A father and his two sons have been convicted of killing 25-year-old Devon Jensen-Wallace in Brent, north-west London.
Mr Jensen-Wallace was chased down and stabbed in the leg with a machete by Elvis Grant, 51, and his sons Jamal, 31, and Lamar, 26.
The weapon hit his femoral artery, and he bled to death.
Mr Jensen-Wallace had met two friends on Neasden’s St Raphael’s Estate around 6pm on June 1 last year, before walking around the area and visiting shops.
They were near Overton Close when “two or three men” - one armed with a machete-type knife and another with a baseball bat - crept up on them from a bin area and confronted them.
The group of friends ran away, but as they were being chased Mr Jensen-Wallace was stabbed in the leg.
As the attackers chased them, one could reportedly be heard shouting something like “you can’t get away with this, you can’t run away”.
Cameras recorded the pursuit, with one attacker holding the large knife and another shouting the encouragement of “get him”.
Mr Jensen-Wallace was found in Henderson Close around 6.30pm, bleeding heavily from a wound to his right leg.
Police and paramedics rushed to the scene, but despite their efforts to save him he was pronounced dead at 7.15pm.
A post-mortem gave the cause of death as a single wound to the leg that had cut the femoral vein, causing fatal blood loss.
When police began probing the attack they were met with a “wall of silence” from eyewitnesses.
“At the scene it was clear that there were gang members present and these gang members spread fear through the local community,” said a Met Police spokesperson.
“Neither of Devon’s friends, who were with him when he was attacked, would cooperate with the investigation.
“Members of the public would speak to officers privately, but repeatedly stated they were afraid of repercussions if they spoke openly.”
The murder investigation quickly focused on the Grant home, as Jamal Grant had previously been assaulted and it was thought he may have blamed Mr Jensen-Wallace.
Detectives executed a search warrant at the Grants’ home in Pitfield Way, Neasden.
A black baseball bat was found in the kitchen, which testing showed bore a fingerprint from Lamar Grant and blood from Mr Jensen-Wallace.
“Faced with residents who were in fear of reprisals if they spoke to police, the investigation had to work hard to secure evidence,” said the Met.
“In some cases, [they] had to accept that some [people] were simply too afraid to help.
“However, things they were told in confidence were respected and detectives worked hard to give support to those brave enough to talk to them.”
Police carried out a reconstruction, examined hours of CCTV and forensically investigated phone records.
Lamar and Jamal Grant were arrested between June 5 and 8 last year, and their father Elvis Grant was arrested in February this year.
All three denied any involvement, but all three were charged with murder.
At the Old Bailey on Tuesday, all three were convicted of their roles in Mr Jensen-Wallace’s death.
Jamal and Elvis Grant were convicted of murder, while Lamar Grant was convicted of manslaughter.
All three were also convicted of perverting the course of justice.
They are due to be sentenced on August 8.
