we do know is that the moment he saw Keane and his friends that evening he was intent on causing serious harm and had no regard for the consequences or devastation he would cause.

“Keane’s family have had to suffer this unbearable loss because of his actions.

“While Williams made efforts to hide his tracks, it was thanks to the efforts of the officers in their meticulous work around CCTV and mobile phone analysis, as well as the testimonies of a number of key witnesses that we were able to present such a strong case and secure this prosecution.”

Keane's family said: “Keane was a beautiful, kind, caring and loving son. A wonderful young man who would always light up a room.

“He had a huge smile and an even bigger heart.

“His family meant everything to him.

“He was a doting older brother and cousin who enjoyed riding bikes and playing football with his friends.

"Keane’s presence will be sadly missed by all who had the pleasure of knowing him, especially his mother, father, brothers and sister.”
