Details of the stabbing
Brent shooting: Family seeks justice two years after Tikquaan Stephenson-Walters killed
Metropolitan Police continue to investigate the fatal shooting of the 28-year-old near Queen’s Park.
Police were called to Tollgate Gardens at about 21:40 on 19 December after a report of a stabbing. Officers found Mr Marchoud collapsed outside a ninth‑floor flat with a serious wound to his abdomen. He was taken to St Mary’s Hospital but died later that night. Court evidence said Douglas arrived at the building to visit a former housemate, demanded entry, and after being let inside, seized a kitchen knife. He confronted Mr Marchoud, who was unknown to him, and stabbed him before following the victim out of the flat and delivering a fatal wound.
After the attack, Douglas fled through the building, threw the knife from a second‑floor window and climbed onto the roof of the entrance block. He then jumped to the ground and moved towards Kilburn High Road. CCTV footage, mobile phone data and witness statements helped reconstruct his movements.

Our thoughts remain with Khalid's family and loved ones, who continue to live with the devastating consequences of Douglas' actions.
